Discharge Pressure

Discharge pressure refers to the pressure of the fluid as it leaves a compressor, pump, or etc., and enters the system it is intended to supply.  When a pump is used to move a fluid, such as water or oil, it creates a flow by increasing the fluid's pressure.  The point at which the fluid exits the pump is known as the discharge point, and the pressure at this point is referred to as pump discharge pressure.

Discharge pressure is a parameter in various applications.  It determines the force with which the fluid is pushed into the system, and this pressure must be sufficient to overcome any resistance or head losses in the piping system and meet the requirements of the downstream processes or equipment.

Engineers and operators carefully monitor and control pump discharge pressure to ensure that it aligns with the specifications of the system, taking into account factors such as the desired flow rate, the height the fluid needs to be lifted (head), and any other resistances or losses in the system.  Proper control of pump discharge pressure is essential for the efficient and effective operation of fluid systems in various industries, including water supply, wastewater treatment, industrial processes, and more.
