Introduction To Water Pump

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