Feature

●[Main Parameter]：Air Inlet Size: NPT 1/2 inch ; Max Flow Rate: 35GPM; Suction: 0-5 m (0-16.4 ft); Max Suspended Solids: 1/8 Inch; Max Temp.: 150 ℉; Max Head: 84 m (275.59 ft).
●[Working Principle 1]: 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.
●[Working Principle 2]: 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.
●[Application]: Perfect for use with water. Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil.
●[Premium Material]: Ball Material: Acetal; Check Seat Material: Polypropylene; Diaphragm Material: Nitrile
