High pressure demands can be fulfilled with a compact pump design (less stages) by operating at over-synchronous speed. Factory configured CRE's with reinforced chambers and impellers can be an option. The motor size must be adjusted accordingly.

Our variable frequency drives (VFD) can automate backwash through the use of sensors, so that no PLC is needed in simple filtration systems. The DDA FCM can accurately dose the right amount of chemicals so that the membranes are clean and protected, while the DID probes and controller can adjust the dosing pump based on changing water quality parameters.

1. Vertical multistage pumps - CR/CRE
Vertical, multistage centrifugal pump with suction and discharge ports on the same level.

2. Endsuction close coupled multistage pumps - CM/CME
CM, CME are reliable, quiet and compact horizontal end-suction pumps. The modular pump design makes it easy to make customised solutions.

3. Endsuction close coupled single-stage pumps - NB/NBE
End-suction close-coupled pumps according to EN 733. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework.

4. Endsuction long coupled single-stage pumps - NK/NKE
Standard pumps according to EN 733. The pump has an axial suction port, a radial discharge port and horizontal shaft. It is of the back pull-out design enabling removal of the coupling, bearing bracket and impeller without disturbing the motor, pump housing or pipework.

5. Endsuction long coupled single-stage pumps - NKG/NKGE
Standard pumps according to ISO 2858 with axial suction port, a radial discharge port and horizontal shaft. It is of the back pull-out design enabling removal of the coupling, bearing bracket and impeller without disturbing the motor, pump housing or pipework.

6. Horizontal multistage pumps - BM
High pressure booster modules are used for boosting, liquid transfer and circulation in systems under a high static pressure. Modules of different sizes can be combined and connected either in series or in parallel to meet exact Q/H requirements.

7. Horizontal multistage pumps - BMS
The Grundfos BMS range consists of hp (high pressure) and hs (high speed) versions. BMS hp are suitable for industrial and water supply applications where the inlet pressure is high. BMS hs enables the creation of high pressure.
