Universal (Negative Head) Pumps

A universal (negative head) pump is suitable for systems where there is low or no natural flow.

These pumps pressurise the pipework between the pump and the outlet. When an outlet, like a tap or shower, is turned on, the pressure drops which a sensor in the pump recognises and activates the pump.

Positive Head Pumps

A positive head pump will assist and improve a natural flow of water, therefore, to be able to install a positive head pump a minimum flow rate is required.

Positive head pumps use a flow sensor to monitor the natural flow of water (without the pump) passing through the pump. When the flow sensor detects a flow rate on both hot and cold of at least 2 litre per minute the pump will turn on.
