Location
NOTE: The numbers in parentheses are Reference Numbers
located in the Parts List exploded views of 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.
Motor and Controller
The P Series pump shaft can rotate in either direction, therefore
direction of motor shaft rotation is not critical.
Accessories
Consult installation drawing below for typical precision metering
fluid system components. Contact Wanner Engineering or the
distributor in your area for more details.
Important Precautions
Adequate Fluid Supply. To avoid cavitation and
premature pump failure, be sure that the pump will have
an adequate fluid supply and that the inlet line will not be
obstructed. See Inlet Piping on page 6.
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 on page 6.
Safety Guards. Follow all codes and regulations regarding
installation and operation of the pumping system.
Shut-Off Valves. Never install shut-off valves between
the pump and discharge pressure regulator, or in the
regulator bypass line.
Consult the Factory for the following situations:
• Extreme temperature applications (above 160°F or
below 40°F)
• Pressure feeding of pumps
• Viscous or abrasive fluid applications
• Chemical compatibility problems
• Hot ambient temperatures (above 110°F)

P100 Installation
Inlet Piping
Provide for permanent or temporary installation of a compound
pressure gauge to monitor the inlet pressure. To maintain
maximum flow, the pump inlet should be under flooded suction
conditions at all times. 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 fluid to escape. The tank size should be at
least twice the maximum pump flow rate.
Install a separate inlet line from the supply tank to each
pump.
Place a cover over the supply tank, to prevent foreign objects
from falling into it.
Hose Sizing and Routing
To minimize acceleration head and frictional losses, size the
suction line at least one size larger than the pump inlet, and
keep the suction line as short and direct as possible.
Recommendations:
• Keep inlet lines less than 3 ft. (1 m) long
• Use at least 5/8” (16 mm) I.D. inlet hose
• Minimize fittings (elbows, valves, tees, etc.)
Inlet Piping (Pressure Feed)
Provide for permanent or temporary installation of a pressure
gauge to monitor the inlet pressure. Pressure at the pump inlet
should not exceed 250 psi (17.3 bar). For higher pressures
install a pressure reducing valve. Do not supply more than
one pump from the same inlet line.
Note: System back pressure must exceed the pump inlet
pressure by at least 15 psi (1 bar) in order to prevent flow
thru.
Discharge Piping
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
1500 psi (103 bar) W.P. rated hose for a system to be operated
at 1000 psi (69 bar) gauge pressure.
Support the pump and piping independently.
Pressure Regulation
Install a pressure relief valve in the discharge line. Bypass
pressure must not exceed the pressure limit of the pump.
Size the valve 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 relief 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 valve.
Route the bypass line to the supply tank.
CAUTION: Never install shutoff 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.
Minimum Discharge Pressure
To ensure proper capacity control, a minimum discharge
pressure of 50 psi (3.5 bar) is required.

P100 Installation
Calibration Procedure
Each individual metering pump put into service must be calibrated
in order to accurately determine required pump speed to achieve
the desired flow. The capacity curves shown on page 3 represent a
typical pump; individual pumps may vary slightly from these curves.
In order to achieve the best possible results, perform calibration
under actual process conditions. Follow these steps:
1. Run the pump for 20 minutes at actual process conditions. If
the process system cannot be used, circulate back to the supply
tank through a pressure relief valve (see Installation drawing on
page 5). If required system pressure is less than 50 PSI (3.5
bar) a back pressure valve must be installed and set to produce
a minimum of 50 PSI (3.5 bar) pressure at the pump head.
2. Determine maximum pump speed required for all system
conditions that need to be satisfied. Measure pump delivery
at this maximum speed using your system calibration cylinder,
flow meter, or some other means. This is considered to be the
“rated capacity” for your particular metering pump.
3. Measure pump delivery at 75%, 50%, 25%, and 10% of the
maximum speed just determined. Let the pump run for 5
minutes at each speed setting before taking the capacity
measurement.
4. Plot these values on linear graph paper using the horizontal
axis for RPM and the vertical axis for GPH, or any other unit of
measure you may be using for capacity.
