Start with the flow you need at the outlet. Allow for the height the water must rise and the losses through pipes and fittings, then check the working point on the pump curve.
At 10m discharge head, Orange lists 70LPM with 4m of suction lift and 65LPM with 8m of suction lift.
See Orange’s suction performance table for other duty points
Three different measurements. The 10m discharge head sets the condition for the flow figures. Cut-in is the pressure at which the controller starts the pump. Maximum outlet height is the vertical rise from the controller to the highest tap or outlet.
The controller starts the pump when pressure falls to its cut-in setting and stops it when water stops flowing. It also stops the pump if it loses prime. The highest outlet should be no more than 13m above the controller.
Use mains power for the PressMatic controller. Orange excludes petrol and diesel generator operation.
