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 pump performance include flow, suction, lift, shaft power, water power, efficiency, etc., according to different working principles can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy, while vane pumps use the interaction between rotating blades and water to transfer energy. There are centrifugal pumps, axial flow pumps and mixed flow pumps.
