$265.100
ARO 637369 rebuilds the air section on PD20 and PD30 diaphragm pumps, such as the PD20A-AAP-AAA-B and PD30A-AAP-AAA-C, across 133 models.
WHERE TO BUY?
Owners of ARO PD20 and PD30 diaphragm pumps turn to the 637369 when the air side needs a rebuild. Sample fits include the PD20A-AAP-AAA-B, the PD30A-AAP-AAA-C and several PD20P-FPS and PD20P-FKS builds. The air section controls how drive air alternates between the two diaphragms, so worn seals there show up as poor shifting rather than a fluid leak. No contents or materials are given in the record; match the kit number to the parts list for your pump. Read the series from the nameplate first, because PD20 and PD30 models share this list.
When to Use This Kit
- A PD20 or PD30 pump hesitates at the end of each stroke.
- Air consumption rises while fluid output stays flat or drops.
- The pump fails to restart after sitting idle under air pressure.
