Important Precautions
Adequate Fluid Supply. To avoid cavitation and
premature pump failure, be sure that the pump will have
an adequate uid supply and that the inlet line will not be
obstructed. See “Inlet Piping”.
Positive Displacement. This is a positive-displacement
pump. To avoid severe system damage if the discharge line
ever becomes blocked, install a relief valve downstream
from the pump. See “Discharge Piping”.
Safety Guards. Install adequate safety guards over
all pulleys, belts, and couplings. Follow all codes and
regulations regarding installation and operation of the
pumping system.
Shut-O󰀨 Valves. Never install shut-o󰀨 valves between
the pump and discharge pressure regulator, or in the
regulator bypass line.
Freezing Conditions. Protect the pump from freezing.
See also the Maintenance Section.
Consult the Factory for the following situations:
• Extreme temperature applications (above 160° F or
below 40° F)
• Pressure feeding of pumps
• Viscous or abrasive uid applications
• Chemical compatibility problems
• Hot ambient temperatures (above 110° F)
• Conditions where pump oil may exceed 200° F because
of a combination of hot ambient temperatures, hot uid
temperature, and full horsepower load — an oil cooler
may be required
Location
NOTE: The numbers in parentheses are the Reference
Numbers on the exploded view illustrations found later in
this manual.
Locate the pump as close to the supply source as possible.
Install it in a lighted, clean space where it will be easy to inspect
and maintain. Allow room for checking the oil level, changing
the oil, and removing the pump head (manifold, valve plate and
related items).
Mounting
The pump shaft can be rotated in either direction.
To prevent vibration, securely attach the pump and motor to a
level, rigid base.
On a belt-drive system, align the sheaves accurately: poor
alignment wastes horsepower and shortens the belt and bearing
life. Make sure the belts are properly tightened, as specied by
the belt manufacturer.
On a direct-drive system, align the shafts accurately. Unless
otherwise specied by the coupling manufacturer, maximum
parallel misalignment should not exceed .015” and angular
misalignment should be held to 1 degree maximum. Careful
alignment extends life of the coupling, pump, shafts, and support
bearings. Consult coupling manufacturer for exact alignment
tolerances.
Safety Precautions
General Remarks
These safety / installation instructions contain fundamental
information and precautionary notes and must be kept available
to all associated with the operation of the pump. Please read
them thoroughly prior to installation, electrical connection and
commissioning of the unit. It is imperative that all other operating
instructions relating to the components of individual units are
followed.
These safety / installation instructions contain fundamental
information and precautionary notes and must be kept available
to all associated with the operation of the pump. Please read
them thoroughly prior to installation, electrical connection and
commissioning of the unit. It is imperative that all other operating
instructions relating to the components of individual units are
followed.
Each pump must be labeled by the end user to warn of any
hazards that the system process may produce; e.g. corrosive
chemicals or hot process etc.
All personnel involved in the operation, maintenance, inspection
and installation of the pump must be fully qualied to carry out
the work. The personnel’s responsibilities, competence and
supervision must be clearly dened by the operator. To the extent
that if the personnel in question is not already in possession
of the requisite know how, appropriate training and instruction
must be provided. In addition, the operator is responsible for
ensuring that the contents of the operating instructions are fully
understood by all the responsible personnel.
When installing a Hydra-Cell pump in conjunction with a motor
or motor and frequency controller the relevant manuals must
be referred to for electromagnetic compatibility. The installation
should conform to EN 61800 and EN 60204 as applicable.
All safety instructions in this manual and all relevant local health
and safety regulations must be followed.
Attention must be paid to the weight of the pump before
attempting to lift either manually or selecting appropriate lifting
equipment.

Inlet Piping (Pressure Feed)
CAUTION: When pumping at temperatures above 160° F
(71° C), use a pressure-feed system.
Install draincocks at any low points of the suction line, to permit
draining in freezing conditions.
Provide for permanent or temporary installation of a vacuum
gauge to monitor the inlet suction. To maintain maximum ow,
vacuum at the pump inlet should not exceed 7 in. Hg at 70° F
(180 mm Hg at 21° C). Pressure at the pump inlet should not
exceed 500 psi (34.5 bar); if it could get higher, install an inlet
pressure reducing regulator.
Do not supply more than one pump from the same inlet line.
Supply Tank
Use a supply tank that is large enough to provide time for any
trapped air in the uid to escape. The tank size should be at
least twice the maximum pump ow rate.
Isolate the pump and motor stand from the supply tank, and
support them separately.
Install a separate inlet line from the supply tank to each pump.
Install the inlet and bypass lines so they empty into the supply
tank below the lowest water level, on the opposite side of the
ba󰀪e from the pump suction line.
