Hydraulic Actuated Diaphragm Pump

Function of Hydraulically Actuated Diaphragm Pump: A Hydraulically Actuated Diaphragm Pump is also called Hydraulically Flexed Diaphragm Pump. A pump that transmits power using operating oil (silicone oil, etc.) filled between a diaphragm and a piston that serves as the drive source.

The plunger moves in a closed sealed hydraulic chamber. The diaphragm is hermetically sealed between two metal parts on the other side of the plunger. The reciprocating movement of the plunger causes the movement of the diaphragm.

Suction Stroke: When the plunger moves backwards the diaphragm also moves backwards creating vacuum & discharge valve is closed & suction valve opens allowing liquid to enter into the chamber.

Discharge Stroke: When the plunger moves forwards the diaphragm moves forward creating Pressure & suction valve is close & discharge valve opens discharging fluid in the outlet pipe.

As the Diaphragm is tightly sealed between two solid parts, practically seals are not required to making this pump a seal less & zero leakage pump.

The hydraulic force acts uniformly on the diaphragm, these pumps have the ability to deliver against high pressure above 200 Kg./Cm.2g.

An inbuilt safety relief valve, in the hydraulic chamber, is standard future to protect the pump from over pressure.

Hermetically tight SR Make diaphragm pumps require no seals as the diaphragm is sealed between two solid parts. There is no possibility of external emission.

A special feature is available where diaphragm deterioration / rupture can be detected by visual indication using a pressure gauge. Alternatively, an electrical alarm signal of diaphragm failure/rupture can also be provided using a pressure switch / pressure transmitter.

Applications:

• Highly corrosive chemicals hazardous for fluid dosing
• Suitable for zero leakage is required.
• High pressures chemical dosing upto 180 Kg./Cm.2
