High efficiency and wide efficiency. To achieve high pressure, pressure changes almost do not affect the flow, and thus can provide a constant flow. It has the ability of self absorption, can transport liquid and gas mixture, specially designed, can also transport mud, concrete and so on. There is a big fluctuation of flow rate and pressure, especially for single acting pump, because of the acceleration of piston motion and the interruption of liquid discharge, the pulsation is greater. It is usually necessary to set up the air chamber on the discharge line (and sometimes on the suction line) to make the flow more uniform. Dual action pumps and multi cylinder pumps can also significantly improve flow unevenness. Low speed, large size, complex structure, centrifugal pump, special pump valve is needed, and the manufacturing cost and installation cost are higher. Piston pump is mainly used for water supply, manual piston pump is a widely used family life pump. The plunger pump is used to supply high pressure liquid source, such as the high pressure water supply of water press, it and piston pump can be used as drilling mud pump and oil well pump in oil field. Diaphragm pumps are especially suited for the delivery of highly toxic, radioactive, corrosive liquids, precious liquids, and liquids containing gravelly solids. The diaphragm pump and the plunger pump can also be used as metering pumps.
