Description
The Grundfos UPS43-100SF is a three-speed canned rotor circulator pump designed for hot water circulation and hydronic heating systems. The pump and motor form an integral unit without a shaft seal, using only two gaskets for sealing, while bearings are lubricated by the pumped liquid for maintenance-free operation.
