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 requires a minimum natural flow to activate, it will then assist and improve a natural flow of water.

Positive head pumps use a flow sensor to monitor the natural flow of water (without the pump) passing through the system. 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.
