This powerful and efficient air operated diaphragm pump is perfect for all your needs in every industry!Warning!Working PrincipleIn 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.FeatureAir-operated double diaphragm pumpWith 1/2 inch inlet and outlet1/4 Inch air inletWith 0.32 inch gas nozzleGood abrasion resistance and heat resistanceServiceability and environmentally soundPerfect for use with waterIdeal for use with low viscosity petroleum fluidsWidely used in various industriesPackage Content1 x Air-Operated Double Diaphragm Pump QBK-151 x Product Manual