If a line strainer is used in the system install it in the inlet line
to the supply tank.
To reduce aeration and turbulence, install a completely
submerged ba󰀪e plate to separate the incoming and outgoing
liquids.
Install a vortex breaker in the supply tank, over the outlet port
to the pump.
Place a cover over the supply tank, to prevent foreign objects
from falling into it.
Hose and Routing
Size the suction line at least one size larger than the pump inlet,
and so that the velocity will not exceed 1-3 ft/sec (0.3 to 0.9 m/s):
For pipe in inches: Velocity (ft/sec) = 0.408 x GPM/Pipe ID2
For pipe in mm: Velocity (m/sec) = 21.2 x LPM/Pipe ID2
Keep the suction line as short and direct as possible. A maximum
of 3 feet (1 m) is recommended.
Use exible hose and/or expansion joints to absorb vibration,
expansion, or contraction.
If possible, keep the suction line level. Do not have any high
points to collect vapor unless these high points are vented.
To reduce turbulence and resistance, do not use 90° elbows.
If turns are necessary in the suction line, use 45° elbows or
arrange sweeping curves in the exible inlet hose.
If a block valve is used, be sure it is fully opened so that the ow
to the pump is not restricted. The opening should be at least
the same diameter as the inlet plumbing ID.
Do not use a line strainer or lter in the suction line unless regular
maintenance is assured. If used, it should have a free -ow area
of at least three times the free-ow area of the inlet.
Install piping supports where necessary to relieve strain on the
inlet line and to minimize vibration.
Inlet Piping (Pressure Feed)
Provide for permanent or temporary installation of a vacuum/
pressure gauge to monitor the inlet vacuum or pressure.
Pressure at the pump inlet should not exceed 500 psi (34.5 bar);
if it could get higher, install an inlet pressure reducing regulator.
Do not supply more than one pump from the same inlet line.

Inlet Calculations
Acceleration Head
Calculating the Acceleration Head
Use the following formula to calculate acceleration head losses.
Subtract this gure from the NPSHa, and compare the result to
the NPSHr of the Hydra-Cell pump.
Ha = (L x V x N x C) ÷ (K x G)
where:
Ha = Acceleration head (ft of liquid)
L= Actual length of suction line (ft) — not equivalent length
V= Velocity of liquid in suction line (ft/sec) [V = GPM x (0.408 ÷
pipe ID2)]
N= RPM of crank shaft
C= Constant determined by type of pump — use 0.04 for the
D-15 and G-15 Hydra-Cell pumps
K= Constant to compensate for compressibility of the uid —
use: 1.4 for de-aerated or hot water; 1.5 for most liquids; 2.5
for hydrocarbons with high compressibility
G= Gravitational constant (32.2 ft/sec2)
Friction Losses
Calculating Friction Losses in Suction Piping
When following the above recommendations (under “inlet
Piping”) for minimum hose/pipe I.D. and maximum length,
frictional losses in the suction piping are negligible (i.e., Hf = 0)
if you are pumping a water-like uid.
When pumping more-viscous uids such as lubricating oils,
sealants, adhesives, syrups, varnishes, etc., frictional losses in
the suction piping may become signicant. As Hf increases, the
available NPSH (NPSHa) will decrease, and cavitation will occur.
In general, frictional losses increase with increasing viscosity,
increasing suction-line length, increasing pump owrate, and
decreasing suction-line diameter. Changes in suction-line
diameter have the greatest impact on frictional losses: a 25%
increase in suction-line diameter cuts losses by more than two
times, and a 50% increase cuts losses by a factor of ve times.
Consult the factory before pumping viscous uids.
Minimizing Acceleration Head and Frictional Losses
To minimize the acceleration head and frictional losses:
• Keep inlet lines less than 3 ft (1 m) long
• Use at least 1-1/2 in. (38 mm) I.D. inlet hose
• Use soft hose (low-pressure hose, noncollapsing) for the
inlet lines
• Minimize ttings (elbows, valves, tees, etc.)
• Use a suction stabilizer on the inlet.
Net Positive Suction Head
NPSHa must be equal to or greater than NPSHr. If not, the
pressure in the pump inlet will be lower than the vapor pressure
of the uid— and cavitation will occur.
Calculating the NPSHa
Use the following formula to calculate the NPSHa:
NPSHa = Pt + Hz - Hf - Ha - Pvp
where:
Pt = Atmospheric pressure
Hz = Vertical distance from surface liquid to pump centerline (if
liquid is below pump centerline, the Hz is negative)
Hf = Friction losses in suction piping
Ha = Acceleration head at pump suction
Pvp = Absolute vapor pressure of liquid at pumping temperature
NOTES:
• In good practice, NPSHa should be 2 ft greater than NPSHr
• All values must be expressed in feet of liquid
Atmospheric Pressure at Various Altitudes
Altitude Pressure Altitude Pressure

500 33.3 2000 31.5
1000 32.8 5000 28.2
Discharge Piping
NOTE: Consult the Factory before manifolding two or more
pumps together.
