Waterfall Pumps

Choose a waterfall pump for a pond, stream or pondless waterfall. The right pump delivers the required flow at the spillway after allowing for vertical lift and pipe resistance. Compare fixed-flow and adjustable models, and check whether the installation uses a submerged pump or an external pump.

Plan the flow at the waterfall spillway

Spillway width and the water effect you want determine the target flow. Measure the vertical rise from the water surface to the outlet, and account for the pipe run, bends, valves and any filter. Use that total head to compare pump curves.

Larger pipe can reduce friction losses, but the final pipe size must suit the selected pump and installation. A compatible adjustable-flow model lets you tune the display within its operating range. Plan access to the intake and any reservoir or pump vault for cleaning.

Compare Aquascape SLD adjustable pumps with AquaSurge pond and waterfall pumps. See pond filters and waterfall filtration for systems that also need debris removal and biological filtration.

Common questions

Is maximum GPH the flow at the top of my waterfall?

No. Delivered flow falls as head increases. Check the pump curve at the combined vertical lift and resistance of your plumbing and equipment.

Should I choose an adjustable waterfall pump?

An adjustable model can help fine-tune the display or circulation. It still needs to be sized for the required head and flow; a controller cannot make an undersized pump deliver beyond its performance range.
