Comet P40 Group Body Kit 1204.0712.00, Old Unloader/Bypass

The Comet 1204.0712.00 group body kit rebuilds the old-style unloader/bypass on the original Comet P40 soft-wash pump (breakdown #102). Use it when the bypass body is cracked, leaking or no longer holding pressure steady.

This part is for the original (old-design) Comet P40 diaphragm pump. 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 and position number 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.