Hose and Routing
Use the shortest, most-direct route for the discharge line.
Select pipe or hose with a working pressure rating of at least
1.5 times the maximum system pressure. EXAMPLE: Select
a 3000-psi W.P.-rated hose for systems to be operated at
2000-psi-gauge pressure.
Use about 6 ft (1.8 m) of exible hose between the pump and
rigid piping to absorb vibration, expansion or contraction.
Support the pump and piping independently. Size the discharge
line so that the velocity of the uid will not exceed 7-10 ft/sec
(2-3 m/sec):
For pipe in inches: Velocity (ft/sec) = 0.408 x GPM/Pipe ID2
For pipe in mm: Velocity (m/sec) = 21.2 x LPM/Pipe ID2

9D15-991-2400 Rev B
D/G15 & D/G17 Installation
Pressure Regulation
Install a pressure regulator or unloader in the discharge
line. Bypass pressure must not exceed the pressure limit of
the pump.
Size the regulator so that, when fully open, it will be large enough
to relieve the full capacity of the pump without overpressurizing
the system.
Locate the valve as close to the pump as possible and ahead
of any other valves.
Adjust the pressure regulating valve to no more than 10% over
the maximum working pressure of the system. Do not exceed
the manufacturer’s pressure rating for the pump or regulator.
Route the bypass line to the supply tank, or to the suction line
as far as possible from the pump (to reduce the chance of
turbulence and cavitation).
If the pump may be run for a long time with the discharge closed
and uid bypassing, install a thermal protector in the bypass line
(to prevent severe temperature buildup in the bypassed uid).
CAUTION: Never inst all shuto󰀨 valves in the bypass line or
between the pump and pressure regulator or relief valve.
Provide for permanent or temporary installation of a pressure
gauge to monitor the discharge pressure at the pump.
For additional system protection, install a safety relief valve in
the discharge line, downstream from the pressure regulator.
Before Initial Start-Up
Before you start the pump, be sure that:
• All shuto󰀨 valves are open, and the pump has an adequate
supply of uid.
• All connections are tight.
• The oil level is 1/4 in. (6 mm) above the cast surface in the
upper oil reservoir.
• The pipe plug in the pump housing has been removed and
the oil reservoir (36) has been installed. The reservoir allows
for oil expansion during pump operation, and serves as a
sight glass for monitoring condition and level of the oil. Fill
the oil reservoir 1/4 full when the pump is cold.
• The relief valve on the pump outlet is adjusted so the pump
starts under minimum pressure.
• All pulleys and belts are properly aligned, and belts are
tensioned according to specication.
• All pulleys, belts and shaft couplings have adequate safety
guards.
Initial Start-Up Procedure
1. Turn on power to the pump motor.
2. Check the inlet pressure or vacuum. To maintain maximum
ow, inlet vacuum must not exceed 7 in. Hg at 70° F (180
mm Hg at 21° C). Inlet pressure must not exceed 500 psi
(34.5 bar).
3. Listen for any erratic noise, and look for unsteady ow. If the
pump does not clear, refer to the Trouble-shooting Section.
4. If the system has an air lock and the pump fails to prime:
a. Turn o󰀨 the power.
b. Remove the pressure gauge or plug from the tee tting
at the pump outlet (refer to the illustration on page 3).
NOTE: Fluid may come out of this port when the plug
is removed. Provide an adequate catch basin for uid
spillage, if required. Fluid will come out of this port
when the pump is started, so we recommend that you
attach adequate plumbing from this port so uid will
not be sprayed or lost. Use high-pressure-rated hose
and ttings from this port. Take all safety precautions
to assure safe handling of the uid being pumped.
c. Jog the system on and o󰀨 until the uid coming from this
port is air-free.
d. Turn o󰀨 the power.
e. Remove the plumbing that was temporarily installed, and
reinstall the pressure gauge or plug.
5. Adjust the discharge pressure regulator to the desired
operating and bypass pressures. Do not exceed the
maximum pressure rating of the pump.
6. After the pressure regulator is adjusted, set the safety relief
valve at 100 psi (7 bar) higher than the desired operating
pressure. To verify this setting, adjust the discharge pressure
regulator upward until the relief valve opens. Follow the
recommendations in the above NOTE (step 4b) for handling
the uid that will come from the relief valve.
7. Reset the discharge pressure regulator to the desired system
pressure.
