Air Operated Double Diaphragm Transfer Pump 1/2" 13GPM Max.100PSI Polypropylene Description 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. Superiority： 1. Good abrasion resistance, chemical resistance, and heat resistance. 2. Environmentally Sound: Bolted construction for leak-free fluid handling. 3. Efficiency: Motor design delivers optimum air efficiency. 4. Reliability: "Unbalanced" air valve ensures no-stall operation. 5. Versatility: Multiple porting options for your application needs. 6. Serviceability: Easy access to ball checks and fluid caps for maintenance and repairs. Application： 1. Perfect for use with water. 2. Suitable for general acid and alkali (not suitable for solvent). 3. Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil. 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.
