Factors Affecting the Power, Flow and Pressure of Booster Pumps

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. But what factors are considered in determining booster pump power, flow and pressure?


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

Pressure and flow are inseparable. This is a fundamental law of hydraulics: for a particular flow, a bigger-section pipe will produce less pressure compared to 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. Manufacturers of surface pumps typically report either a discharge height, which is the level difference between pump and discharge point, or a TMH, which is the total manometric height indicated in metres.


Flow is any water system’s key technical characteristic! The flow rate is the amount of water that is pumped per period 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 certain diameter of pump pipe, the same pump will bring less flow as the difference in height increases.

On the other hand, the shorter the height between your suction and discharge points , the greater the flow rate. If you’re using the surface pump at home, allocate no less than 2m3/h at the discharge point per five individuals, plus 0. 5m3/h for 800m?.

What is considered ‘comfortable’ domestic water pressure is around 2 to 3 B, depending on the distance to the water tower or reservoir. Hence, the most remote, “end of the line” properties may experience low pressure and find a booster helpful.

If you get water from a well, look at the suction depth as well as the type of water you’re sucking up. Pay attention to discharge height too i.e. the height of the surface pump relative to where the water is distributed – for example, if you plan to water a garden that lies high above the well. Those who use an automatic watering system should take time to determine their required flow. Obviously, you will need more water the more watering points you have.
