PUMP END ASSEMBLY

1. Clean and inspect all pump parts (0-ring, seal seats, motor shaft, etc.).

2. Apply sealant to the bracket bore ID wall and around the seal case - follow sealant mfg. instructions. We recommend using Gas-

gacinch

. Silicone sealant can also be used.

3. Press carbon graphite seal into bracket while taking care not to damage carbon graphite face.

4. Place slinger (rubber washer) over motor shaft and mount bracket to motor.

5. Carefully, lubricate the seal seat elastomer OD and impeller hub ID with water. Press the seal seat into the impeller hub making certain

that the ceramic is in evenly — the sealing surface should be parallel with the impeller hub.

6. Carefully lubricate carbon-graphite and ceramic sealing surfaces with CLEAN water. Do not use silicon lubricants or grease!

7. Assemble bracket to motor with four M-bolts

8. Thread impeller onto shaft and tighten! If required, remove motor end-cap and use a screwdriver on the back of motor shaft to prevent

shaft rotation while tightening. Replace motor end cap.

9. Seat large O-ring in volute slot and assemble volute to bracket with seven 1/4-20 x 2

cross pattern (30 in-lbf).

10. Install drain plug with its O-ring in volute drain hole.

11. Before operating pump, allow a proper cure time for the sealant used in step 2.
