Booster Pump Sets

Fixed speed with single Pump

A conventional pressure set provides on/off control using a pressure switch, with a vessel to provide some storage. The larger the pressure vessel that is used, the less frequently the pump switches on and off.

We offer these systems with a variety of pumps.

Variable speed with single pump

An advance on conventional on/off control uses a pressure transducer and inverter drive to vary the operating speed of the pump and provide a constant pressure system.

This provides a better control on the system with little or no variation in pressure.


Fixed speed with multiple pumps

Where demand is higher or variable, a dual pump system is used and conventionally this has been operated using a pressure set providing on/off control using pressure switches, with a vessel to provide some storage.

The switching pressures are set so that if one pump fails to meet demand the second pump will start and they can be used us duty/standy, where only one pump operates at any one time alternating to even wear, or duty/assist where two pumps are used if demand is high.

Larger units with more than two pumps can be assembled to meet demand.

We offer these systems with a variety of pumps.


Variable speed with multiple pumps

Considerable savings can be achieved if variable speed dual and larger units are used when the demand on the system is variable, eg in a holiday or residential complex.

The pressure transducer will measure the system pressure and increase the operating speed of the pump to meet demand. When the first pump reaches maximum speed the second will start and build up speed as required to maintain the pressure.
