supplied, an external bypass valve MUST be used.
PRE-INSTALLATION CLEANING
NOTICE:
This pump contains some residual test fluid and rust
inhibitor. If necessary, flush pump prior to use.
Foreign matter entering the pump WILL cause extensive
damage. The supply tank and intake piping MUST be
cleaned and flushed prior to pump installation and operation.
LOCATION AND PIPING
Pump life and performance can be significantly reduced when
installed in an improperly designed system. Before starting
the layout and installation of the piping system, review the
following suggestions:
1. Locate the pump as near as possible to the source of
supply to avoid excessive inlet pipe friction.
2. The inlet line should be at least as large as the intake
port on the pump. It should slope downward to the pump,
and should not contain any upward loops. Eliminate
restrictions such as sharp bends; globe valves,
unnecessary elbows, and undersized strainers.
3. Install a system bypass valve that returns excess flow to
the supply tank or pump inlet piping as appropriate for
the pumping system. Insure that the bypass valve
pressure setting is appropriate for the pump and system
component working pressures.
4. It is recommended a strainer be installed in the inlet line
to protect the pump from foreign matter. The strainer
should be located at least 24" (0.6m) from the pump, and
have a net open area of at least four times the area of
the intake piping. Strainers must be cleaned regularly to
avoid pump starvation.
5. The intake system must be free of all leaks.
6. When pumping liquids at elevated temperature,
provisions should be made to compensate for expansion
and contraction of the pipes, especially when long pipe
lines are necessary. Steel pipe expands approximately
3/4” (1.9 cm) per 100 feet (30.49 m) per 100°F (37.8°C)
rise in temperature.
7. Expansion joints, placed at least 36" (0.9m) from the
pump, will compensate for expansion and contraction of
the pipes. Contact the flexible connector/hose
manufacturer for required maintenance/care and design
assistance in their use.
8. ALL piping and fittings MUST be properly supported to
prevent any piping loads from being placed on the pump.
9. Install pressure gauges in the NPT ports provided in the
pump casing (if equipped) to check pump at start up.
10. Check alignment of pipes to pump to avoid strains which
might later cause misalignment. See Figure 1. Unbolt
flanges or break union joints. Pipes must not spring
away or drop down. After pump has been in operation
for a week or two, completely recheck alignment.
Figure 1

111-B00 Page 4/16
INSTALLATION
PUMP MOUNTING
A solid foundation reduces noise and vibration, and will
improve pump performance. On permanent installations it is
recommended the pumping unit be secured by anchor bolts
as shown in Figure 2. This arrangement allows for slight
shifting of position to accommodate alignment with the
mounting holes in the base plate.
Figure 2 - Pipe Type Anchor Bolt Box
For new foundations, it is suggested that the anchor bolts be
set in concrete. When pumps are to be located on existing
concrete floors, holes should be drilled into the concrete to
hold the anchor bolts.
When installing units built on channel or structural steel type
bases, use care to avoid twisting the base out of shape when
anchor bolts are tightened. Place shims as needed under the
edges of the base prior to tightening of the anchor bolts to
prevent distortion.
COUPLING ALIGNMENT
The pump must be directly coupled to a gear reducer and/or
driver with a flexible coupling. Verify coupling alignment after
installation of new or rebuilt pumps. Both angular and parallel
coupling alignment MUST be maintained between the pump,
gear, motor, etc. in accordance with manufacturer’s
instructions. See Figure 3.
1. Parallel alignment: The use of a laser alignment tool or
dial indicator is preferred. If a laser alignment tool or dial
indicator is not available, use a straight edge. Turn both
shafts by hand, checking the reading through one
complete revolution. Maximum offset should be less
than .005" (.127 mm).
2. Angular alignment: Insert a feeler gauge between the
coupling halves. Check the spacing at 90° increments
around the coupling (four checkpoints). Maximum
variation should not exceed .005" (.127 mm). Some
laser alignment tools will check angular alignment as
well.
3. Replace the coupling guards after setting alignment.
Figure 3 – Alignment Check
PUMP ROTATION
PV6,8 pumps will ALWAYS operate in the clockwise rotation
when viewed from the driven end. See Figures 4 and 5.
