...Aluminum Oxide Ceramic Impeller Shaft and Bearings insure long pump life because they are non-corrodible with hardness more than 3 times that of stainless steel. Epoxy Resin Encasement of key internal motor components prevents unwanted conductivity and corrosion of metal parts. This pump incorporates a magnetic wet-rotor design, so there is no seal to fail that would damage the pump motor..
EFFICIENT: Neodymium Iron Boron (NdFeB) Magnets are used in all our electric motors because they are the most powerful permanent magnetic materials commercially available and increase energy efficiency. Water-Lubricated Nitrile Bushings are used because they possess a very low coefficient of friction, have inherent vibration-dampening qualities and are non-polluting..
SAFE & EASY: Safe for fish with no exposed copper and oil free. Easy to clean with no tools required to disassemble and remove the impeller/rotor. Our waterproof SJTW Electric Cord has 18 gauge copper wire, molded plug with ground and a heavy duty flexible vinyl jacket which resists oil/grease/moisture/abrasion with very good flexibility at all temperatures..
SPECIFICATIONS: Salt or fresh water ready with flow Rates of 211 Gallons Per Hour (GPH) @ 0' Lift.
