Grundfos- UP-UPS Circulator pumps

 

 

Overview

Grundfos-UPS-UPAUPS 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.

 

Features and benefits

  • UP-UPS-CurveMaintenance-free
  • Low noise
  • Low energy
  • Complete range
  • Available with corrosion-resistant stainless steel or bronze pump housing
  • Wide range of accessories.
