ARO 67237 Diaphragm Failure Detection Kit

The ARO 67237 is a Diaphragm Failure Detection (DFD) kit for ARO (Ingersoll Rand) air-operated diaphragm pumps. A detection system of this kind exists to signal that a diaphragm has failed, so the pump can be shut down before process fluid travels into the air side or out through the exhaust. ARO files this kit with its Electronic Interface Accessories and Process Ready Pumps literature. The product record does not list kit contents or materials, so use those documents for components and installation steps.

When to Use This Kit

• A diaphragm rupture on this pump has already sent fluid out of the muffler or exhaust.
• The pump moves a fluid you cannot afford to release, and you want a warning instead of finding a leak on rounds.
• The pump is going into a monitored or automated line that needs a diaphragm failure signal.
