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:

GUARD

GUARD

Adjustable leg base, commonly used for sanitary pumps. For washdown under base. Can be easily moved or repositioned.

GUARD

Permanent installation on foundation with bolts and grout. (Level unit before grouting.)

GUARD

Leveling and/or vibration isolation pads.

Portable bases-for movement to different locations.

Many Commercail types are available.

2. Good Piping Practice.

ALL POWER IS OFF AND LOCKED OUT.

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:

Thermal expansion of piping-can cause tremendous forces. Use thermal expansion joints to minimize forces on pump.

B.

UPRIGHT MOUNTING SHOWN

B. Flexible joints can also be used to limit the transmission of mechanical vibration. Anchor free ends of any flexible hose in system.

Piping Layout

C. Inlet side: Slope piping up to inlet to avoid air pocket.

D. Inlet side-use check valves to keep inlet line full, particularly with low viscosity fluids, and in start-stop operation.

E. Inlet Vacuum Service-use check valve on outlet side.

• Prevents backflow (air or fluid).

• Facilitates initial start-up (minimizes differential

pressure pump must supply to start flow).

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.

INSTALLATION

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.

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

• 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.

95-03025 13

OPERATION

Normal operation covers a speed range of 0-600 RPM and pressure range of 0-200 PSI. Temperature range with standard rotors is -40° to 200° F. and with hot clearance rotors, 180° to 300° F. (For operation at higher tempera-

tures, consult Waukesha Cherry-Burrell.)

See START-UP CHECK LIST (Page 13) and TROUBLESHOOTING (Page 15-18) for additional operation information.

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”.

MAINTENANCE

SHIM LOCATION

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.

FLUID HEAD

MOUNTING PLATE

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.

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.)

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.

9. *Tighten the setscrews in the inner seal seat

retainer.

10. Remove the rotor retaining nut and preload tool.

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.
