Cal Pump Direct Drive Waterfall Pumps are powerful, efficient pumps that stand up to the rigors of pumping high volumes of water at maximum head heights. Constructed with non-corrosive components and a ceramic mechanical seal, these water-cooled pumps ensure safe, efficient, and continuous operation without fear of harm to ornamental fish or aquatic plants. As these submersible pumps are sealed, not oil filled, they cannot leak oil into the pond, which can be harmful or fatal to fish and plants. Cal Pump Direct Drive Waterfall Pumps are rugged pumps built with heavy-duty motor shaft ball bearings and non-corrosive materials for longevity.

The sound and vision of a waterfall cascading down rocks into a pond or stream enhances a pond or water garden in a way no other water feature can. This Cal Pump Direct Drive Waterfall Pump is ideally suited for creating a waterfall that will further benefit your pond by oxygenating the water as it returns to the basin. This pump features a 0.50 Hp direct drive motor capable of turning 4900 gph at 1 ft. This pump accepts a male 1.25", female 1.25", female 1", or female 2" NPT threaded fitting or a 1.25" flexible PVC hose directly using the barbed adapter. Add a Plastic Prefilter Screen to elevate the pump from the debris on the bottom of the water feature. This hardy pump is perfect for powering a waterfall, biofilter, or stream in your backyard water feature. Six month warranty.

Pump Performance:
Use this chart to determine the proper size pump for your pond. The height of the water outlet above the surface of the pond is called the Head Height. Gallons Per Hour (GPH) represents the maximum amount of water your pump is capable of pushing at a given Head Height. To ensure the pump's best possible performance, reduce frictional losses by using the largest diameter hose possible.
