Working Principle: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.Feature:Air-operated double diaphragm pumpWith 1-1/2 inch inlet and outlet2/5 Inch air inlet1/8 Inch max diameter suspended solidsPerfect for use with waterIdeal for use with low viscosity petroleum fluidsSolid constructionSpecifications:Product: Diaphragm pumpType: Air-operated double diaphragmModel: QBK_40LBody Material: Aluminum alloyInlet Port: 1-1/2 inch (40 mm)Outlet Port: 1-1/2 inch (40 mm)Air Inlet Size: NPT 2/5 inch (10 mm)Average Air Consumption: 9 CFMMax Flow rate: 10 m3/h (44 GPM)Suction: 0-5 m (0-16.4 ft)Max Suspended Solids: 3 mm (1/8 inch)Max Head: 69 m (226.38 ft)Max.

A diaphragm pump (Membrane 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 to pump a fluid.
The listing is about 44 GPM Air-Operated Double Diaphragm Pump with 1-1/2 Inch Inlet And Outlet. This powerful air-operated double diaphragm pump operates from 29 to 115 PSI.
Features a 1-1/2 in. inlet and 1-1/2 in. outlet capable of pumping up to 44 gallons/min at temperatures up to 80 degrees F.
Application - Perfect for use with water. Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil.
It works as it should. I have only pumped about 50 gallons so far but it worked well. The only thing I found wrong was there were a couple of bolts that were not tightened up when assembled.
