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 cut off power source before disassembly.
(1)
Remove pump casing bolts, raise the motor section and remove pump casing.
(2)
Remove shaft head bolt and impeller.
(3)
Remove oil filler plug and drain lubricating oil.
(4)
Remove intermediate casing bolts and oil chamber.
(Remember that any lubricating oil remaining in the mechanical seal chamber will flow out.)
(5)
Carefully remove mechanical seal, beware of not to scratch sliding surface of motor shaft.
2.
Assembly-
Re-assemble in reverse order of disassembly.
Be careful of the following points.
(a)

perform steps-(3) through -(5) again.

Upon completion of re-assembly step -(1) rotate the impeller by hand from the suction inlet and check that it
rotates smoothly without touching the suction cover before operating the pump.
Please order “O” rings, packing, shaft seals and other parts from your dealer.
