Air-Operated Double Diaphragm Pump 1" Inlet/Outlet - Heavy Duty Chemical Transfer Pump for Strong Acids, Alkalis & Corrosive Fluids (22GPM Flow Rate) | Ideal for Industrial, Wastewater Treatment & Hazardous Material Handling

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.
