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.
