  • Piston Pump Discharge Pressure - Pump engineering -

    2014-1-13 · During functional test, we started pump A and automatically stop the pump when it reached 6000 psi pressure. We put check valve on discharge line and pressure gauge to monitor the pressure. but we also install pressure gauge between check valve and pump discharge (this is for maintenance purpose when Operator wants to test the pump without shutting down the well).

  • Piston Pump - an overview | ScienceDirect Topics

    2016-3-16 · The mechanical vibration of the swash plate and the discharge pressure pulsation are both inherent characteristics of the piston pump. Many previous investigations focused on one factor alone. However, in reality the two factors affect each other, the FSIs cannot be ignored in a dynamic analysis of the pressure pulsation and the swash plate vibration of the piston pump.

  • The Advantages & Disadvantages of a Piston Pump |

    A piston pump uses the reciprocating motion of a piston rod to move fluid along an axis through a cylinder-shaped chamber. As the piston moves through the cylinder, pressure builds up and forces the fluid through the pump. The fluid flowing through the pump pulsates due to the movement of the piston through the cylinder.
