The diaphragm is hydraulically actuated. Its function is basically that of a partition. Hence, very high pumping pressures can be attained.
The diaphragm material is usually Teflon but also supplied in Stainless steel in some cases for extreme duty conditions & temperatures.
There is no leakage of the process fluid as it is hermetically sealed.
The diaphragm has a long life as it is always in hydraulic balance, with the liquid being pumped on one side, and process fluid on the opposite side.
The system is safe guarded by a built in relief valve on the hydraulic side, a diaphragm actuated compensating valve & Continuous Hydraulic oil venting system.
A rupture detection system is provided to detect diaphragm failure, in order to prevent the contamination of the metered fluid. The two diaphragms are marginally separated by a spacer, and are linked together by a light vacuum. In case of diaphragm failure the vacuum turns to pressure which is indicated by a compound gauge or switch. There is no intermediate fluid which virtually eliminates the possibilities of contamination of the pumped liquid.
The pumps are of glandless design eliminating all kinds of leakages.
