INTRODUCTION
GENERAL INFORMATION
GENERAL
This manual contains installation, operation, cleaning, and repair instructions, with parts list, for
PR, PRE, PRED pumps manufactured by Tri-Clover Inc. of Kenosha, Wisconsin. It also provides
a troubleshooting chart to aid in determining pump malfunctions.
WARNING
Before servicing pump, disconnect electrical
power source.
DESCRIPTION
The PR, PRE and PRED Series pump units are generally mounted on base plates which
accommodate the pump units and the drive motors.
The pump units are comprised of two sections, the pump frame section and the fluid head section.
The drive shaft and pump shaft with their respective o-rings, bearings, seal and retaining rings are
located in the inner pump frame section.
The timing gears are keyed to the shafts. Axial movement of the gears is kept to a minimum by
shaft shoulders and retaining rings.
Lip seals on the shafts and o-ring seals on the frame bores, prevent leakage of timing gear
lubricating oil into the pump bearing grease chamber.
Sealing of the fluid head along the shafts is accomplished by rotary seals, consisting of stationary
stainless steel seal rings with carbon inserts, stainless steel wear rings which are broached to fit
the shaft splines, and o-rings which seal off any pumpage.
An optional cover containing a pressure relief valve provides a positive means of protecting the
processing equipment and piping from excessive head pressures.
Rotors are available in two materials - rubber and metal. Rubber and metal rotors are available in
double and four lobe design.
The drive motors, used in conjunction with the PR, PRE and PRED Series Pumps are not covered
in this manual. Refer to the individual motor or drive manufacturer for service data.

INSTALLATION
UNPACKING AND INSTALLATION
UNPACKING EQUIPMENT
Check the contents and all wrapping when unpacking your equipment. Inspect all parts for
damage that may have occurred during shipping.
Note:
If the plastic pump port covers have been broken or disturbed in shipment,
dismantle fluid head to make sure it is free of all foreign materials before placing
pump in service.
Figure One
INITIAL LUBRICATION
Straightedge
The pump unit is lubricated at the factory prior to shipping and
will require no additional lubrication until after the pump is put
into service. When you receive the pump:
1. Remove the shipping plug from the top position in the gear
cover and install the vented plug shipped with the pump.
2. Check the oil level in the gear case. Oil should be even
with the plug opening marked with the "oil level" decal. If
oil is required, refer to the Maintenace and Repair section
on page 12 of this manual for details.

Coupling
CORRECT ALIGNMENT
Figure Two
LOCATION
Straightedge
The pump unit should be located as near as possible to the
liquid source and in a position where the suction piping can be
short and direct with a minimum number of elbows and fittings.
It should also be readily accessible for inspection, cleaning
and lubrication.
Flexible
Coupling
FLEXIBLE COUPLINGS
Taper
Gauge
ANGULAR MISALIGNMENT
The purpose of a flexible coupling is to compensate for
temperature changes, and allow end movement of the pump
and motor shafts without interference with each other while
transmitting power from the motor to the pump. A flexible
coupling should not be used to compensate for shaft
misalignment.
Figure Three
Straightedge
When properly aligned, the flexible coupling should appear as
shown in the adjoining drawing. See Figure 1.
The faces of the coupling halves should be far enough apart
so that they do not touch each other when the motor shaft is
moved toward the pump.
Flexible
Coupling
PARALLEL MISALIGNMENT
The tools required for checking flexible coupling alignment are
a straightedge and taper gauge or set of feeler gauges. See Figures 2 and 3.
-6-
INSTALLATION
FLEXIBLE COUPLING ALIGNMENT
There are two types of misalignment encountered with flexible couplings, angular misalignment
and parallel misalignment. To check for angular misalignment, insert a taper gauge or feeler
gauge at four places located 90° apart around the coupling as shown. Coupling halves will be
aligned when the measurements are the same at all check points.
To check parallel misalignment, place a straightedge across the coupling half rims at the top,
bottom and both sides, making sure that the straightedge is parallel to the motor and pump shafts.
The coupling will be properly aligned when the straightedge rests evenly on the coupling rims at all
check points.
Correct alignment is obtained by use of shims under the motor mounting feet. Remember that
adjustments made in one direction may affect alignment in another direction. Therefore, several
checks of both angular and parallel alignment should be made.
SEAL FLUSHING - PRED PUMPS
All PRED Series Pumps have double-static o-ring product seals which must have flush liquid
applied to them.
Install seal flush as shown below. Use pressurized flush with products that tend to build up
between seal faces; latex, PVA, etc. Pressure in seal chamber should exceed pump discharge
pressure by at least 10 PSI.
Note:
Your Positive Rotary Pump is designed for either clockwise or counterclockwise rotation.
It should be noted that product flow will be in the same direction as the drive shaft rotation.
Connect the flexible coupling, start the pump and operate it until temperatures are stabilized. The
unit should then be shut down and the alignment immediately rechecked.
Note:
If corrections in alignment are necessary at this time, be sure to check in all directions
after making adjustments.

