Grundfos Pump Applications

Grundfos Boiler Pumps for hot water, steam & thermal oil boilers

Grundfos Hot Water Boiler Pumps

Grundfos boiler pumps and multistage pumps for hot water boilers are available for temperatures up to 140°C. All pumps can be supplied with motors with a wall-mounted or integrated frequency converter (up to 22 kW), ensuring that the pressure and temperature in the system are constant. If the boiler requires a shunt in order to avoid thermal stress, we offer highly reliable pump solutions that will hold the temperature in the boiler constant.

Grundfos Steam Boiler Pumps

Grundfos boiler pumps supplies unique feeding pumps for steam boilers that offer unsurpassed efficiency in a variety of industrial processes. Each multistage pump is capable of feeding the boiler between 0.5 and 180 m3 water per hour, and the volume is easily increased by applying more pumps.

Designed to withstand the high pressure, the high media and ambient temperatures and the significant number of starts and stops encountered in boiler applications, the pumps have been optimized in every aspect – and are even capable of efficiently handling poor inlet conditions. The pumps can further be supplied with an air-cooled top that protects the shaft seal from any damage caused by high temperatures.

Grundfos Thermal Oil Pumps

Thermal oil is a highly suitable – and safe – alternative to steam in many processes, particularly where the dangers of high pressure are to be avoided. The Grundfos range of feeding pumps for thermal oil applications handles temperatures up to 240°C.


grundfos ups pumps

     Grundfos UPS 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.


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.



grundfos magna3 pumps

                         Grundfos Magna3 Pumps                                           

The MAGNA3/UPE pumps make up a broad range of small, medium and large circulator pumps – all fitted with communication equipment and state-of-the-art motors. These high performance pumps are perfect for high performance building systems, and fit both heating and cooling applications.

MAGNA3 knows the perfect setting

With a MAGNA3, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting called AUTOADAPT. The MAGNA3 will now automatically analyse the heating system, find the optimum setting and then continuously adjust its operation to changes in demand. The result is optimum comfort and minimum energy consumption.


MAGNA3 pumps are extremely flexible and reliable, and have low noise levels, long life and no maintenance requirements. They are fitted with IR communication and can offer external control and monitoring via expansion modules.


The Grundfos MAGNA3 circulator pumps are designed for circulating liquids in the following systems:

  • Heating systems
  • Air-conditioning and cooling systems
  • Domestic hot-water systems.

The pump range can also be used in the following systems:

  • Ground source heat pump systems
  • Solar-heating systems.
