    Maurice Stewart, in Surface Production Operations, 2019. 4.2.1 Pressure. Reciprocating pumps are constant volume pumps. Variations in discharge pressure do not affect flow rate. Since these pumps continue to deliver the same capacity, any attempt to throttle the discharge flow may overpressure the pump casing and/or discharge piping.

    Differential pressure. As the difference between outlet and inlet pressure increases, more fluid is forced back through the pump (increasing slip) and consequently the achievable flow rate is lower. This is the key factor in determining centrifugal pump efficiency since these do not have internal valves or gears to restrict backflow.
