Factors that Determine Booster Pump Power, Flow and Pressure

28 Nov

A booster pump is no more than a pump, which may or may not come with a bladder tank, that lets you adjust domestic water pressure when demand is excessive. If you have a pool, it can be good to operate at relatively high pressure, with automatic cleaners and other robots being better at eliminating encrusted dirt.

 You may want to get a swimming pool booster pump for your system from envirosep.com. But what are the factors that determine power, flow and pressure for a booster pump?


Pressure is the force of the water at the discharge point in B (bars), and this depends on pump pipe cross-section. Manufacturers may also indicate pressure in CMW (column metres of water).

Pressure is flow's best friend. This is a basic law of hydraulics: for a specific flow, a larger-section pipe is going to produce lower pressure than a smaller-section.

Discharge height

The unit used to express discharge height is CMW. It's a critical criterion as you must ensure that the pumped water actually reaches the target discharge point. Surface pump manufacturing companies often report a discharge height (the difference in level between pump and discharge point) or a TMH (the total manometric height expressed in metres).


Flow is the core technical characteristic of a water systems. The flow rate refers to how much water is pumped as a function of time.

When choosing a pump, keep in mind though that flow rate will vary on the basis of suction depth and the discharge height. For a particular diameter of pump pipe, the same pump will create less flow as the height difference goes up.

On the other hand, the shorter the height between your suction and discharge points , the greater the flow rate. 250m3/h for each additional user. 5m3/h for 800m?. 

Domestic water pressure that is considered "comfortable" is anywhere from 2 to 3 B, depending on distance from the water tower or reservoir. In other words, remote, "end of the line" properties may deal with low pressure and find a booster useful. More facts about this company here!

If you get water from a well, look at the suction depth as well as the type of water you're sucking up. Look at discharge height too, which is the distance from the surface pump to the water distribution site - as when you water a garden that lies high above the well. Those who use an automatic watering system should take time to determine their required flow. Of course, more watering points mean more water required.
