Multi Stage Pumps
Grundfos Multistage Pumps are available as:
CM horizontal multistage and CR vertical multistage configurations.
The Grundfos CR vertical, multistage, centrifugal in-line pump family works for water supply, water treatment and almost any industrial solution – including those for high-pressure, hot, dangerous, flammable and aggressive liquids.

End Suction Pumps
Grundfos end-suction pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.
Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation.
The Grundfos NB/NBG pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The NB/NBG range consists of close-coupled pumps with their main dimensions in accordance with either EN733 or ISO2858.
Applications
Grundfos offers a virtually limitless range of close coupled (NB) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments such as the following:
- District heating plants
- Heating systems for blocks of flats
- Air-conditioning systems
- Cooling systems
- Wash down systems
- Other industrial systems.
Boosting Systems
The Grundfos SOLO and Hydro MPC booster systems are made to the very highest standards. Thanks to the CU 351 controller, they handle even the most difficult boosting jobs with ease and accuracy.
All components have been combined with focus on quality and efficiency. The Grundfos Hydro MPC booster systems are designed to last: sturdy, compact units with easy access to all service parts. Grundfos Hydro MPC booster systems can be used wherever additional pressure is required. Each booster model has been designed to meet specific customer demands for capacity and control.
The intelligent cascade control ensures that the optimum number of pumps required to meet the demand runs at any time. Together with the CR with IE3 motors, this makes the Hydro MPC the most energy-efficient solution for maintaining a constant pressure during changing flow demands.
Wastewater Pumps
Grundfos Wastewater Pumps
S pumps form the backbone of many sewage systems. They are selected for their strength, their durability, and for innovative features such as the SmartTrim impeller clearance adjustment system and the Smart Seal for leakage prevention.
The SmartTrim system used on the S-pumps makes it easy to adjust the factory-set impeller clearance and thus to maintain maximum pump efficiency.
The Grundfos SmartSeal Auto-coupling gasket provides a completely leak-proof connection between the pump and the base unit of the auto-coupling system. The shaft seal is capable of rotating in either direction. When the pumps are installed with separate pipework, sludge sedimentation can be avoided by back-flushing the system at regular intervals.
Applications
The pumps are suitable for the following applications:
- Transfer of unscreened raw sewage
- Transfer of raw water
- Pumping of water containing sludge
- Pumping of industrial effluent.
Dosing Pumps
Grundfos offers a wide range of dosing pumps representing state-of-the-art technology.
Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.
The DMH mechanical hydraulic dosing pump range is the preferred choice for industrial and complex tasks. The DMH range is a series of extremely strong, robust pumps for applications where a substantial dosing range and high-pressure capabilities are required.
