Advantages of reciprocating pump
(1) High exhaust pressure can be obtained, and the flow rate is independent of the pressure. The inhalation performance is good and the efficiency is high. The steam reciprocating pump can reach 80%~95%.
(2) In principle, any medium can be transported, almost free from the physical or chemical properties of the medium;
(3) The performance of the pump does not vary with the change of pressure and the viscosity of the conveying medium.
Other pumps do not have the above outstanding advantages of reciprocating pumps, but their structure is relatively simple, easy to use and operate, but also have the advantages of small size, light weight, uniform flow, and can be serialized batch production.
Shortcomings of reciprocating pump
Flow is not very stable. At the same flow rate, it is larger than centrifugal pump; the mechanism is complex; the amount of funds is large; it is not easy to maintain.
