Designed specifically for marine and industrial markets, this magnetically coupled centrifugal pumps is a good choice for applications that require a continuous-duty pump. Primarily used as marine air conditioner circulation pump, other applications include ice makers, hot water circulation, livewell or bait tank installations. Pumphead is manufactured from chemical-resistant thermo-plastics and is entirely non-metallic. Magnetic couplings provide an energy efficient thermal shield, minimizing heat transfer to the pumped fluid.Capacity: 21gpm; 11260gphSelf prime: 18'Fuse: 1.5ADimensions: 8 5/8"L x 4"W x 5 5/8"HPump Type: Continuous-duty magnetically coupled centrifugalVolts: 110V ACBest Use: Marine air conditioner water circulation and other continuous-duty pumping applications Ignition Protected: YesMaterial: Polypropylene housing, thermo-plastic pumphead, EPDM O-ring, polypropylene encapsulated magnet, PPS spindle housing, alumina ceramic spindlePort Sizes/Type: 1/2"NPTApprovals: CE and ULWarranty: One year
