The driving member in this pump is a flexible diaphragm. The advantage of this arrangement is elimination of all gland packings and seals which are exposed to the liquid being pumped. This is an important feature when used with hazardous, toxic or corrosive liquids.

Low capacity diaphragm pumps designed for metering service employs a plunger working in oil to actuate the diaphragm. Pumps of both single and double diaphragm can be offered. Diaphragm pumps with diaphragm rupture mechanism is also offered by us.
