Specifically designed for the demands of a pond or aquarium, unlike most other pumps on the market. Magnetic drive pumps are made to run continuously, without seals to wear out. Highly energy efficient. Being filled with epoxy, not oil, they can not leak oil into the pond. All Mag Drive pumps are suitable for statuary, fountains, ponds, and/or aquariums. UL listed to U.S. and Canadian safety standards. Good for freshwater and saltwater aquariums. May be used in-line or submerged.
