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 Content1 x Air-Operated Double Diaphragm Pump QBK-151 x Product Manual

• 【Parameters】Maximum pressure 115PSI, maximum suction height 16 feet, maximum head 226 feet, 1/2 inch air inlet/outlet, 1/4 inch air inlet, maximum flow 12 GPM.
• 【Diaphragm Pump】A diaphragm pump is a positive displacement pump that combines the reciprocating action of a rubber, thermoplastic or PTFE diaphragm with appropriate valves on both sides of the diaphragm (check valve, butterfly valve, flap or any other form of stop Valve) to pump fluid.
• 【High-quality Cast Iron】The pneumatic double diaphragm pump is made of high-quality cast iron, which has good wear resistance, heat resistance and corrosion resistance, reliable performance and long service life.
• 【Easy Maintenance】The motor design can provide the best air efficiency, and the bolt structure can realize leakage-free fluid handling. Easy access to the ball valve and fluid cover for maintenance and repair.
• 【Application】Membrane pump adopts external gas distribution system, which is suitable for low-viscosity petroleum fluids, including diesel, kerosene, engine oil and some waste oil. It is widely used in petroleum, metallurgy, mining, coatings, printing, papermaking, water treatment, automobile and other industries.
