assembled improperly, it may lead to abnormal operation, electrical shock or water damage.
7. Disassembly and reassembly procedure
7.1 Disassembly
When disassembling the 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 exploded view drawings.
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.
7.2 Assembly
Re-assemble in reverse order of disassembly.
Be careful of the following points:
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 of re-assembly, 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.
