Grundfos UPS Cast Iron Circulating Pumps

SKU: N/A Categories: ,

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.


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
