Nitrile fluid section kit for the 2 inch ARO PD20P-FPS-PGG pump, with Nitrile diaphragm and balls plus gasket, U-cup, O-ring and grease.
WHERE TO BUY?
For the PD20P-FPS-PGG, the ARO 637373-GG supplies Nitrile for both the diaphragm and the check balls. Nitrile, also called Buna-N, is a synthetic rubber. The notes describe it as a 2" diaphragm pump fluid section kit with a grease package, gasket, U-cup, O-ring, ball and diaphragm.
Having the diaphragm, balls and seals in one box means a single order covers the parts that flex and seat on every cycle. The grease helps the new U-cup and O-ring slide into place without tearing.
When to Use This Kit
- Rubber diaphragms look stretched, blistered or hardened at inspection time.
- The pump runs but loses prime between batches or after short stops.
- Air consumption rises while fluid delivery stays flat or falls.
