ARO 67350-1 Cycle Counter Kit

The -1 suffix sets this cycle counter apart: its listed fits run to PD20 and PD30 pumps, including PD30A and PD30S builds and the PD20A-AAP-AAA-B. Fitted to a pump, a cycle counter keeps a running total of strokes. Teams use that number to time diaphragm and check valve service by real use, or to compare pump effort between shifts. An instruction sheet is filed with this kit, though the record lists no contents or materials. Read the full number, including the -1 suffix, from your parts list before ordering.

When to Use This Kit

• A PD30 pump wears through diaphragms on no predictable schedule.
• Your maintenance system tracks equipment by run count rather than hours.
• You need a record of how many strokes a transfer took.
