Circular Pumps
UPS pumps 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.
Applications
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
▪ Main pumps
▪ Zone pumps
▪ Boiler shunt pumps
▪ Pumps for heating surfaces
▪ Calorifiers
▪ Underfloor heating systems
▪ Solar heating systems
▪ Heat pump systems
▪ Geothermal heating systems
▪ Heat recovery systems
▪ Two-pipe air-conditioning systems
▪ Pumps for refrigeration units.
