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.➤Package Content:1 x Air-Operated Double Diaphragm Pump QBK-151 x Product Manual

【AIR-OPERATED DOUBLE DIAPHRAGM PUMP】 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.
