MBN-RO multistage ring section pump
- 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
- 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
- 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
