Description of Functioning: This is a Hydraulically Flexed Diaphragm Pump. The Plunger is moving in a closed sealed Hydraulic chamber. On the other side of Plunger a Diaphragm is Hermitically Sealed between two metal parts. The reciprocating movement of Plunger causes movement of 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 & Dischsrge Valve opens discharging Fluid in the outlet Pipe.
As the Diaphragm is Tightly Sealed between two Solid parts, Practically No Seals are required Making this Pump a SEAL LESS & ZERO LEAKAGE PUMP.
The Hydraulic force acts evenly upon Diaphragm these Pumps have capability of Delivering against High pressures above 200 Kg./Cm.2g.
Inbuilt Safety Relief Valve, in Hydraulic chamber, to Safeguards the Pump from overpressure is Standard future.
Hermetically tight SR Make Diaphragm pumps do not require any Seals as the Diaphragm is Tightly Sealed between two Solid parts. There is no possibility of Emissions outside.
As Special feature is available where Diaphragm Failure / rupture can be detected by Visual indication Using Pressure Gauge. Optionally an electrical alarm Signal of Diaphragm Failure / Rupture can also be provided by using Pressure Switch / Pressure Transmitter.
