The Danner Supreme Mag-Drive Utility Pump is
specifically designed for statuary, fountains, ponds, and freshwater or
saltwater aquariums. It may be used either in-line or submerged. The
Mag-drive is extremely energy efficient and is designed to run
continuously. The pump consists of a power unit encased in water-proof
epoxy which creates a magnetic field. This drives a powerful ceramic
magnetic impeller, the only moving part. The pump contains no seals or
oil, and therefore is virtually maintenance free.
