Lifan 162 water pump cover

A water pump is a machine that conveys or pressurizes liquids. It transfers the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport the liquid including water, oil, acid-base liquid, emulsion, suspended lotion and liquid metal.

Gas mixtures, and liquids containing suspended solids. The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency, etc; According to different working principles, it can be divided into positive displacement pump, vane pump and other types. The positive displacement pump uses the change of its working chamber volume to transfer energy; Vane pumps transfer energy through the interaction between rotating blades and water. There are centrifugal pumps, axial flow pumps and mixed flow pumps.