TO REVERSE PUMP FLOW
To reverse FLOW direction in a ProVane pump. The pumps
rotation WILL NOT CHANGE for PV 6&8. See Flow Direction
Options in the Maintenance section of this manual.
If the rotation of the electric motor driving the pump is
incorrect; see the motor manufacturer’s instructions to change
the rotation of the electric motor to match it to the rotation of
the pump.
CHECK VALVES
The use of check valves or foot valves in the supply tank is
not recommended with self-priming, positive displacement
pumps.
If the possibility of liquid backflow exists when the pump is off,
a check valve in the system is recommended because the
pump can motor in the reverse rotation and create undue
stress on all attached components. Never start a pump when
it is rotating in the reverse rotation as the added starting
torque can damage the pump and related equipment. If a
check valve is used, install it at the pump discharge.

PRE-START UP CHECK LIST
1. Check the alignment of the pipes to the pump. Pipes
must be supported so that they do not spring away or
drop down when pump flanges or union joints are
disconnected.
2. Verify proper coupling alignment.
3. Check the entire pumping system to verify that the proper
inlet and discharge valves are fully open, and that the
drain valves and other auxiliary valves are closed.
4. Install inlet and discharge pressure gauges on the pump
in the threaded connections provided. These can be
used to check actual suction and discharge conditions
after pump start-up.
5. Check the wiring of the motor, and briefly turn on the
power to make sure that the pump rotates in the direction
of the rotation arrow.
START UP PROCEDURES
NOTICE:
Consult the "General Pump Troubleshooting" section of
this manual if difficulties during start up are experienced.
1. Start the motor. Priming should occur within one minute.
2. Check the suction and discharge pressure gauges to see
if the pump is operating within the expected conditions.
3. Check for leakage from the piping and equipment.
4. Check for overheating of the pump, reducer (if equipped),
and motor.
5. If possible, check the flow rate.
6. Check the pressure setting of the system bypass valve
by slowly restricting a valve in the discharge line and
reading the pressure gauge. This pressure should be 20
psi (1.4 bar) higher than the intended operating pressure.
RUNNING THE PUMP IN REVERSE
NOTICE:
When pumps are operated in reverse a separate pressure
relief valve must be installed to protect the pump from
excessive pressure. NOTICE:
Pump should be operated in reverse rotation for no more
than 10 minutes and only when a separate pressure relief
valve is installed to protect the pump from excessive
pressure.
It may be desirable to run the pump in reverse rotation for
system maintenance. The pump will operate satisfactorily in
reverse rotation for a LIMITED time, at a reduced
performance level.

111-B00 Page 6/16
OPERATION
FLUSHING THE PUMP
NOTICE:
If flushing fluid is to be left in the pump for an extended
time, it must be a lubricating, non-corrosive fluid. If a
corrosive or non-lubricating fluid is used, it must be
flushed from the pump immediately.
To flush the pump, run the pump with the discharge valve
open and the intake valve closed. Bleed air into the pump
through the intake gauge plug hole or through a larger
auxiliary fitting in the intake piping. Pump air for 30 second
intervals to clean out most of the pumpage.
1. Run a system compatible flushing fluid through the pump
for one minute to clear out the remainder of the original
pumpage. The valve in the discharge line should be
restricted to build up 10 psi (0.7 bar) to force flushing
liquid through the bearing seal chamber.
2. To remove the flushing fluid, follow step 1 above.
3. After flushing the pump some residual fluid will remain in
the pump and piping.
4. Properly dispose of all waste fluids in accordance with
the appropriate codes and regulations.
OPTIONAL PUMP RELIEF VALVE:
An external bypass valve and/or an
internal relief valve MUST be installed in
the system to protect the pump from
excessive pressure.
Hazardous pressure
can cause personal
injury or property
damage
Incorrect bypass valve or internal relief
valve settings can cause pump
component failure, personal injury, and
property damage.
Hazardous pressure
can cause personal
injury or property
damage.
1. Blackmer ProVane pumps may or may not be fitted with
an internal relief valve. If an internal relief valve is not
supplied, an external bypass valve must be used.
2. The pump’s internal relief valve is designed to protect
only the pump from excessive pressure and must not be
used as a system pressure control valve.
