the sliding surface of the mechanical seal (3). Remove the mechanical
seal (3) from the main shaft.

Reassembly Procedure
5.3.14 The reassembly procedure is the reverse sequence of disassembly.
Note: After completing reassembly, do not forget to pour the specified
amount of lubricant into the pump.
Note: The gaskets and O-rings must be replaced with new parts. Also
replace any parts that are worn or damaged.
5.3.15 Using a clean rag without lubricant, wipe the sliding surface of the
mechanical seal (3). Apply lubricant to the outer circumference of the
cushion rubber to facilitate insertion.
Note: For further details on how to install the mechanical seal (3), refer
to the “Mechanical Seal Handling Procedure” that comes with the
mechanical seal (3) that is sold separately as a spare part.
5.3.16 After installing the impeller (20), and after completing the reassembly,
check that the impeller (20) rotates smoothly and that it does not come
in contact with the suction cover (25).

operation before placing the pump back into service.
