ARO 66975 Cycle Counter Kit

The ARO 66975 is a cycle counter kit for ARO diaphragm pumps. A cycle counter records pump strokes, giving you a running tally you can use to plan service by usage instead of by calendar. The spec table lists no materials or dimensions for this kit.

Its fit list spans several sizes and body types: a 3/8 in. non-metallic PD03P model, 1 in. non-metallic and metallic pumps, and a 1-1/2 in. metallic pump.

Reasons to Add This Kit

• You want to log strokes to schedule diaphragm and ball changes.
• Batch transfers need a count to track how many cycles each job takes.
• An existing counter on a listed pump has stopped registering.