INSTALLATION
PIPING HINTS
GENERAL
This section provides some do’s and don'ts of piping which will aid in obtaining the maximum
efficiency and service from your pump.
•
Piping should be independently supported at both the suction inlet and discharge outlet.
•
Care should be taken that piping is properly aligned and does not put any strain on the pump
casing.
•
The piping should have as few bends as possible.
SUCTION PIPING
•
The suction piping should be short and follow a direct route with a minimum number of elbows
and fittings.
•
Elbows should not be used at the suction inlet as friction would be greatly increased, resulting
in head loss.
•
Excessive friction losses in the suction line could result in pump cavitation, causing poor
performance, noise, vibration, damage to equipment, and possible damage to product.
•
Whenever practical, the diameter of the piping at the suction inlet should be increased in size.
•
An eccentric tapered reducer should be used in lieu of a straight concentric tapered reducer to
prevent air pockets from forming and impairing pump efficiency. In turn, the eccentric reducer
may be placed at the inlet of the pump and should be positioned so the straight side is up.
•
Although positive displacement pumps are self-priming under moderate suction lift conditions,
a flooded suction is always preferable.
DISCHARGE PIPING
•
The discharge piping should be short and direct with a minimum number of elbows and
fittings. It is advisable to increase the pipe diameter at the discharge outlet to minimize head
loss.
PRESSURE RELIEF COVER ADJUSTMENT
Tri-Clover's relief cover is designed for added protection of the pump and other processing
equipment. The product flow will stop or is reduced when the head pressure on the discharge
side of the pump exceeds the pressure rating controlling the piston in the relief cover.
The relief cover is designed for use with either manual or pneumatic controls.
To adjust, install a line pressure gauge in the discharge line of the pump as close as possible to
the discharge port. Determine a maximum line pressure rating that is higher than the operating
pressure and adjust as follows:
-8-
INSTALLATION
Manual:
1. Loosen jam nut (09B-6).
2. Turn the adjusting screw (09-5A) (clockwise to increase pressure - counterclockwise to
decrease pressure) until the reading on the pump discharge line pressure gauge is the same
as the predetermined maximum line rating - then retighten jam nut (09B-6).
Pneumatic:*
When back pressure is regulated by pneumatic control, the spring inside the relief cover must be
removed prior to the operation. To remove spring it is necessary to remove relief cover parts in
the following sequence:
1. Jam nut (09B-6).
2. Clamp (13MON-X-S).
3. Cap nut (09B-3A).
4. Retaining ring (09B-13).
*
For PR300 replace cap nut (09B-3A), adjusting screw (09B-13) and jam nut (09B-6) with
R3-1-09D-3 cap.
Reassemble relief cover omitting retaining ring (09B-13) and spring (09B-4) and follow instructions
below for pneumatic operation:
1. Loosen jam nut (09B-6).
2. Turn the adjusting screw (09B-5A) counterclockwise until o-ring (09B-14) is slightly
compressed, then retighten jam nut (09B-6).
3. Adjust pressure control valve at the source of supply (air or CO2) until the reading of the
discharge line pressure gauge is the same as the predetermined maximum line pressure
rating.

MAINTENANCE
CLEANING
WARNING
Before servicing the pump, disconnect the electrical
power source, carefully relieve all pressure, and drain all
fluids from the pump and connected piping.
DISASSEMBLY OF PUMP FLUID HEAD
It is necessary to disassemble parts of your pump for cleaning and sanitizing. Disassemble as
described below after disconnecting the suction and discharge piping. If so equipped, also
disconnect the relief cover air line.
Note:
For added protection when disassembling pump fluid head, place all parts on rubber mat
or wooden platform. Extreme care must be exercised during assembly and disassembly
of the fluid head - especially in handling of the rotary seal parts and rotors.
1. Remove casing nuts and slide the casing cover off the casing studs. Carefully remove the oring from the inside of the cover.
2. Remove the rotors from the drive and pump shafts.
3. Slide the casing off the studs.
4. Carefully remove the casing o-rings from the rear of the casing.
5. Slide the seal rings off the shaft.
6. Remove the wear rings. If necessary use Puller No. R80-200 supplied with your pump. Do
not pry wear rings off with a screwdriver or similar tool as the flanges may be damaged.
Carefully remove shaft o-rings. On PRED models, with double seal assemblies, remove rear
seal rings and o-rings.
Seals: Inspect the carbon face of the seal ring and the wear ring seal surface for nicks, scratches
or excessive wear. Inspect all o-rings for cuts, abrasions or wear. Replace any damaged or worn
parts.
Rotors: Inspect rubber rotor for cuts, cracks or other damage to the rubber composition. Inspect
metal rotor carbons for cracks or wear and replace if damaged. Check fit of metal or rubber rotors
on shafts and replace if excessively loose.

