Designed and manufactured using the latest developments in magnetic technology. The pump consists of a power unit encased in water-proof epoxy which creates a magnetic field. This drives a powerful magnetic ceramic impeller, the only moving part, which makes it extremely energy efficient (over 50% savings compared to equivalent conventional pumps). These fish-safe magnetic pumps are virtually maintenance free with no seals to wear out. Sturdy construction from environmentally friendly plastic materials allow submerged operation in freshwater or saltwater.
