From a storage tank
Describe the lowest water level relative to the pump and the inlet pipe route. Include the replenishment arrangement and low-water condition.
Pressure boosting
Water at the outlet.
At the pressure you need.
Describe where pressure is insufficient and which outlets operate together. The inlet conditions are just as important as the required delivery pressure.
Start a pressure brief
Understand the system
How pressure follows demand
In a matched variable-speed system, pressure feedback helps the pump respond as outlets open and close.
Water flow
Electrical power
Sensor signal
Demand changes
Opening an outlet changes the flow required from the water supply.
Pressure is measured
A compatible sensor reports the delivery pressure to the control system.
Pump speed responds
The matched drive adjusts motor speed to work towards the pressure setting, within the pump’s operating range.
A photo of the pump nameplate and a short description of the pressure problem are a useful starting point.
Define the task
Where does the booster get its water?
From an existing pressure source
Record the available pressure while water is flowing, where it was measured and how it varies. The installation arrangement must suit the local supply conditions.
For a useful recommendation
Separate the inlet
from the delivery target.
The pressure the pump needs to add depends on the available inlet pressure, the delivery elevation and system losses. An outlet pressure target on its own is not a complete pump duty.
Build a selection brief- Demand
- Simultaneous outlets, required total flow and changes throughout the day.
- Delivery target
- Pressure needed at the point of use and the highest delivery elevation.
- Inlet conditions
- Lowest operating inlet pressure or tank level, measurement point and pipework.
- Existing equipment
- Current pump, control, vessel and available electrical supply, if any.

Before you choose
A few useful
questions.
Should I choose from the pressure reading with taps closed?
Include readings under operating demand and identify the measurement location. A static pressure reading does not describe pressure during simultaneous use.
Is a bigger pump always the answer?
First describe the source, inlet restrictions, pipework and required duty. A different pump alone may not resolve limitations elsewhere in the installation.

starting point.
Browse the relevant families, or ask us to help narrow them down.
Start with the incoming supply and the pressure needed where the water is used.
These are product directions, not an automatic pump selection. We’ll confirm the duty, installation and electrical fit for the proposed model.
