DESCRIPTION

UPS pumps constitute a 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.
