Booster and pressure systems
Steady water pressure for buildings and sites, with the right number of pumps working at the right speed.
When water reaches the tap but not with any force
Low pressure on upper floors, taps that run weak at peak times and noisy pumps that start and stop all day are signs that the booster arrangement no longer fits the building.
A well-matched booster set runs only as many pumps as the moment needs and holds pressure steady while demand changes.
A multi-pump booster set
Change the demand and watch the pumps stage in and out.
Move the demand slider. The controller starts and stops pumps, and trims their speed, to keep the delivery pressure steady. Illustrative: the number of pumps and the pressure depend on the building.

What we ask about
What we look at and what we ask about so the recommendation fits your site, not a generic one.
- Number of floors and height to the highest outlet
- Peak demand and how it changes through the day
- Where the water comes from: municipal supply or a tank
- The existing pumps and controls
- How much downtime you can tolerate
- Noise limits and plant-room space
Match the pumps to the demand
Running several smaller pumps, with variable speed control, often matches a building's demand better than one large pump running flat out. It can also give you standby cover if one pump needs service.
- Staged pumps follow demand
- Variable speed holds pressure steady
- Standby cover during service

Frequently asked questions
Why is pressure low on the upper floors?
Usually the pump no longer matches the building's demand, or the supply is restricted. An assessment of the pump, pipework and controls shows which.
Do I need more than one pump?
Often yes. Two or more pumps give standby cover and let the system match demand more closely, which can reduce energy use.
Fixed or variable speed?
Variable speed holds pressure steadier and can save energy when demand changes. Fixed speed can be simpler where demand is constant. We recommend after looking at your site.
