Which pump is more suitable for an application where very high pressure is required to be developed at moderate discharge?

A Reciprocating pump
B Centrifugal pump
C Turbine
D None of the mentioned

Correct Answer: Reciprocating pump

Reciprocating pumps are generally designed to pump in low flow, high head applications. One of the most extreme of these applications is water jet cutting, where only a few gallons pass through the pump per minute, but exceed pressures of 10,000 PSI.
