【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.
