The water pump is a mechanical accessory that transports liquid or pressurizes the liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. The liquids mainly used for transporting include water, oil, acid and alkali liquid, emulsion, Suspension emulsions and liquid metals, etc.; can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters for judging the performance of the pump include flow rate, suction lift, head, shaft power, water power, and efficiency.