3. Internal bypassing of liquid elevates liquid temperature.
Internal relief valve should only be used for brief periods
and for differential pressures below 125 psi. For
extended periods, an external bypass returned to source
must be used.
4. The pump relief valve cap must be on the inlet side of the
pump. If pump relief valve is installed improperly, it will
not operate and a component failure may result. See
Figures 4 and 5.

MAINTENANCE:
14. LOCKNUT ADJUSTMENT
It is important that the bearing locknut (24A) and lock
washer (24B) be installed and adjusted properly. Over
tightening the locknut can cause bearing failure or a
broken lock washer tang. A loose locknut will allow the
rotor to shift within the pump, causing wear.
See Figure 12.
Figure 12 – Locknut Assembly
a. On the end of the pump shaft, install a lock washer
(24B) with the tangs facing outward, followed by a
locknut (24A) with the tapered end inward. Ensure the
inner tang "A" of the lock washer is located in the slot
in the shaft threads, bending it slightly, if necessary.
b. Tighten the locknut to ensure that the bearing is
bottomed in the recess. DO NOT over tighten and
bend or shear the lock washer inner tang.
Bearing Adjustment
15. Turn the bearing adjuster counterclockwise, as viewed
from the driven end of the pump, until the shaft is snug
and no longer turns. Mark a line across the bearing
adjuster and drive housing.
16. Turn the bearing adjuster clockwise, as viewed from the
driven end of the pump the distance prescribed per table
2. Measurement to be taken on outside of drive housing.
Table 2
Pump size Distance on OD of Drive Housing
PV 6,8 3/4” (19.05 mm)
17. Tighten the bearing adjuster lock setscrews and torque
per table 1.
18. Install a new head O-ring (72) on the dowel of the head
as shown in Figure 13.
Figure 13 – Head O-ring Installation
19. Carefully install the head (23) into the cylinder. If pump
is equipped with internal relief valve, orient the relief
valve per instruction in PUMP RELIEF VALVE section
of this manual. Install and tighten four head cap screws
(21A). Torque per table 1.
20. RELIEF VALVE ASSEMBLY
a. Insert the valve into the valve body with the fluted in
inward.
b. Install the relief valve spring onto valve and spring
guide onto spring.
c. Screw the adjusting screw into the valve cover until it
makes contact with the spring guide
d. Install the relief valve cap and O-ring after the relief
valve has been properly adjusted.
NOTICE:
The relief valve setting MUST be tested and adjusted
more precisely before putting the pump into service.
Refer to “Relief Valve Setting and Adjustment”.
21. Reinstall coupling, shaft key, and coupling guards.
Operation without guards in place can
cause serious personal injury, major
property damage, or death.
Do not operate
without guard
in place
22. Refer to “Pre-Start Up Check List” and “Start Up
Procedures” sections of this manual prior to restarting
pump operation.

GENERAL PUMP TROUBLESHOOTING
NOTICE:
Maintenance shall be performed by qualified technicians only.
Follow the appropriate procedures and warnings as presented in this manual.
LEAKAGE
Location Probable Cause/Corrective Action
Between the head & casing Damaged head O-ring: Inspect and replace if necessary.
Burrs/dirt in head O-ring groove or cylinder: File and clean as
necessary.
Around the shaft New Mechanical Seals: New seals may leak slightly at start up, but
should seal up shortly thereafter.
Damaged mechanical seals: Check for damaged O-rings or cracked,
scratched or worn seal faces
SHAFT BINDING
Probable Cause Corrective Action
Burrs, dirt or foreign particles on the heads or discs. During assembly, both heads and discs must be clean and smooth. File
any burrs or rough spots, and wipe the discs with a clean cloth and
alcohol to remove any dirt or foreign particles.
Improper bearing adjustment. Bearings must be adjusted properly to center the rotor and shaft
between the head & bearing housing. Refer to the "Pump assembly "
section of this manual.
Contaminated mechanical seal faces. Any trace of grease or dirt on the seal faces will prevent the faces from
mating properly, causing the rotor and shaft to bind or turn hard. Use a
tissue paper & alcohol to clean the seal faces. NOTE: Apply a light oil
or suitable lubricant to bronze seal faces only.
OTHER POSSIBLE CAUSES OF SHAFT BINDING:
• Foreign particles on rotor, liner or vanes.