MAINTENANCE
MAINTENANCE AND REPAIR
Maintenance of the PR, PRE and PRED pumps includes frequent lubrication of the shaft bearings,
checking the oil level in the timing gear compartment, changing of oil at regular intervals, and
inspection of pump components.
LUBRICATION OF OUTBOARD AND INBOARD BALL BEARINGS
The bearings should be greased after every 100 operating hours, using a high quality grease such
as Mobile Temp #1. Old grease in the grease chamber should be periodically removed by
removing the cleanout hole cover and scraping out excess grease. Mixing of different brands of
grease should be avoided, to prevent possible chemical reactions between the brands, which
could damage the bearings. Greases containing vegetable or animal bases should not be used
because they can develop harmful acids. Also avoid using greases containing graphite, rosin, talc
and other impurities.
Note:
Be sure the lubrication fittings are wiped clean before greasing, to prevent dirt from being
forced into the bearings during greasing.
If your pump has been operated under extremely dusty or wet conditions for several months, or
has been idle for a long period of time, the bearings should be cleaned thoroughly with white
gasoline or kerosene and new grease applied. Refer to the applicable paragraph for disassembly,
cleaning and inspection procedures.
LUBRICATION OF TIMING GEARS
The timing gears are lubricated with SAE 20 oil. At regular intervals check the oil level by
removing the oil level plug. Oil should be even with the bottom of the plug opening.
Every 200 operating hours, remove drain plug and drain the timing gear chamber. Add new oil
until proper level is reached.
DISASSEMBLY
It is recommended that periodic inspection of all parts be made to prevent malfunction caused by
worn or broken parts. To accomplish this inspection, it is necessary to completely disassemble
the pump. Sequence of disassembly is the same for models PR, PRE and PRED.
Disassembly of the Casing and Rotor
1. Disconnect the suction and discharge piping. Also disconnect the water line to the shaft seal
flush assembly, if pump is so equipped.
2. Remove the four bolts securing the pump to the base plate.
Note:
If the pump is removed from the base plate, be sure that any shims used to level the
pump are fastened together by some suitable means, tagged and reinstalled at their
original location at time of reassembly.
Disconnect the flexible coupling half from the pump shaft.
3. Remove the coupling key from the shaft. Remove casing nuts and slide casing cover from
studs. Carefully remove casing cover o-ring.
4. Disassemble the relief cover, if used, by removing the jam nut, clamp, cap nut and gasket.
Remove the retaining ring and slide the adjusting screw spring and thrust washer from the
piston. Carefully remove the o-ring from the adjusting screw.

MAINTENANCE
5. Remove the piston from the relief cover and carefully remove the o-rings and PTFE sleeves
from the piston.
6. Slide off the drive shaft and pump shaft rotors.
7. Remove the casing and carefully remove the casing o-rings.
8. Slide the seal rings of the shafts and carefully remove wear rings. If necessary use Puller No.
R80-200. Do not pry off with a screwdriver or similar tool which may bend flange area of wear
ring.
Note:
Do not use a screwdriver or a pointed tool to remove seals and o-rings. The seals and
o-rings are precision parts and are easily damaged.
9. Remove the shaft o-ring by placing the thumb of one hand and forefinger across the diameter
of the o-ring and pressing it with a circular motion so that the o-ring projects from the groove.
With the forefinger of the other hand work the o-ring from the shaft groove.
10. Remove the vented plug and the oil level plug. Drain the oil from the timing gear case by
removing the drain plug. Remove the gear cover cap screws and the gear cover.
11. Carefully remove the gear cover gasket.
12. Press out the gear cover seal if replacement is necessary.
13. Remove the timing gear retaining ring (Part No. 98) from each shaft. On models PR300,
PRE300 and PRED300, bend back the tab on lockwasher (Part No. 69), and remove locknut
(Part No. 22) and lockwasher.
14. Use suitable pullers and remove the timing gears.
15. Remove the woodruff keys from shafts.
16. Remove the outboard bearing cover retaining rings.
17. Press each shaft and bearing assembly through the housing from the rotor end. If a press is
not available, a soft hammer or a block of wood can be used to drive the shaft from the
housing.
18. Remove the outboard bearing cover and o-ring. Push out the bearing cover seal if
replacement is required.
19. If it is necessary to remove the alignment locating rings, use a long punch to tap them from
the inside of the frame. Note the original positions of these rings. The grooves in the rings
must be carefully aligned with grease fittings at reassembly. Press the seal from the
alignment locating ring if replacement is necessary.
No further disassembly is recommended unless inspection shows that replacement of bearings or
shafts is required. If bearings are to be replaced, remove the bearing retaining ring. Using a
bearing puller or an arbor press, remove the damaged bearing from the shaft.

TROUBLESHOOTING
TROUBLESHOOTING GUIDELINES
Tri-Clover pumps are relatively maintenance free with the exception of sanitizing and lubrication.
Like any piece of machinery, however, occasional problems can arise. The troubleshooting chart
provides a means of determining and correcting most of your pump problems. The motor
manufacturer should be contacted for specific repair instructions on the motor.
Note:
The troubleshooting chart has been prepared on the basis that the pump as installed has
been properly suited to its application. Should problems arise where the remedies listed
in the troubleshooting chart do not cure the situation, pump cavitation may be the
problem. Symptoms of pump cavitation, such as noisy operation, insufficient discharge
and vibration, can result when a pump is not properly applied. If these conditions are
present, check the system and reevaluate the application. If assistance is required,
contact Tri-Clover.
