Disassembly and Assembly
1. Disassembly
When disassembling pump, have a piece of cardboard or wooden board ready to place the
different parts on as you work. Do not pile parts on top of each other. They should be laid out
neatly in rows. The “O” ring and gasket cannot be used again once they are removed.
Have replacement parts ready. Disassemble in the following order, referring to the sectional view.
Be sure to turn off power source before starting disassembly.
(a) Remove pump casing bolts, raise the motor section, and remove pump casing.
(b) Remove shaft head bolt and impeller.
(c) Remove oil filler plug and drain lubricating oil.
(d) Remove intermediate casing bolts and intermediate oil chamber.
(Remember that any lubricating oil remaining in the mechanical seal chamber will flow out.)
(e) Carefully remove mechanical seal, taking care not to scratch sliding surface or motor shaft.
2. Assembly
Re-assemble in reverse order of disassembly.
(a) During re-assembly, rotate the impeller by hand and check for smooth rotation. If rotation is not
smooth, perform steps-(3) through -(5) again.
(b) Upon completion rotate the impeller by hand from the suction inlet and check that it rotates
smoothly.
Please obtain “O” rings, shaft seals and other parts from your dealer. Refer to part lists
attached.
