How to caculate a deep well pump head?

A suitable pump is selected suitably based on not only capacity but also head. So what is the pump head?

This is the vertical distance that you are able to pump the liquid. Say your pump is rated for a maximum head of 100 feet, this does not mean that you are restricted to100 feet of pipe, you could use 300 feet, so long as the final discharge point is not higher than 100 feet above the liquid being pumped.

 

There is a simple formula help you to caculate the deep well pump head when you are not exactly know the data of head.

Deep Well Pump Head = Dynamic warer level + Pressure at the outlet end of the pump(Mpa) * 100(m) + Pump (5 to 10 m)

 

- Static water level refers to the level of water in a well under normal, undisturbed, no-pumping conditions. 

- Dynamic warer level: In an well, the location of the liquid surface when the well is producing water. Also known as pumping level.

- Pressure at the outlet end of the pump: Discharge pressure (also called high side pressure or head pressure) is the pressure generated on the output side of a gas compressor in a refrigeration or air conditioning system.

- Head loss refers to the total pressure losses sustained by the fluid as it flows from the suction point to the discharge point. Head loss is caused when the liquid loses momentum as it flows, and depends upon fluid viscosity, pipe diameter, pipe length and accessories such as valves and elbows within the pipework.