8. Provide a return line from the relief valve to the supply tank,
similar to the bypass line from the pressure regulator.

D/G15 & D/G17 Maintenance
NOTE: The numbers in parentheses are the Reference
Numbers on the exploded view illustrations found later in
this manual.
Daily
Check the oil level and the condition of the oil. The oil level should
be 1/4 in. (6 mm) above the cast surface in the upper oil reservoir.
For the D/G17, the oil resevoir should be 1/4 full.
Use the appropriate Hydra-Oil for the application (contact
Wanner Engineering if in doubt).
CAUTION: If you are losing oil but don’t see any external
leakage, or if the oil becomes discolored and contaminated,
one of the diaphragms (22) may be damaged. Refer to the
Fluid-End Service Section. Do not operate the pump with
a damaged diaphragm.
CAUTION: Do not leave contaminated oil in the pump
housing or leave the housing empty. Remove contaminated
oil as soon as discovered, and replace it with clean oil.
Periodically
Change the oil after the rst 100 hours of operation, then
change according to the quidelines below. When changing,
remove the drain plug cap (28) at the bottom of the pump so
all oil and accumulated sediment will drain out. Then, remove
the magnetic plug (35) and clean all accumulated debris from
it. Replace the magnetic plug and drain plug cap and rell with
the appropriate Hydra-Oil.

NOTE: Minimum oil viscosity for proper hydraulic end
lubrication is 16-20 cST (80-100 SSU).
NOTE: Use of an oil cooler is recommended when process
uid and/or hydraulic end oil exceeds 180°F (82°C).
CAUTION: Do not turn the drive shaft while the oil reservoir
is empty.
Check the inlet pressure or vacuum periodically with a gauge.
If vacuum at the pump inlet exceeds 7 in. Hg (180 mm Hg),
check the inlet piping system for blockages. If the pump inlet
is located above the supply tank, check the uid supply level
and replenish if too low.
CAUTION: Protect the pump from freezing. Refer also to
the “Shutdown Procedure”.
Shutdown Procedure During
Freezing Temperatures
Take all safety precautions to assure safe handling of the
uid being pumped. Provide adequate catch basins for
uid drainage and use appropriate plumbing from drain
ports, etc. when ushing the pump and system with a
compatible antifreeze.
1. Adjust the discharge pressure regulating valve so the pump
runs under minimum pressure. Stop the pump.
2. Drain supply tank; open any draincocks in system piping and
collect drainage; remove plugs (0) from manifold and collect
drainage.
3. Close draincocks in system piping and replace manifold
plugs.
4. Fill supply tank with enough antifreeze to ll system piping
and pump.
Note: disconnect the system return line from the supply tank
and connect it to a separate reservoir.
5. Start the pump and allow it to run until the system is lled with
antifreeze. Note: if the system has an airlock and the pump
fails to prime, follow step 4 of the Initial Start-up Procedure
to clear the air.
6. When mostly antifreeze is owing from the system return line
stop the pump. Connect the system return line back to the
supply tank and circulate the antifreeze for a short period.
7. It is also good practice to change the oil in the Hydraulic
End before storage for an extended period. This will
remove any accumulated condensation and sediment from
the oil reservoir. Drain and rell the Hydraulic End with the
appropriate Hydra-Oil and operate the pump for a short
period to assure smooth performance.

NOTE: The number in parentheses are the Reference
numbers on the illustration in the Fluid End Parts section.
This section explains how to disassemble and inspect all easily
serviceable parts of the pump. Repair procedures for the
hydraulic end (oil reservoir) of the pump are included in a later
section of the manual.
CAUTION: Do not disassemble the hydraulic end unless
you are a skilled mechanic. For assistance, contact Wanner
Engineering (TEL [phone] or FAX [phone]) or the
distributor in your area.
CAUTION: Do not remove the four socket-head capscrews
(29) that go through the cylinder housing (25), unless you are
repairing the hydraulic end of the pump.
Tools and Supplies
The following tools and supplies are recommended for servicing
the pump:
• Straightedge (at least 8 in. long)
• Grease or petroleum jelly
• 1/2” drive torque wrench, rated to at least 50 ft-lbs (70 N-m)
• Emery cloth and Scotch-Britetm pad
• 11/16” socket (3/8” or 1/2” drive)
• 19 mm socket (1/2” drive)
• 3/8” drive socket wrench with extensions
• 1/2” drive socket wrench with extensions
• T30 torx drive
• Wanner Hydra-Oil (appropriate Grade, as determined by
digit 12 of your pump model number).
