• 【Parameters】: Inlet Port: 1/2 inch (12.7 mm), Outlet Port: 1/2 inch (12.7 mm), Air Inlet Size: 1/4 inch (6.35 mm), Gas Nozzle: 0.32 inch (8 mm), Max Flow Rate: 2 m3/h (12 GPM), Suction: 0-5 m (0-16.4 ft), Max Head: 69 m (226.4 ft), Max PSI: 115 psi 【Excellent Reliability】: 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 【Professional Designs】: Bolted construction for leak-free fluid handling. Motor design delivers optimum air efficiency.” Unbalanced” air valve ensures no-stall operation. Easy access to ball checks and fluid caps for maintenance and repairs.
