2. Produs terminatview
The Grundfos UPS 50-80/2 F 200 Series Circulator Pump is a canned rotor type pump, designed for circulating liquids in heating and air-conditioning systems. The pump and motor form an integral unit without a shaft seal, with the bearings lubricated by the pumped liquid. This design minimizes maintenance and simplifies disposal. Key features include a 3-speed motor, ceramic radial bearings, carbon axial bearings, a stainless steel rotor can, bearing plate, and rotor cladding, an aluminum alloy stator housing, and a cast iron pump housing. The stator includes a built-in thermal switch for protection. The motor is a 1-phase motor, and the pump is supplied with a standard module in the terminal box for connection to the main supply via an external contactor.
