We have large selection of waterfall pumps for water features of any size. These pumps can also be used for streams, pondless waterfalls, bogs and fountains.For small waterfalls, we recommend a minimum pump size of 1000 GPH (gallons per hour) to provide enough water flow to produce a pleasing look and sound. Medium sized waterfalls, that are wider or have a waterfall height, typically require a larger pump at least 3000 GPH. We also have high volume pumps that produce flows for waterfalls of any size. We carry energy efficient, magnetic drive, asynchronous drive, pumps from manufacturers such as Aquascape, PondMaster, Oase, PondMax, Easy Pro and Teton Dynamics
