MBN multistage ring section pump

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.

Main benefits

Simple construction to minimize dimensions and reduce investment and maintenance costs High-quality investment cast impellers and diffusers for improved efficiency Fast and easy impeller mounting Bearing unit can be serviced without having to disassemble the pumps Wide range of materials available including duplex stainless steel grades

Main applications

Feed water supply in boiler plants Condensate supply in power stations and industrial plants Shower water in paper mills High pressure feed pump for desalination Industrial water and wastewater treatment

Main design features

Integrated diffusers and stage casings Product-lubricated Non-Drive End (NDE) bearing of innovative design Oil lubricated anti-friction bearing available for Non-Drive End (NDE) as option Balance drum and axial thrust bearing Keyless polygon shaft torque transmission for the impellers Shaft sealing only required in the low-pressure suction side
