Pump
End Assembly
1.
Inspect all pump parts (O-ring, O-ring groove, impeller hub ID,
motor shaft, etc.) and clean if necessary.
2.
Apply sealant to the bracket bore ID wall and around the seal
case - follow sealant mfg. instructions. We recommend using
Gasgacinch®.
3.
Press the carbon graphite seal member into the bracket while
taking care not to touch or damage the carbon graphite face.
Never touch or apply pressure to the carbon graphite seal face!
4.
Screw the four M-Bolts, five complete turns into the threaded
holes located on the motor face.
5.
Mount the bracket to the motor by aligning the key holes over
each bolt head, then rotate cock-wise which will position the
small key hole slot under each bolt head. Tighten each bolt with
a wrench to secure the bracket to the motor (08 - 25 lb. in.).
6.
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.
7.
Apply clean water to the carbon-graphite and seal seat sealing
surfaces. Do not use silicon lubricants or grease!
8.
Lock the shaft by placing a screwdriver blade into the shaft
slot at the fan end of the motor. Thread the impeller onto the
motor shaft (Insure that the small impeller washer is in place
on the impeller). Thread until the washer securely contacts the
shaft shoulder.
9.
Seat the large O-ring into the bracket O-ring groove.
10.
Assemble the volute onto the bracket with six P-Bolts (10-24 x 2
3/4" carriage bolts) and six flanged lock nuts. Tighten in
a cross pattern (30 lb. in.).
11.
Install the drain plug and O-ring, into the volute drain hole.
12.
Before operating the Sequence® 750, allow a proper cure time
for the sealant used in steps 2 and 3. |
