Comet P40 Ordinary Maintenance Kit 5026.0419.00 / 10001-02078 (Fits Original & Current P40)

Comet part #5026.0419.00, also sold under Comet's updated part number 10001-02078 (schematic #105). Fits both the original and current Comet P40; only the collector changed between versions.

The Comet 5026.0419.00 / 10001-02078 ordinary maintenance kit covers the routine wear parts on the Comet P40 soft-wash pump: 3 diaphragms (1800.0088), 6 check valve assemblies (1220.0105) and 6 O-rings (1210.0506). Diaphragms and valves wear faster in bleach service, so many soft-wash crews rebuild on a set schedule rather than waiting for a failure.

This kit fits both the Original and Current Model Comet P40 three-diaphragm soft-wash pump (schematic #105). The valves are the same on both versions; only the collector system changed. The P40 is a common choice for soft-wash rigs, rated around 11 GPM at up to 300 PSI with chemical-resistant wet parts. Check the Comet P40 breakdown sheet to confirm the part for your pump before ordering.

Doing a planned rebuild with a complete kit gets the pump back to factory performance and saves the downtime of chasing one leak at a time. Follow the Comet breakdown when reassembling, torque fasteners evenly and run the pump with clean water to check for leaks before putting chemical back through it.
