By detecting diaphragm pump failure and resulting material leakage a DFD kit helps eliminate costly production downtime






  • Cost-effective way to get your pumps wired for preventive maintenance

How ARO Diaphragm Failure Detection (DFD) Works:

  • A refractive infrared light sensor installed into the air side of the diaphragm housing sends and receives a continuous optic signal. If diaphragm failure occurs and fluid enters the air side, the sensor's beam is absorbed and an output signal is sent indicating failure.

When and Where to Use ARO DFD:

  • When pumping aggressive or hazardous materials that could pose a threat to the work environment
  • In remote locations where constant monitoring is critical
  • When pumping expensive materials
  • Where OSHA or EPA standards and codes require monitoring
