![]() The first step in the operation of a centrifugal pump is priming. However, a reciprocating pump can build up very high pressures as high as 69 x 106 N/m2 or even more and hence these pumps are used for lifting oil from very deep oil wells. But for a reciprocating pump, the maintenance cost is high because the parts such as valves etc. The maintenance cost of a centrifugal pump is low and only periodical checkup is sufficient. As such reciprocating pumps can be operated at low speeds only and for that these pumps are mostly belt driven. The maximum speed of a reciprocating pump is limited by the considerations of separation and cavitation. A centrifugal pump can be operated at very high speeds without any danger of separation and cavitation.Īs such it can be coupled directly through flanged coupling to the electric motor. But a reciprocating pump can handle only pure water or less viscous liquids free from impurities as otherwise, its valves may cause frequent trouble. The main advantage of a centrifugal pump is that its discharging capacity is very much greater than that of a reciprocating pump which can handle relatively small quantity of liquid only, A centrifugal pump can be used for lifting highly viscous liquids such as oils, muddy and sewage water, paper pulp, sugar molasses, chemicals etc. ![]()