• Anaerobic seal sealant (for shaft seals if servicing Hydraulic
End)
• Wanner D-15 Tool Kit, which includes the following:
– Valve seat puller
– Plunger guide lifter
– 3/32 x 6 in. T-handle hex wrench
– 8 mm hex bit socket (1/2” drive)
– Shaft rotator
– Seal protector
– Seal inserter
– 5/16” hex Allen wrench
– 7/16” 8-point socket (3/8” drive)
– 6 mm hex Allen wrench
Service Procedures
Begin with the pump assembly removed from the system, and
the pump disconnected from the motor and motor adapter.
Secure the pump baseplate (32) to a stable workbench with
clamps, or bolts and nuts (the bolts passing through the unused
holes in the solid portion of the baseplate).
1. Remove Manifold and Valve
Plate (4, 26)
a. Manifold. Use the 8 mm hex bit socket included in the
Wanner D-15 Tool Kit to remove the 12 capscrews (2) and
ve capscrews (1) at the front of the manifold. Remove
and inspect the manifold for warping or wear around
the inlet and outlet ports and ow channels. If wear is
excessive replace the manifold. To check if the manifold
is warped, place a straightedge across it; check both
sides. A warped manifold should be replaced.
b. Valve Plate. Using the 8 mm hex bit socket remove
capscrew (24). Remove and inspect the valve plate in
the same manner as the manifold, for excessive wear or
warping. Replace if necessary.
CAUTION: Don’t turn the pump drive shaft while the
manifold and valve plate are o󰀨 the pump, except when
removing diaphragms or repriming the hydraulic cells.
2. Remove and Inspect
Valves (9-20)
NOTE: Wanner Valve Kits include items and all O-rings for
sealing the manifold to the valve plate. The ve inlet and
ve outlet valve assemblies are di󰀨erent in size and face
in opposite directions.
a. Remove the inlet valve seat (10) using the seat puller tool
included in the Wanner D-15 Tool Kit. Inspect the valve
seat for wear, and replace if necessary.
NOTE: Whenever any valve or seat is replaced it is
recommended to replace all valve assemblies to ensure
the most reliable operation. All necessary parts are
included in a replacement Valve Kit.
b. Remove the remaining inlet valve components (11-14)
and outlet valve components (17-20) by hand or with a
small needle nose pliers.
c. Check the spring retainers (14, 20) and replace if worn,
cracked, or damaged.
d. Check the valve springs (12, 19) and replace if worn,
broken, or shorter than a new spring. Never attempt to
stretch a used spring.
e. Check the valves (11, 18) for wear or damage and replace
if necessary. Polishing of the valves during operation is
normal. If you can feel a ridge in the valve surface the
valve should be replaced.
NOTE: Pumps with plastic spring retainers (14, 20)
include a Tetra Seal (13, 17 - square section O-ring)
between the spring retainer and valve seat. Pumps with
metal spring retainers do not include a Tetra Seal.

12 D15-991-2400 Rev B
D/G15 & D/G17 Service (Fluid End)
f. Reinstall the valve assemblies:
• Clean the valve ports and shoulders in the valve plate
(26) with a Scotch-Brite pad or ne emery cloth. Wash
the valve plate after cleaning, and lubricate the valve
ports with a compatible grease, oil, or petroleum jelly.
• Install new O-rings (9, 15) on seats (10, 16) and
lubricate all O-rings.
• Inlet Valves (ve center, larger valves). Insert the
spring retainer (14) into the valve plate (26), followed by
the Tetra seal (13) if spring retainer is plastic. Insert the
spring (12) into the retainer, followed by the valve (11)
onto the spring. Finally, insert seat (10) with new O-ring
into the valve bore with the larger I.D. chamfer (seating
surface) facing down, towards the valve.
• Outlet Valves (ve outer, smaller valves). Insert the
outlet seat (16) with new O-ring into the valve bore with the
larger I.D. chamfer (seating surface) facing up. Insert a
Tetra Seal (17) if valve spring retainers are plastic. Insert
the valve (18) and spring (19) onto the seat. Finally, insert
the spring retainer (20) into the valve bore.
• Make sure the springs are all properly nested into the
spring retainers to ensure proper valve performance.
3. Inspect and Replace
Diaphragms (22)
a. Lift a diaphragm by one edge, and turn the pump shaft
until the diaphragm moves up to “top dead center”. This
will expose machined cross-holes in the spool valve (55)
behind the diaphragm.
b. Insert a 3/32 x 6 in. hex wrench through one of the
machined cross-holes, to hold the diaphragm up and to
keep the valve plunger from rotating. The proper size tool
is included in the Wanner Tool Kit. (Don’t remove the tool
until the new diaphragm is installed in step “f” below.)
c. Unscrew the diaphragm. Use a T30 Torx bit, and turn
counterclockwise.
d. Inspect the diaphragm carefully. A damaged diaphragm
generally indicates a pumping system problem and
replacing only the diaphragm will not solve the larger
problem. Inspect the diaphragm for the following:
• Half-moon marks. Usually caused by cavitation of
pump (See Troubleshooting section).
