ARO 637401-CC EXP Service Kit, Hytrel
Hytrel EXP service kit renewing diaphragms and balls on CC-coded ARO PD10 pumps
ARO 637401-CC is a Hytrel service kit for PD10A and PD10S EXP pumps. Both diaphragms and balls are Hytrel, and 10 pump models are listed.
Hytrel is the defining material of the ARO 637401-CC. This EXP service kit uses Hytrel diaphragms and Hytrel balls, matching PD10A and PD10S pumps whose model codes end in CC.
The fit list includes both PD10A and PD10S models, with codes ending in CCC or HCC. Hytrel is a thermoplastic polyester elastomer. Choosing the CC kit keeps a Hytrel-built pump on the same diaphragm and ball material after the rebuild, rather than mixing elastomers.
Common Reasons to Order
- Product is being pushed out of the air exhaust.
- The pump cycles but delivers little fluid.
- A planned overhaul of a CC-coded PD10 pump is coming up.
- Balls rattle or chatter and no longer seat cleanly.
