Double-Diaphragm Leak Detection

Neptune offers a double-diaphragm leak detection option for applications where contamination of the process fluid by the pump hydraulic fluid cannot be tolerated or where diaphragm failure must be sensed immediately.

The Neptune double diaphragm design uses two “dry” coupled diaphragms. The area between the diaphragms is sealed. Hydraulic pumping action is transmitted from one diaphragm to the other without the use of any intermediate fluids.

The diaphragm condition is monitored by a pressure switch which can be wired to shut off the pump and/or sound a remote alarm. This design eliminates conductivity probes which could fail to detect the presence of oil or low conductivity liquids in the event of a diaphragm failure.
