The Pondmaster Magnetic Drive Waterfall/ Skimmer Pump is ideally suited for pond skimmers and waterfalls. This completely submersible pump runs quietly and efficiently operating a waterfall or skimmer. Pondmaster magnetic drive pumps are designed to meet the demands of your pond and water garden. Unlike other pumps, magnetic drive pumps are made to run continuously, without seals to wear out. Magnetic drive pumps are energy efficient, using less energy than direct driven pumps, and may save hundreds of dollars over time. Being filled with epoxy, rather than oil, these pumps cannot leak oil into the pond, which can be harmful or fatal to fish and plants. These magnetic drive pumps are low-maintenance with only one moving part, a reliable ceramic shaft and impeller. ABS case, corrosion-proof fasteners, and heavy duty copper windings, resulting in a durable, energy-efficient, and long lasting pump.
