MBN pumps

The MBN pumps are ideal for use in medium-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

• 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

MC pumps

MC-series pumps have a modular design thus allowing Sulzer to find the most efficient solution to meet customer requirements. Both investment costs and lifecycle costs are taken into consideration when designing the optimum pump and an optimized hydraulic design guarantees maximum efficiency.

 Main benefits

• Modular hydraulics for high efficiency in a wide range of operating conditions
• Large branch sizes for optimized inlet flow, low noise level and higher allowable forces and moments
• Unaffected by rapid temperature variations
• Easy access for cleaning to the seal cooling chambers
• Stiff shaft design for critical speeds above the maximum operating speed

 Main applications

• Main and auxiliary boiler feed duties up to 180° C
• Nitrogen Oxides (NOx) abatement and fuel injection in combined cycle
• Condensate service in power stations and industrial plants
• Auxiliary services within combined-cycle and industrial power plants
• Feed pumps in desalination by reverse osmosis
• High-pressure water in general industry