5. Draw a best-fit straight line through the points just plotted. For
stable conditions, this line predicts pump speed required to
achieve desired flow over a 10:1 turndown ratio.
Note: as pump discharge pressure increases, capacity
decreases slightly. For any metering pump there are a
series of valid capacity curves that may apply. Use the
curve that depends on actual pump discharge pressure
and other system conditions. It is critically important to
develop a custom capacity curve for each pump and each
system.
Initial Start-Up Procedure
Before you start the pump, be sure that:
• All shut-off valves are open, and the pump has an adequate
supply of fluid.
• All connections are tight.
• The oil reservoir beneath the reservoir diaphragm (71) is
completely full. NOTE: The reservoir is filled and sealed
at the factory. If you are unsure about the oil level, remove
the cover (70) and slowly lift the diaphragm (71). Refer to
6. Fill and Seal the Oil Reservoir in the Fluid-End Service
Section.
1. Open the priming valve on the system back pressure valve
so the pump starts under minimum pressure.
2. Turn on power to the pump motor.
3. Check the inlet pressure or vacuum. To maintain maximum flow,
the pump inlet should be under flooded suction conditions at
all times. Inlet pressure must not exceed 250 psi (17.3 bar).
4. Listen for any erratic noise and look for unsteady flow.
• Jog the pump on and off until fluid coming from the
priming valve is air-free.
• Close the priming valve.
P100 Maintenance
NOTE: The numbers in parentheses are Reference Numbers
located in the Parts List exploded views of this manual.
Periodically
Change the oil according to the guidelines below. When
changing, remove the drain plug (69), Allow all oil and
contaminant to drain out. Catch the oil and dispose of it
properly.

NOTE: Minimum oil viscosity for proper hydraulic end
lubrication is 16-20 cST (80-100 SSU).
CAUTION: Do not turn the drive shaft while the oil reservoir
is empty.
There should be no trapped air under the oil reservoir diaphragm
(71). Refer to 6. Fill and Seal the Oil Reservoir in the Fluid-
End Service Section.
Use the appropriate Hydra-Oil for the application.
Note: P Series replacement parts kits (complete kits and
diaphragm kits) include the appropriate oil for each specific
P Series pump configuration.
CAUTION: If you are losing oil but don’t see any external
leakage, or if the oil becomes discolored and contaminated,
the diaphragm (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.
Check the inlet pressure periodically with a gauge.

7P100-991-2400B
P100 Fluid End Service
NOTE: The reference numbers in parentheses are shown
in the Fluid End Parts List.
This section explains how to disassemble and inspect all easily-
serviceable parts of the pump.
CAUTION: Do not disassemble the hydraulic end of the
pump. For assistance, contact Wanner Engineering (612-
332-5681) or the distributor in your area.
1. Remove Manifold (3)
a. Remove all eight bolts (1) around manifold (3).
b. Remove manifold (3).
c. Inspect manifold for warping or wear around inlet and
outlet ports. If wear is excessive, replace manifold or
return it to Wanner Engineering for resurfacing.
Place a straightedge across manifold to check if it is
warped. If warped replace.
2. Inspect Valves (4-17)
The inlet and outlet valve assemblies are different (inlet
valve is larger) and face opposite directions. Inspect each
valve assembly as follows:
a. Check spring retainers (4,17), and replace if worn.
b. Check valve springs (5,16). If shorter than new spring,
replace (do not stretch old spring).
c. Check valve poppets (6,15). If worn excessively,
replace.
d. Remove valve seats (9,13) with seat puller. A seat puller
is included in Wanner Tool Kit.
Inspect valve seats for wear, and replace if necessary.
New O-rings (8,12) should be installed.
e. Check dampening washer (10), and replace if worn.
f. Reinstall inlet and outlet valve assemblies:
• Clean valve ports and shoulders with emery cloth, and
lubricate with lubricating gel or petroleum jelly (do not use
petroleum products when installing EPDM O-rings).
• Install O-rings (8,12) on valve seats (9,13).