• Concentric circular marks. Usually caused by
cavitation of pump (See Troubleshooting section).
• Small puncture. Usually caused by sharp foreign
object in uid, or by ice particle.
• Diaphragm pulled away from center screw or from
cylinder sides. Usually caused by uid being frozen
in pump, or by overpressurization of pump.
• Diaphragm sti󰀨 and inexible. Usually caused
by pumping uid incompatible with diaphragm
material, or diaphragm operated at temperatures
below rated capability.
• Diaphragm edge chewed away. Usually caused by
overpressurizing system.
CAUTION: If a diaphragm has ruptured and foreign
material or water has entered the oil reservoir, do
not operate the pump. Check all diaphragms, then
ush the reservoir completely (as outlined below)
and rell it with fresh oil. Never let the pump stand
with foreign material or water in the reservoir, or with
the reservoir empty.
e. Clean away any spilled oil.
f. Install a new diaphragm and tighten to 18 in.-lbs (203
N-cm).
g. Repeat the above inspection procedure (and replacement,
if necessary) with the other four diaphragms.
4. Flush Contaminant from
Hydraulic End
(only if a diaphragm has ruptured)
a. With the valve plate and manifold still removed (see
above), remove the oil drain cap (28) allow all oil and
contaminant to drain out.
b. Fill the reservoir with compatible solvent, manually turn
the pump shaft to circulate the kerosene, and drain.
Dispose of this contaminated uid properly.
c. Repeat the ushing procedure (step “b” above).
d. Fill the reservoir with fresh oil, manually turn the pump
shaft to circulate the oil, and drain again.
e. Rell the reservoir. If the oil appears milky, there is
still contaminant in the reservoir. Repeat the ushing
procedure until the oil appears clean.
5. Prime the Hydraulic Cells
Method #1 (system head
pressure less than 2 psi)
a. With the pump horizontal and the uid end head
removed, ll the reservoir with the appropriate Hydra oil
for the application. Have a catch basin for oil that leaks
from behind the diaphragms when priming. Catch the
oil and dispose of it properly; do not reuse it.
b. All air in the oil within the hydraulic cell (behind the
diaphragm) must be forced out by turning the shaft (and
thus pumping the piston). A Shaft Rotator is included
in the Wanner D-15 Tool Kit. Rotate the shaft two
revolutions and rell the reservoir. Rotate it two more
revolutions and rell again. Continue to do this until the oil
that is being pumped from the back of all ve diaphragms
is free of air.
c. Wipe excess oil from the cylinder housing (25) and
diaphragms (22).
d. Ensure that the oil level is 1/4 in (6 mm) above the cast
surface in the upper oil reservoir.
e. Replace oil ll cap (30).

13 D15-991-2400 Rev B
D/G15 & D/G17 Service (Fluid End)
6. Reinstall Valve Plate and
Manifold (26, 4)
a. Reinstall the valve plate (26), with the valve assemblies
installed as outlined above, onto the cylinder housing
center spud and alignment pin (8).
b. Install capscrew (24) with at washer (3) through center
hole in valve plate and torque to 45 ft-lbs (60 N-m).
c. Install new O-rings (5, 6, 7) into the grooves in the front
side of the valve plate. Use grease or petroleum jelly to
hold them in place.
d. Reinstall the manifold (4) over alignment pin (8), engaging
the center spud of the manifold into the center of the valve
plate.
e. Install capscrews (1) with at washers (3) through the ve
center holes in the manifold. Thread each capscrew in
several turns, but do not torque.
f. Install capscrews (2) with at washers (3) through the
twelve outer holes at the perimeter of the manifold.
Thread each capscrew in several turns, but do not torque.
g. Return to the ve capscrews at the center of the manifold
and alternately tighten opposite bolts until all are secure.
Torque to 45 ft-lbs (60 N-m).
h. Return to the twelve capscrews at the perimeter of the
manifold and alternately tighten opposite bolts until all
are secure. Torque to 45 ft-lbs (60 N-m).
i. Recheck all capscrews for tightness and proper torque,
starting with the ve at the center of the manifold, then
the twelve at the perimeter.
Method #2 (with system head
pressure greater than 2 psi)
NOTE: This simple and clean method of priming the
Hydra-cells requires an inlet head pressure of at least 5
feet (1.5 m) or 2 psi (.14 bar). This pressure is required
to hold the diaphragms back while the piston moves to
force out the air.
a. Completely assemble pump.
b. Fill reservoir with correct Hydra-oil. For D/G17, remove
Oil Bottle and ll to top of ll port.
