  • Pump Head vs Discharge Pressure (Easy explanation

    2017-8-10 · Whether you’re pumping water or a heavy caustic solution, the head achieved will be the same. The pressure at the discharge of the pump, however, will be higher for the heavier solution. That’s why we would not be able to do simply looking at a pressure gauge and figure out what is pump’s discharge head ability is.

  • Converting Pump Head to Pressure and Vice Versa

    2021-5-13 · Intuitively, if a pump can produce more pressure, it can pump water higher and produce a higher head. Also note that the higher the liquid in the tank, the higher the pump will be able to pump the water into the vertical discharge pipe, due to the head exerted by the liquid in the suction tank (see Figure 2).

  • Head | Pump Head and Shut-Off Head Pressure

    2010-10-13 · Pumps develop differential head, or differential pressure. This means the pump takes suction pressure, adds more pressure (the design pressure), and generates discharge pressure. So, the discharge pressure is equal to the suction pressure plus the pump’s design pressure. The discharge pressure of the pump should be approximately equivalent to the total …

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.