• Inlet Valve. Insert spring retainer (17) into valve plate
(21). Then insert spring (16), valve (15), Tetra seal (14)
and valve seat (13). A flat Tetra seal O-ring (14) goes
between spring retainer (17) and valve seat (13) when
plastic retainer is used.
• Outlet Valve. Insert dampening washer (10), valve
seat (9), Tetra seal (7), valve (6), spring (5), and spring
retainer (4). Install flat Tetra seal O-ring (14) between
spring retainer (4) and valve seat (9) when plastic retainer
is used.
3. Inspect and Replace
Diaphragm (22)
a. Use 3-mm Allen wrench to remove two capscrews (20)
from valve plate (21).
b. Lift diaphragm (22) by one edge, and turn pump shaft
(use the shaft rotator from the Wanner Tool Kit) until
diaphragm moves up to “top dead center”. This will
expose machined cross holes in plunger shaft behind
diaphragm.
c. Insert plunger holder (from the Wanner Tool Kit) through
one of machined cross holes to hold diaphragm up. The
proper size tool is included in the Wanner Tool Kit. (Don’t
remove tool until new diaphragm is installed in step g
below).
d. Unscrew diaphragm (22). Use 8-mm or 5/16-in. open-end
wrench and turn counterclockwise.
e. Inspect diaphragm (22) carefully. A damaged diaphragm
generally indicates a pumping system problem. Replacing
diaphragm only, will not solve the larger problem. Inspect
diaphragm for the following:
• Small puncture. Usually caused by sharp foreign
object in fluid.
• Diaphragm pulled away from sides. Usually caused
by fluid being frozen in pump, or by over-pressurization
of pump.
• Diaphragm becoming stiff and losing flexibility.
Usually caused by pumping fluid that is incompatible
with diaphragm material.
• Diaphragm edge chewed away. Usually caused by
over-pressurizing system.
CAUTION: If a diaphragm has ruptured and foreign
material or water has entered the oil reservoir, do
not operate the pump. Check the diaphragm, then
flush the reservoir completely (as outlined below)
and refill it with fresh oil. Never let the pump stand
with foreign material or water in the reservoir, or with
the reservoir empty.
f. Clean away any spilled oil. Apply Loctite #242 Thread
locker to threads of new diaphragm (22) (or old one).
g. Install diaphragm (22) and tighten to 10 in-lbs (113 N-
cm).

8P100-991-2400B
4. Flush Contaminant from
Hydraulic End
(Only if diaphragm has ruptured)
a. With valve plate and manifold still removed (see above),
remove drain plug (69), cover (70), and diaphragm (71).
Allow all oil and contaminant to drain out.
b. Fill reservoir with kerosene or solvent. Manually turn
pump shaft to circulate kerosene and drain. Dispose of
contaminated fluid properly.
CAUTION: If you have an EPDM diaphragm, or if food
grade oil is in the reservoir, do not use kerosene or
solvents. Instead, flush with the same lubricant that
is in the reservoir.
c. Repeat step b flushing procedure.
d. Fill reservoir with fresh oil and manually turn pump shaft
to circulate oil. Drain oil.
e. Refill reservoir with fresh oil. If oil appears milky, there is
still contaminant in reservoir. Repeat steps c and d until
oil appears clean.
5. Prime Hydraulic Cell
a. With pump horizontal, fill pump housing reservoir (62)
with correct Hydra oil for application.
Note: P Series replacement parts kits (complete kits
and diaphragm kits) include the correct oil for each
specific P Series pump configuration.
b. All air in oil within hydraulic cell (behind diaphragm) must
be forced out by turning shaft and pumping piston. A shaft
rotator is included in the Wanner Tool Kit.
Turn shaft until bubble-free flow of oil comes from
behind diaphragm. Watch oil level in reservoir. If oil
gets too low during priming air will be drawn into piston
(inside hydraulic end). Air will cause pump to have loss
in flow and repriming will be necessary. Fill oil reservoir
completely. Add diaphragm seal and install cover
plate.
c. Wipe excess oil from reservoir cover (70) and reservoir
diaphragm (71).
