By detecting diaphragm pump failure and resulting material leakage a DFD kit helps eliminate costly production downtime
FeaturesCost-effective way to get your pumps wired for preventive maintenance How ARO Diaphragm Failure Detection (DFD) WorksA 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 DFDWhen pumping aggressive or hazardous materials that could pose a threat to the work environmentIn remote locations where constant monitoring is criticalWhen pumping expensive materialsWhere OSHA or EPA standards and codes require monitoring Models672371", 1½", 2" & 3" Metallic EXP Pumps67236-1For 1-1/2” Metallic Diaphragm Pumps with Cast Iron or Stainless Steel center bodies67236-2For 2” and 3” Metallic Diaphragm Pumps with Cast Iron or Stainless Steel center bodies
