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
Allow for separate controls if the pump needs to start and stop automatically.
Fill the pump casing and suction line with clean water before starting. Keep suction joints airtight. Fit a foot valve at the intake for suction lift or a long suction line, following Orange’s installation instructions.
