MBN high-pressure stage casing pumps
Multi-purpose solutions for all high-pressure needs
The MBN pumps are ideal for use in high-pressure applications. They have a big variety of nozzle position options, thus providing flexibility during installation and simplifying the piping design. The thrust bearing and shaft seal can be easily exchanged without disassembling the suction casing.
- Boiler feed duties in industrial power applications up to 180° C
- Condensate service in power stations and industrial plants
- Feed pumps in desalination by reverse osmosis
- Shower water in paper mills
- High-pressure water in general industry
