Pump Overhaul
This section provides instructions for overhauling the P-1 or P-2 pump by replacing the internal
components. A pump should be overhauled if its flow rate has noticeably decreased, or if inspection of
the pump during disassembly for some other maintenance task (such as engine/motor replacement)
shows that the impeller or wear plate is damaged or badly corroded. Additional instructions in this
section describe how to replace the pump inlet flapper assembly and the outlet flange gasket.
NOTE
Whenever the P-1 or P-2 pump is disassembled for any of the maintenance tasks in
this work package, replace the drive sleeve, seal seat, seal assembly, and housing
gasket regardless of their condition. These components are included in the seal
repair kit. The overhaul kit includes these components plus the impeller, wear
plate, and wear plate mounting screws and gaskets.
