MBN-RO Multistage Ring Section Pumps

• Top of its class efficiency to ensure lowest specific power consumption per produced cubic meter of water.
• Different hydraulics can be fitted in the same pump frame, allowing flexibility and modularity and allowing future retrofitting
• All parts typically subject to maintenance (both DE & NDE bearings, balancing disc, mechanical seal) are accessible and can be replaced on site, without removal of suction and discharge piping

Main applications

• High Pressure Membrane feed in Sea Water Reverse Osmosis applications.
• Clean Water Pumping Stations
• Any other high pressure application with clean liquids and low temperature

Main design features

• High efficiency, low NPSH impellers to match customer needs are used for all stages, providing modularity, top efficiency and ideal suction performance
• Double volute a last stage reduces the radial thrust and increases overall efficiency
• Replaceable stationary PEEK wear parts used to increase efficiency and reduce main­tenance
• Product lubricated bearing at both DE and NDE to make the pump compact, reliable and easy to maintain
• Balance disc at NDE as balancing device ensures optimum efficiency
• Radial suction flange allows accessibility to mechanical seal and product lubricated bearing at DE without disassembling the pip­ing
• Flanges can be installed side or top position as per customer convenience, ensuring typically side-side orientation
• Integrated single mechanical seal with flushing from first stage.
