Waterfall Pump Selection

WATERCOURSE pump selection charts.

Which pump is right for your waterfall or stream?


These charts serve as recommendations for selecting the right pump for your watercourse (average watercourse application). In these calculations approx. 5 metres of a 1½" hose are used (with a pressure loss of approx. 0.15 head height).


Here is a rule of thumb for choosing the correct pump for a waterfall or stream
Width of  watercourse in cm x 1.5 litres / minute = Pump Flow Rate required in litres per minute.

so the wider your stream or waterfall, the larger pump flow rate required

Eg 50cm wide waterfall will require flow rate of 50 X 1.5 = 75 litres per hour required at the correct height.
