Grundfos UPS circulator pump constitute a complete range of 3-speed circulator pumps, available both in 50 and 60 Hz.
The pumps can be used in both open and closed systems. UPS pumps are of the canned-rotor type, i.e. pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. UPS pumps are designed for circulation of liquids in heating and air-conditioning systems. Pumps with bronze or stainless steel housings are also suitable for use in hot-water service systems.
Examples of typical applications are:
One- and two-pipe heating systems
Boiler shunt pumps
Pumps for heating surfaces
Underfloor heating systems
Solar heating systems
Heat pump systems
Geothermal heating systems
Heat recovery systems
Two-pipe air-conditioning systems
Pumps for refrigeration units.
