1. High efficiency and wide area.
2. High pressure of high pressure reciprocating pump.
3. Capable of self-priming, conveying liquid and gas mixture, specially designed for conveying mud, concrete and so on.
4. The flow and pressure have a large pulsation, especially the single-acting pump, because of the acceleration of the piston movement and the discontinuity of the liquid, the pulsation is greater.
5. Low speed, large size, complicated structure, special pump valve, high manufacturing cost and installation cost.
