INSTALLATION
PUMP INSTALLATION
The installation of your Waukesha pump and its piping system should follow the practices described to give
optimum performance, and be in accordance with local codes and restrictions.
All system equipment, such as motors, sheaves, drive couplings, speed reducers, etc., must be properly sized
to insure satisfactory operation of your Waukesha pump within its limits.
CAUTION: Waukesha pumps are positive displacement, low slip design and will be severely damaged if operated with closed valves in discharge or inlet lines. Pump warranty is not valid for damages caused by a hydraulic overload from operation or start-up with a closed valve in the system.
WARNING
Full coupling guards must be installed to isolate operators and maintenance
personnel from rotating components. Coupling guards are provided with
Waukesha pumps as a part of a complete pump and drive package.
1. Installing the Pump and Drive Unit. Pumps of this type can be mounted on a common base plate with the
drive. The unit can be installed in several ways:

Adjustable leg base, commonly used for sanitary
pumps. For washdown under base. Can be easily
moved or repositioned.
Permanent installation on foundation with bolts and

INSTALLATION
WARNING
TO AVOID SERIOUS INJURY, DO NOT INSTALL OR SERVICE PUMP UNLESS
ALL POWER IS OFF AND LOCKED OUT.
2. Good Piping Practice.
All piping to the pump should be supported independently, to minimize the forces exerted on the pump. Such
forces can cause misalignment of pump parts and lead to excessive wear of rotors, bearings and shafts.
NOTE: Pump dimensions and pump weights
are on page 7.
A. Piping support:

F. ''Isolation'' Valves-permit pump maintenance and
removal safely and without emptying entire system.
G. Relief Valve
To protect the pump and piping system against excessive pressure, a relief valve should be installed. An
integral relief valve, designed to bypass the fluid internally from the pump outlet to the inlet, should not be
used on applications where the discharge must be
closed for more than a few minutes. Prolonged operation
of the pump with closed discharge will cause heating of
the fluid circulating through the relief valve. When such
operation is necessary, the relief valve, whether integral, attachable, or line-mounted, should discharge externally through piping connected to the fluid source, or
if that is not practical, into the inlet piping near the
source.

Inlet Side-Strainers and Traps.
Inlet side strainers and traps can be used to prevent
pump damage from foreign matter. Selection must be
carefully made as clogging can easily occur, restricting
the inlet, causing cavitation and flow stoppage.
MAGNETIC TRAP
Pressure Gauges
Pressure and Vacuum gauges provide the easiest way
to tell you something about the pump operation.
• Normal or abnormal pressures
• Overload conditions
• Indication of flow
• Changes in pump condition
STRAINER
• Changes in system conditions
• Changes in fluid viscosity
3. Alignment of Pump to Drive.
Pumps and drives which are ordered from the factory
and mounted on a common base plate are accurately
aligned before shipment. The alignment should be
rechecked after the complete unit has been installed
and the piping completed. Periodic rechecking is
advisable during the pump service life.
In-line Drives. For initial pump installation, and for rechecking alignment, the following steps are
advised:
Use a flexible coupling to connect the drive to the pump. Many different types are available, including couplings with slip or overload provision.

START-UP CHECK LIST
The Waukesha Pump is a positive displacement pump and thus can develop very high pressures.
To protect lines, equipment and personnel, certain precautions must be taken.
1.
Review page 9, particularly "Relief Valves". Install relief valves if needed.
2.
Check that piping and pump are clean and free of foreign material, such as welding slag,
gaskets, etc. Do not use pump to flush system.
3.
See that all piping connections are tight and leak-free. Where possible, check system with
“non-hazardous” fluid.
4.
Check to see that pump and drive are lubricated. See page 14. Check Drive
Lubrication Instruction.
5.
Check that all guards are in place and secure.
6.
Seals: Double mechanical and double O-ring seals with flushing require adequate supply and
flow of clean flushing fluids.
7.
See that all valves are open on discharge system, and that free flow path is open to
destination.
8.
See that all valves are open on inlet side, and that fluid can reach pump.
9.
Check direction of pump and drive rotation. (See page 11)
10. Start pump drive. Where possible, start at slow speed, or jog.
Check to see that liquid is reaching pump within several minutes. If pumping does not begin and stabilize,
check items under “No Flow” or “Insufficient Flow” on (Page 15)
Troubleshooting a Pumping System.