• Damaged vanes or rotor.
• Bent push rods.
• Liquids that "set up" when inactive.
OVERHEATING
Probable Cause Corrective Action
Pump is in bypass (internal or external) mode too long or
the bypass loop is too short Adjust the bypass valve and/or internal relief valve so that the pump does not operate in bypass mode so long.
Route the external bypass line back to the supply tank.
OTHER POSSIBLE CAUSES OF OVERHEATING:
• Improper system bypass valve adjustment
• Plugged discharge line.
• Closed valve.
LOW DELIVERY RATE
Probable Cause Corrective Action
Bypass valve setting too low, causing the liquid to
bypass. The Bypass valve setting should be 20 psi (1.4 bar) higher than the differential pressure.
OTHER POSSIBLE CAUSES OF A LOW DELIVERY
RATE:
Restriction in the suction line.
Resistance in the discharge line.
Air leaks in the suction line.
Damaged or worn pump parts.
Pump speed too low or too high.
Bypass valve leaking.
Bypass valve sticking open, or not properly seating.
Dirty strainer.
Liner installed backwards
Pump running in reverse

111-B00 Page 14/16
GENERAL PUMP TROUBLESHOOTING
EXCESSIVE NOISE AND VIBRATION
Probable Cause Corrective Action
Cavitation or vaporization of the liquid resulting from
excessive vacuum on the pump due to starved suction. Check for:
Inlet piping too long or too small in diameter.
Strainer plugged or dirty.
Undersized or restrictive fittings, such as globe valves or partially
closed valves.
Excessive amount of elbows.
Suction lift too great.
Pump speed too high for the viscosity of the liquid being pumped.
Entrained air or vapors in the pump. Check pipe joints for leakage of air. Sometimes when recirculating
liquid in a tank, the returning liquid falling through the air carries air
down into the tank, which eventually gets back into the pump.
Pump speeds exceed the recommended maximum. Check the recommended RPM for your specific application.
Liner Installed Backwards The word “INTAKE”, which is cast on the liner MUST be towards the
intake side of the pump
Continual or long term bypassing of liquid through system
bypass valve. Check for restriction in the discharge line, or an improper bypass valve adjustment
OTHER POSSIBLE CAUSES OF NOISE AND VIBRATION:
Excessively worn vanes
Bearing Worn or Damaged.
Loose or improperly installed piping.
Misalignment of pump and driver.
Pump base not properly mounted.
POOR OR NO PRIMING
Probable Cause
Air leaks in the suction line.
Restriction in the suction line.
Damaged or worn pump parts.
Too much lift for the vapor pressure of the fluid.
A dirty or clogged strainer.
Worn vanes.
Suction Valve Closed.
Incorrect pump rotation
Bypass Valve partially open, valve not seating properly.
DAMAGED VANES
Probable Cause
Foreign objects entering the pump.
Running the pump dry for extended periods of time.
Cavitation.
Viscosity too high for the vanes and/or pump speed.
Incompatibility with the liquids pumped.
Excessive heat.
Worn or bent push rods, or worn push rod holes.
Settled or solidified material in the pump at start-up.
Hydraulic hammer - pressure spikes.
Vanes installed incorrectly (see “Vane Replacement").
BROKEN SHAFT
Probable Cause
Foreign objects entering the pump.
Viscosity too high for the pump speed.
Bypass valve not opening.
Hydraulic hammer - pressure spikes.
Pump/driver, driveline/drive shaft misalignment.
Excessively worn vanes or vane slots.
Settled or solidified material in the pump at start-up.
SEAL LEAKAGE
Probable Cause
O-rings not compatible with the liquids pumped.
O-rings nicked, cut or twisted.
Shaft at seal area damaged, worn or dirty.
Excessive cavitation.
Mechanical seal faces cracked, scratched, pitted or dirty.
Ball bearings worn.
MOTOR OVERLOAD
Probable Cause
Horsepower of motor not sufficient for application
Improper wire size / wiring and/or voltage to motor.
Misalignment in pump drive system.
Excessive viscosity, pressure or speed.
Faulty or worn bearings.
Rotor rubbing against head or liner.
Dirty mechanical seal faces.
