TABODD Air Operated Double Diaphragm Pump QBY-15Z 1/2 inch Outlet Inlet 12 GPM Pneumatic Transfer Pump 115 PSI Industrial Pump Pneumatic Double Diaphragm Pump for Chemical Waste Oil Cast Iron

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 to pump a fluid..
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..
EXCELLENT CONSTRUCTION - Resists corrosion for reliable performance and long life. Bolted construction is designed for leak-free fluid handling. Easy access to ball checks and fluid caps for maintenance and repairs..
VERSATILE USE - The diaphragm pump with convenient operating are widely used in various industries, such as petroleum, metallurgy, mining, coating material, printing, paper making, water treatment, automotive etc..