SHIM STACK
5. Before continuing, a critical measurement must be taken to determine the need for a bearing shim.
measure the distance between the fluid head mounting surface and the rotor seat surface on the corresponding shaft. Do this for both shafts. If both dimensions are the same, then no shims are needed. If
there is a difference, then a shim must be added to the shaft assemble with the shortest dimension.
The thickness of the shim is equal to the difference between the two measurements.
6. If a shim is required, it must be added at this time. Remove the appropriate shaft and the front bearing
seat, and place the required shim(s) in the front bearing bore. Then reinstall the front bearing seat and
shaft assembly.
7. Recheck the measurement made in step 5. Allowable differences between the two shafts will be ±.001”.
MEASURE BOTH SHAFT S. APPLY SHIM UNDER

FLUID HEAD
MOUNTING PLATE
FLUID HEAD
(BODY)
If the shafts and bearings or just the shafts were
replaced, in all probability, the fluid head will
probably need to be reshimmed to achieve the
proper rotor to body backface clearance. The
Model 420 and 520 pumps are designed to
acomplish this without removing the shafts from
the gearcase. All fluid head shimming is done
between the fluid head (body) and the fluid head
mounting plate as described in the following
proceedure.
1. Install the pump fluid head on the gearcase.
Make sure that all mating surfaces between the
fluid head mounting plate and the gearcase
mounting surface are clean and free of all burrs.
The shaft seals need not be installed for this
operation, and it is much simpler if they are not.
2. Measure the height difference between the rotor
seat surface on the shaft and the end of the
body shaft hub. The rotor seat surface on the
shaft should protrude above the hub by .009”
±.001”. Measure both of the shafts and record
each.
MEASURE DISTANCE BETWEEN HUB SHAFT
SHOULDER AND ROTOR SHOULDER
3. If the measurement differs from the dimension
stated in step 2 shims will have to be added or
removed from between the fliud head and the
fluid head mounting plate. If the measurement is
OK, then go to step 8.
4. Remove the fluid head from the gearcase.
5. Remove the four retaining bolts from each fluid
head mounting plate. One at a time, remove
each mounting plate and add or subtract shims
(P/N 100472-100476) until the desired height is
reached. (Example: If step 2 yielded a measurement of .005”, then .004” of shim would need
to be added to the existing shim stack.)
SHIM
MOUNTING PLATE
6. Reinstall the fluid head mounting plates over the
new shim stack and secure with the socket head
retaining bolts. Torque the bolts to 70 ft-lbs.
7. Repeat steps 1,2 and 3 above.
8. Remove the fluid head from the gearcase.
Refer to the section on fluid head assembly for the
complete the reassembly process.

3. The leading edge of the outer seal should be
.610-inches from the shaft shoulder. Fasten
seal in place by tightening the two setscrews.
4. Install the gland plate.
5. Install the gaskets on both sides of the T-seat.
Lubricate the faces on the T-seat with a food
grade lubricant or other approved fluid and
install the T-seat.
6. The inner seal may be assembled prior to
installing on shaft. Care should be taken to
make sure that all springs are properly seated
and that the seal face drive pins are properly
aligned with the notches in the inner seal face.
Use food grade lubricants on all O-rings during
seal assembly to enhance performance.
7. Install the inner seal.

Aseptic/Steam Purge Models
Flushing Connection
Aseptic pumps may be installed for horizontal or vertical product flow.
The flanged ports and cover both have extra flush connection ports located to
optimize the flow when used in either position.
The unused flush ports must be plugged before placing the pump and flush
system in service.
NOTE: Flushing media may be piped into either side for both shaft seals and
discharged to drain on opposite side. Both inlets may be manifolded to simplify
piping. Be sure flush water is flowing out both discharge lines.
Piping for steam should be determined in accordance with local codes.
Low Pressure Flush
Restrictor
Flush In
1.
Set a flow rate of approximately 1/4 GPM for most applications. For high
temperature applications, increase the flow. The flowrate supplied must be
adequate to purge the system.
2.
Flushing media is restricted on the inlet side and has free flow to drain on the
outlet side.
3.
Typical flushing connections are 1/8" NPT female pipe taps.
Flush Out
Flush In
Flush Out
Flushing Connection - "Aseptic Series"
All connections are 1/8" female pipe taps. The pump has double "barriers" or
seals at every opening to the pump chamber. Live steam or a sterile fluid is
circulated between these double seals at the ports, in the cover and at the shaft
seals.
