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.FeaturesBrand new with top qualityAir-operated double diaphragm pumpWith 1 inch inlet and outlet1/2 Inch air inlet1/8 Inch max diameter suspended solidsPerfect for use with waterIdeal for use with low viscosity petroleum fluidsSolid constructionSpecificationsProduct: Diaphragm pumpType: Double diaphragmOperation Type: Air-operatedModel: QBY4-25LBody Material: AluminumInlet Port: 1 inch (25 mm)Outlet Port: 1 inch (25 mm)Air Inlet Size: NPT 1/2 inch (12.7 mm)Average Air Consumption: 38 CFMMax Flow Rate: 9 m3/h (35 GPM)Suction: 0-5 m (0-16.4 ft)Max Suspended Solids: 3 mm (1/8 inch)Max Head: 84 m (275.59 ft)Max PSI: 120 PSIMax Temp.: 150 ℉Self-Priming Dry: 3 m (10 ft)Self-Priming Wet: 4.6 m (15 ft)Manifold Connection: SingleValve Type: BallBall Material: AcetalCheck Seat Material: PolypropyleneDiaphragm Material: NitrilePackage Size: 35 x 26 x 23 cm (13.78 x 10.24 x 9.06 inch)Gross Weight: 9.86 kg (21.74 lbs)Package Includes1 x Air-Operated Double Diaphragm Pump1 x Product Manual
【Wide Applications】- Diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form shut-off valves) to pump a fluid. Perfect for use with water. Ideal for use with low viscosity petroleum fluids such as diesel, kerosene, motor oil and waste oil. 【Note】Can not used for corrosive liquid.
