Circulator Pumps

Grundfos Circulator Pumps

Grundfos circulators are available in a wide range of materials and configurations to meet your application needs. They are suitable for heating, cooling and hot water recirculation in residential and commercial buildings. 

Grundfos offers a full line of maintenance-free circulators for moving hot water, from the boiler to heating devices. Energy-efficient options feature a permanent magnet motor capable of saving up to 80 percent of energy consumption when compared with conventional circulators.

Available for both new home construction, as well as retrofit projects, Grundfos hot water recirculation solutions eliminate the wait for hot water at showerheads and sink taps, preventing thousands of gallons of water from flowing down the drain as it warms.

Grundfos Circulator 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.
