Maintenance (Continued)
NOTE: Liquid soap solution - one drop of liquid soap combined with one teaspoonful of water.
5.With thumb pressure, press ceramic seal half firmly and squarely into seal cavity. Polished face of ceramic seat is up. If seal will not seat correctly, remove, placing seal face up on bench. Reclean cavity. Seal should now seat correctly (See Figure 14).
6.If seal does not seat correctly after recleaning cavity, place a cardboard washer over polished seal face and carefully press into place using a piece of standard clean 3/4” pipe as a press (See Figure 15).
IMPORTANT: Do not scratch seal face.
7.Dispose of cardboard washer and recheck seal face to be sure it is free of dirt, foreign particles, scratches and grease.
8.Inspect shaft to be sure it is free of nicks and scratches.
9.Apply liquid soap solution sparingly (one drop is suffi- cient) to inside diameter of rubber rotating member.
10.Slide rotating seal member (carbon face down toward ceramic face) and spring over the shaft.
IMPORTANT: Do not nick or scratch carbon face of seal when handling.
MOTOR REPLACEMENT
The motor can be replaced with any standard Nema 56J jet pump motor (of proper HP for each pump) by referring to the following instructions.
1.Follow steps as outlined under Rotary Seal Replacement and Pump Disassembly.
2.Remove cap screws that connect the motor to the mounting ring and pull motor away.
3.Replace motor with standard Nema 56J jet pump motor by positioning motor against the mounting frame and assembling with four (4) cap screws.
IMPORTANT: Because damage to the shaft seal can occur in disassembly, a new seal will be necessary.
PUMP REASSEMBLY
Before reassembling the pump, carefully inspect the component parts of the cartridge (stage) assembly, looking for damage, wear or heat distortion. Pay careful attention to spacing direction of components, and location of shims.
Refer to Figure 16 for proper facing and parts arrangement. If damage to Stage components is evident, a complete cartridge assembly or individual stage assemblies are available for replacement (See Replacement Parts List).
1.Reassembly should follow the reverse order of the disas- sembly procedure with special care given to replacement of the rotary seal.
2.Check top and bottom of
3.Do not use pipe compound of Teflon tape on barrel threads. The
