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. 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 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 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.