When tank head pressure is being used to prime,
use the following steps:
c. Install pump in system and connect tank supply line to
pump inlet. Connect pump discharge line. Leave end of
line open to allow air to pass out.
d. Slowly turn pump shaft by hand and watch for bubbles at
oil reservoir ll opening. This will take several rotations.
When no more bubbles come out and reservoir level has
dropped about 1” (25 mm), hydraulic cells are primed.
e. For D/G17, replace reservoir (30) and complete installation.

14 D15-991-2400 Rev B
D/G15 & D/G17 Service (Hydraulic End)
NOTE: The numbers in parentheses are the Reference
Numbers on the exploded view illustrations found later in
this manual.
This section explains how to disassemble and inspect the
hydraulic end (oil reservoir) of the pump.
CAUTION: Do not disassemble the hydraulic end unless
you are a skilled mechanic. For assistance, contact Wanner
Engineering (612-332-5681) or the distributor in your area.
CAUTION: The four socket-head capscrews (31) that screw
through the cylinder housing (25) into the pump housing
hold these parts together. Do not remove these four screws
except when repairing the hydraulic end.
NOTE: The following service procedures refer several times to
the Wanner D-15 Tool Kit. We strongly urge you not to repair
the hydraulic end of the pump without using the tools in this Kit
(available from Wanner Engineering or your local distributor).
Refer also to the list of tools and supplies in the Fluid-End
Service Section.
Service Procedure
NOTE: Before Step 1 Remove Pump Housing, scribe a line
on the perimeter of the cylinder housing and onto the pump
housing. This will simplify alignment during reassembly.
1. Remove Pump Housing
a. Remove the manifold and valve plate, and the diaphragms,
from the pump. Refer to the Fluid-End Service Section
b. Drain the oil from the pump housing by removing the
drain plug cap (28). Dispose of the oil properly.
For D/G17 only: Drain the oil from the pump housing by
removing plug (36), then tipping the pump up onto the
cylinder housing (25). Remove oil reservoir (39), clean
and set aside. Return the pump to its secure horizontal
position.
c. Check the shaft for sharp burrs. Smooth any burrs, to
prevent scarring the seals (47) when removing the shaft.
d. Reinsert two perimeter bolts (2) through the cylinder
housing (25) into the pump housing (39), at the 10 and
2 o’clock positions, to support the parts as the pump is
being disassembled.
e. Remove the four socket-head capscrews (31) loosening
alternately so the cylinder housing separates evenly from
the pump housing. Slide the cylinder housing out on
the two bolts (2) that were inserted for support in Step d
above. The preload on the piston return springs will push
the cylinder housing out of the pump housing. Remove
the support bolts and cylinder housing assembly.
NOTE: the piston assemblies will be free to slide out
of the cylinder housing, so keep the cylinder housing
orientated with pistons up, for later disassembly.
f. Remove the shaft assembly (45) sliding the shaft out of
the seals (47). The parts are heavy.
g. Remove the bearing adjustment plate (43) and inspect
the bearing cup (45A). Inspect all parts for wear, and
replace if necessary.
h. Inspect the cam and bearings (45), and the bearing cup
(45B) in the housing. If the bearings are pitted or binding,
or if the bearing cup in the housing is worn, contact
Wanner Engineering.
CAUTION: If a bearing cup or bearing cone is replaced,
they must be replaced as a pair or premature failure will
result.
2. Disassemble Pistons
Inspect and clean all parts of the hydraulic piston assemblies
(61). Replace all O-rings and any other parts that are worn
or damaged.
3. Reassemble Pistons
a. Drop a ball (59) into each opening in the bottom of the
piston assembly (60).
NOTE: Using grease on the O-rings, and lubricating the
parts, will aid in assembly.
b. Insert a retaining washer (58) and O-ring (57) to hold the
balls in place.
c. Insert a valve plunger (55) into the valve cylinder (56).
Slide priming spring (54), spacer (53), and overll spring
(52) over the valve plunger (55), inside the valve cylinder
(56).
d. Insert an O-ring (51) into the spring retainer (50).
e. Slide the assembled valve cylinder (56), valve plunger
(55), priming spring (54), spacer (53), and overll spring
(52) into the spring retainer (50).
f. Slide the complete cylinder-and-retainer assembly into
the piston assembly.
g. Insert a piston return spring (49) into the piston assembly,
with the larger end going into the piston rst. This is a
tight t, and can best be done by “screwing” the spring
in counterclockwise.
h. Repeat the above procedure for the other four pistons.
4. Remove Shaft Seals (47)
Inspect the shaft seals (47) before continuing. If they look
damaged in any way, replace them. Remove by pounding
them out from inside the pump housing. Replace both shaft
seals at the same time. Clean the bore in the housing using
emery cloth or Scotch-Brite™.
