  • Pump Head vs Discharge Pressure (Easy explanation

    2017-8-10 · Head is useful because it evaluates a pump’s capacity to do a job. If you have to pump a liquid up to 10m and your pump doesn’t have at least 10m of head, then there is no chance it will work. Your pump will need at least 10m plus the friction loss to get the required flow at the discharge point.

  • What Is Discharge Pressure? - Info Bloom

    2021-2-9 · A pump’s discharge pressure is generally determined by two main factors: pump strength and nozzle design. The strength of the motor within the pump determines the strength — stronger motors create higher pressures. The shape of the nozzle is the final factor; narrow and constricted nozzles create higher pressure than wide or open ones.

  • Discharge Pressure - an overview | ScienceDirect Topics

    Increasing discharge pressure for gas injection and decreasing suction pressure for gas gathering are two typical scenarios in which the flow point moves in the T direction. The speed of the compressor needs to be increased to keep up with the increasing pressure ratio. But the driver and compressor have their maximum speeds.
