What does the pressure rating of a pump mean?

All of the pumps available at Salamander Pumps are rated in ‘bar’, which is the measure of pressure – 1 bar pressure being equal to 10 metres static head of water (the pressure exerted by 10 metres of water).

The higher the bar rating, the higher the pressure. The following is a general guide for applications:

1.5 bar pressure for one shower, tap or appliance
2.0 bar pressure for two or three showers, taps or appliances or a bathroom
3.0 bar pressure for the whole house.