5. Reassemble Pump Housing
(39), Cam Assembly (45),
and Cylinder Housing (25)
a. With the pump housing vertical and the baseplate
removed, set it with the open end up on a workbench.
Grease the groove at the face of the housing and install
O-ring (48). Set aside.
b. Set the cylinder housing, with the diaphragm pockets
facing down, onto smooth, clean, 4” high blocks. Insert
the bearing adjustment plate (43), with the bearing cup
(45A) and dowel pin (44) into the cylinder housing. The
dowel pin engages into the largest of the ve slots in the
cylinder housing.
c. Insert the ve piston assemblies into the cylinder housing.

15 D15-991-2400 Rev B
D/G15 & D/G17 Service (Hydraulic End)
d. Set the cam assembly onto the cylinder housing sub-
assembly such that the piston feet support the cam
assembly and the nose bearing is centered over bearing
cup (45A). Note: the cam assembly will be able to move
from side to side slightly, as the nose bearing is not fully
engaged into the bearing cup.
e. If the shaft seals (47) are still in the pump housing, slide
the seal protector (from the D-15 Tool Kit) over the shaft.
Pick up the pump housing, lining up the marks made
earlier on it and the cylinder housing. Slowly lower the
pump housing over the shaft until the bearing cup (45B)
rests on the upper bearing of the cam assembly.
f. Start the four capscrews (31) by hand, using the 6 mm
hex Allen wrench from the Wanner D-15 Tool Kit. Thread
them through the counter bored holes in the cylinder
housing, engaging the threads into the pump housing.
Two full turns of each screw should be able to be achieved
before noticeable resistance is met from the piston return
springs. If this cannot be done remove the pump housing
and check alignment of the cam assembly to the cylinder
housing subassembly.
g. Install baseplate (32) onto pump housing using capscrews
(34) and lockwashers (33). The longer end (stamped
FRONT) of the baseplate goes toward the cylinder
housing. Apply thread locker (e.g. Loctite 242) to the
threads of the capscrews and torque to 45 ft-lbs (60 N-m).
h. Lift the pump assembly o󰀨 of the 4” blocks and set it onto
the workbench. Tip the pump assembly so it sits upright
on the baseplate.
Return to the four cylinder housing capscrews
(31) and tighten them to establish and maintain an
even gap between the cylinder housing and pump
housing. This will draw the cylinder housing into the
pump housing, compressing the ve piston return
springs and the six disk springs that pre-load the
cam assembly. Note: there is very minimal clearance
between the cylinder housing pilot diameter and the
main pump housing bore, so it is very important
to alternately tighten the four capscrews, until the
housings are ush together. The last 1/8” (3mm)
requires more force to bring the housings together
as all of the springs are nearing their maximum
compression. Torque all four capscrews to 15 ft-lbs
(20 N-m). Remove the shaft seal protector.
6. Install Shaft Seals (47)
a. Apply a thin lm of grease on the seal protector tool
(included in the Wanner D-15 Tool Kit). Slide both seals
onto the tool, with the spring side of the seals toward
the open end of the tool. Apply a heavier coat of grease
between the seals and press them together.
b. Apply an anaerobic seal sealant or bearing retaining
compound (e.g. Loctite 601 or 609) to the outside
diameter of the seals.
c. Apply a light lm of grease to the pump shaft and slide
the seal protector (with seals) over the shaft.
d. Slide the seal inserter tool (included in the Wanner D-15
Tool Kit) over the seal protector tool, and press the seals
completely into place. Tap the tool with a soft mallet to
rmly seat the seals ush to the pump housing.
7. Reinstall Diaphragms (22)
a. Screw the plunger guide lifter (from the Wanner Tool
Kit or Repair Kit) into the valve plunger (55). Pull out to
expose the cross holes in the plunger. Rotate the shaft
until the piston is at top dead center.
b. Insert the 3/32-in. T-handle hex wrench (from the Wanner
Tool Kit), through the plunger hole — to hold the plunger
away from the cylinder housing (25), and to keep the
plunger from turning when the diaphragm is being
installed.
c. P lace diaphragm (22) and follower (23) onto valve plunger
(21).
d. Hold the T-handle hex wrench to secure the valve plunger,
and torque the diaphragm insert to 18 in.-lbs (203 N-cm)
using a T30 Torx Drive.
e. Repeat the above procedure for the plungers and
diaphragms of the other four cylinders.
f. Fill the reservoir with fresh oil and prime the pump, as
outlined in the Fluid-End Service Section.
8. Reassemble Pump
Reassemble the pump as outlined in the Fluid-End Service
Section.