P100 Fluid End Service
6. Fill and Seal Oil Reservoir
a. Reservoir diaphragm (71) protrudes down into pump
housing approximately 1/4 to 3/8 in. Add oil, if required,
so that when diaphragm is set into reservoir all air is
pushed out.
Take care not to allow any oil overflow to get between
pump housing (62) and cover (54). This may result in an
apparent oil leak later, when the pump is put into use and
heats up.
b. Install reservoir cover (70) using four bolts (72).
c. Wipe off excess oil on outside of pump housing.
NOTE: The reservoir diaphragm (71) will flex up and
down slightly as the pump operates. The vent holes in
the reservoir cover (70) allow this to freely occur.
7. Reinstall Valve Plate (21) and
Manifold (3)
a. Reinstall valve plate (21), with valve assemblies installed
as outlined above, onto diaphragm plate (24).
b. Reinstall O-rings (18,19) onto valve plate (21). Use
petroleum jelly or lubricating gel to hold them in place
(do not use petroleum products when installing EPDM
O-rings).
c. Reinstall manifold (3) onto valve plate.
d. Insert bolts (1) around edge of manifold, and alternately
tighten opposite bolts until all are secure. Torque to 90
in-lbs (1017 N-cm).
e. Recheck all bolts for tightness.

Problem Probable Cause Solution
Motor/Pump
Does Not
Operate:
No power. Supply correct power according to motor requirements.
Blown fuse/tripped circuit
breaker.
Replace/reset, eliminate circuit overload.
Shaft coupling to pump not in
place.
Install proper coupling hardware (see parts list).
Current overload - motor. Motor not rated for pump operating conditions - install proper motor.
Thermal overload - motor. Motor not rated for pump and/or ambient operating conditions - supply
cooling or install proper motor.
Faulty motor drive/controller. Repair/replace.
Faulty motor. Repair/replace.
Low liquid level in supply tank
(if low-level shut-off is used).
Fill tank.
No Delivery
Supply tank empty. Fill tank.
Inlet line or strainer clogged. Clear debris and flush, or replace.
Inadequate supply pressure at
pump inlet.
Increase supply pressure by raising fluid level in tank, raising tank, or
pressurizing suction tank.
Inlet line too restrictive. Increase inlet line diameter and/or decrease inlet line length.
Fluid viscosity too high. Reduce viscosity if possible (by heat or some other means). Increase inlet
line diameter and/or decrease inlet line length. Increase supply pressure.
Vapor lock/cavitation. Increase inlet pressure. Decrease fluid temperature.
Pump valves held open or
worn out.
Clear debris and flush, or replace (see Fluid End Service)
System relief valve actuating. Adjust relief valve, or repair, clean, or replace with new relief valve.
Delivery Too
Low and/or
Erratic
Review all Probable Causes and Solutions in Problem 2 No Delivery above.
Air leak(s) in inlet line. Locate all leaks and repair.
System back pressure too low. Adjust back pressure valve to higher setting. Install back pressure valve if
none in system.
Pumped fluid characteristics
changed.
Monitor supply tank temperature to determine if fluid is too hot (leading to
cavitation) or too cold (increasing fluid viscosity). Stabilize temperature
at suitable level to resolve problem. Check for entrapped air in the fluid
supply system.
Inlet supply pressure changed. Monitor inlet supply pressure (at the pump) to determine if it is too low,
causing a starved condition/cavitation. Stabilize pressure at suitable level
to resolve problem.
Pump OK - Calibration system
or flow meter error.
Evaluate components and repair/correct problem(s).
Oil condition in pump hydraulic
end changed.
Check oil level - if low evaluate for source of leakage. Consult factory for
hydraulic end service.
Change oil per recommended guidelines in maintenance section.
Delivery Too
High and/or
Erratic.
System back pressure too low. Adjust back pressure valve to higher setting. Install back pressure valve if
none in system.
Inlet supply pressure changed. Monitor inlet supply pressure (at the pump) to determine if it is too high,
causing a “flow-through” condition. Stabilize pressure at suitable level to
resolve problem.
Pump OK - Calibration system
or flow meter error.
Evaluate components and repair/correct problem(s).
