Grundfos is the dominant force in the circulating pump market, covering 50% of the World market for these pumps.

End Suction Centrifugal

NB and NK are multi-purpose pumps suitable for a variety of different applications demanding reliable and cost-efficient supply.
NB and NK pumps are used in five main fields of application:

  • water supply
  • industrial pressure boosting
  • industrial liquid transfer
  • HVAC
  • irrigation.

Vertical Multistage

CR, CRI and CRN pumps are vertical multistage centrifugal pumps. The in-line design of the pumps enables installation in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal level and have the same pipe dimensions.

The design provides a more compact pump design and pipework.

Horizontal Multistage

The Grundfos CM is designed to be used in a variety of applications. These include:

  • Washing & cleaning
  • Temperature control
  • Water treatment
  • Chemical and Pharmaceutical industries
  • And more…


MTR, SPK and MTH pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications.

The pumps are designed to be mounted on top of tanks with the chamber stack immersed in the pumped liquid.

The pumps come in various pump sizes and have various numbers of stages to provide the flow, the pressure and the installation length required.


TP pumps are designed for applications such as

  • district heating systems
  • heating systems
  • air-conditioning systems
  • district cooling systems
  • water supply
  • industrial processes
  • industrial cooling.

The pumps are available with either mains-operated motors (TP and TPD) or electronically speed-controlled motors (TPE and TPED).


The pumps are installed in boreholes or wells, submerged below the water level.

For industrial purposes you can place the pump in e.g. a tank. The SP A and SP pumps are suitable for the following applications:

  • raw-water supply
  • irrigation
  • groundwater lowering
  • pressure boosting
  • fountain applications
  • mining applications
  • off-shore applications


Digital Dosing represents state-of-the-art technology. This patented Grundfos solution sets new standards, including new principles and methods.

Precise and easy setting The operator can easily install and set the pump to discharge exactly the quantity of dosing liquid required in the application.

In the display, the setting of the pump
is read out directly in ml/h or l/h, pulse or batch, and the operation mode is easily identified by means of icons.

Booster Sets

Our extensive range caters for every need; from ensuring the shower in a small cottage has sufficient pressure; to supplying the world’s tallest buildings with a constant and reliable water
supply. We have worked hard to earn our exceptional reputation for reliability and as a result have been entrusted to equip some of the country’s most iconic buildings. Our long list of high profile customers includes The Shard where water is needed 309 metres above the ground on the 72nd floor and Wimbledon which only operates at full capacity for two weeks of the year, though during these two weeks any pump failure would be catastrophic.
