PUMP END ASSEMBLY
1. Clean and inspect all pump parts (0-ring, seal seats, motor shaft, etc.).
2. If replacing the seal, apply sealant in bracket bore hole and around seal case according to sealant instructions. We recommend using Gasgacinch
®
.
Silicone sealant can also be used.
3. Press seal into bracket while taking care not to damage seal face.
4. Place slinger (rubber washer) over motor shaft and mount bracket to motor.
5. If replacing the seal, carefully lubricate the boot around ceramic piece and press it into the impeller hub making certain that the ceramic is in evenly
— the sealing surface should be parallel with the impeller hub.
6. Apply clean water to the carbon-graphite and seal seat sealing surfaces. Do not use silicon lubricants or grease!
7. Mount bracket to motor face.
8. Thread impeller onto shaft and install o-ring and screw! 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. Place diffuser over impeller and tighten allen bolts used to hold diffuser in place. Note: Be sure diffuser is in an upright position. (The word “top”
appears on the diffuser as an indicator).
10. Seat O-ring on diffuser. Assemble diffuser to bracket with two allen screws.
11. Seat O-ring in bracket slot and assemble casing to bracket.
12. Install drain plugs with its O-rings in casing drain holes.
DISASSEMBLY
1. Shut off power to motor before disconnecting any electrical wiring.
2. Close all necessary valves on inlet and discharge lines and drain the pump by removing both drain plugs.
The water will drain faster if you loosen the lid.
3. Disassemble bracket-motor assembly from casing by removing the nuts and bolts. (The casing may be left in-
line)
4. Unscrew the two allen bolts and remove diffuser. Diffuser may need to be pried off with a flathead screwdriver.
5. Remove screw and O-ring from front side of impeller. Screw is a left-handed thread and loosens in a clockwise
direction.
6. Remove cap covering shaft at back of motor. Unscrew the impeller by twisting counter clockwise while holding
the shaft with a large screwdriver to prevent shaft rotation.
7. Remove ceramic piece from impeller (if replacing the seal).
8. Detach bracket from motor.
9. Remove seal from bracket by pressing out from the back (if replacing the seal). Do not dig out from the front!
