Diaphragm Failure Detection (DFD)
Prevent Chemical Spills
Although it doesn’t happen often, diaphragm failure can occur. The DFD sensors will detect the chemical behind the diaphragm caused by diaphragm failure. The pump will then shut down and energize a relay switch. This permits communication with external equipment such as a backup pump, SCADA system, or alarm. It also serves to prevent chemical spills and added downtime.
