Drain Plug

NOTICE: While this will drain the pump, it will not necessarily drain all other parts of the piping system. If there are any concerns with the proper procedure or necessity of draining the suction plumbing, contact your contractor.

B. Pump Disassembly (Appendix I & Figure 9)

In order to access the internal components of the pump, review the exploded diagram of the pump assembly as shown on the repair parts page(Appendix I). Drain the pump as described above and then remove the four bolts that hold the pump case to the motor bracket. This will allow the motor and hydraulic sub-assembly to be removed from the case without disturbing the plumbing. Locate and inspect the diaphragm and grommet which are internal water seals. Make sure they are in good condition and are working properly. To remove the diffuser, loosen

the 3 bolts that attach it to the motor bracket. This will expose the impeller and eye-seal. Remove the eye-seal and then, in order to remove the impeller, securely hold the motor shaft with a pair of vice grips to prevent any unwanted rotation. Turn the impeller counter-clockwise (when facing impeller) to remove and this will reveal the mechanical shaft seal. This seal can then be removed from the motor shaft for inspection. The motor bracket can be removed from the motor by removing the 4 bolts on the backside of the motor bracket. To remove the ceramic shaft seal, press gently from the backside on the ceramic and it will fall out easily. Inspect, clean or replace parts as needed.

C. Pump Assembly

Reassemble unit by first pressing the ceramic seal into the seal plate. Use rubbing alcohol as a lubricant. Do not use an oil, vaseline or grease as this will damage the sealing surfaces of the shaft seal during operation. Next, install the motor bracket onto the motor using the four bolts. Tighten the bolts in a diagonal pattern

to insure a proper fit. Place the shaft seal on the motor shaft and then install the impeller and eye-seal. The diffuser is positioned by three bolts that can only be installed when the diffuser is oriented properly (Figure 9). Position the diaphragm on the diffuser suction eye. (as shown in Figure 9). The grommet will slide over the diffuser eye on top of the diaphragm. Lift the motor assembly up into the pump case and attach it using the 4 bolts. When seating the pump case against the motor bracket, the diaphragm should be captivated between them around the entire perimeter. This allows the diaphragm to serve as a water seal between the two cast iron parts. If the diaphragm is not positioned correctly the unit will leak once the case is filled with water. Tighten all bolts to 185 in-lbs in a diagonal pattern to insure proper seating of all components.
