Cal Pump Magnetic Waterfall Pump, 4100 gph
Cal Pump magnetic drive pumps are efficient, low-energy pumps that are built to meet the needs of a pond. Magnetic drive pumps are designed to run continuously without oil or seals that may fail. Because there is no oil, there is no danger of this pump leaking oil into the pond, which can be harmful or fatal to fish and plants. Using less energy than their direct drive counterparts, magnetic drive pumps can often save enough money in energy to pay for themselves in just one season. Cal Pump magnetic drive pumps are low maintenance with only one moving part, a shaft with impeller. Their durable construction, corrosion resistance, and energy efficiency will make a Cal Pump magnetic drive pump an integral part of your pond system season after season.

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 Magnetic 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 1/6 hp magnetic drive motor capable of turning 3950 gph at 1 ft. This pump accepts a male 1.5" NPT threaded fitting. 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. One year 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.
