Product Description
A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.
The listing is about 140 GPM Air-Operated Double Diaphragm Pump with 2 Inch Inlet And Outlet. This powerful air-operated double diaphragm pump QBY4-50L features a 2in. inlet and 2in. outlet capable of pumping up to 140 gallons/min at temperatures up to 150 degrees F.
Application
Perfect for use with water. Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil.
Warning!
Can not use for corrosive liquid.
Working Principle
In the pump two symmetrical working chamber each equipped with a diaphragm, the center link will be integrated into one. Compressed air from the pump inlet into the valve, through the valve body to introduce compressed air into one of the chamber to promote movement of the diaphragm chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison.
