ARO 637303-CC Hytrel Diaphragm Pump Repair Kit for PD30 Pumps

For ARO PD30 pumps with Hytrel wetted wear parts, the ARO 637303-CC supplies Hytrel diaphragms and Hytrel balls. The CC in the kit number matches the CC that appears near the end of each listed pump code, for example PD30A-AAS-CCC-C.

Its fit list includes both PD30A and PD30S model numbers. If your pump's code shows a different two-letter material pair, look at the other 637303 variants instead. The catalog gives the two materials but no component list for this kit.

Common Reasons to Rebuild

• Pumped product turns up at the muffler of a PD30 pump.
• Output has fallen off while the stroke rate climbs without matching flow.
• Ball checks chatter or stick, leaving the pump unable to hold its prime.
