UP53-46BF wet-rotor, bronze circulator pump with 1-1/2" flanged connection and a 3/4 HP, 115/230v, single phase, 1-speed motor for hydronic heating and cooling in closed loop systems. It has a flow range of 0-98 GPM and a head range of 0-37 feet. Flange gaskets are included, but flanges are sold separately. Grundfos UP Series pumps feature a canned rotor design in which the pump and rotor form an integral unit without a shaft seal to provide long life, excellent performance, and quiet operation. Internally lubricated bearings eliminate frequent lubrication. The UP Series' impeller is made out of corrosive-resistant, non-metallic material.
