A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.
It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, waterpower, efficiency, etc.; according to different working principles, it can be divided into positive displacement water pumps, vane pumps and other types. Positive displacement pumps use the change of the volume of their working chambers to transfer energy; vane pumps use the interaction between the rotating blades and water to transfer energy. There are centrifugal pumps, axial flow pumps and mixed flow pumps.
