12 GPM Air Operated Air Diaphragm Double Diaphragm Pump Cast Iron 115 PSI Dual Pump Petroleum Fluids 1/2 Inch Inlet/Outlet QBK-15

Superior Performance: Rugged construction designed to withstand high working pressures (115 PSI) to ensure reliable performance. With a maximum head of 164.04 ft and a maximum suction lift of 16.4 ft, fluid transfer tasks can be accomplished quickly Utility: Diaphragm pumps (also known as membrane pumps) are positive displacement pumps that use the reciprocating motion of rubber, thermoplastic, or PTFE diaphragms combined with appropriate valves on either side of the diaphragm (check valves, butterfly valves, flap valves, or any other form of globe valve) to pump fluids with increased efficiency Ease Of Use: Diaphragm pumps are designed with an external air distribution mechanism and a fully bolted structure to effectively avoid leakage. In addition, the sealed ball valve design provides easy access to the ball check valve and fluid cover for maintenance and repair Thoughtful Design: Equipped with a muffler to help reduce the noise of the product, thus improving the comfort of the working environment Safe To Use: The pump body adopts air power source design and pneumatic double diaphragm design, which will not generate heat and sparks when working, so it is safe to use. With self-protection function. Once overloaded, the diaphragm pump will stop automatically, and when the load returns to normal, it can start running automatically, Manufacturer: HHEMSTD
