Sulzer MBN-RO Multistage Ring Section Pumps Brochure

The Heart of Your ProcessMBN-RO Multistage Ring Section PumpsSulzer Pumps2Sulzer Pumps is one of the world leaders in state-of-the-art pump-ing solutions. Combining engineer-ing and application expertise, our solutions add value and strength-en the competitive position of our customers. Thanks to a global network of manufacturing facilities, sales of-fices, service centers and repre-sentatives, we can provide fast responses to customer needs.Sulzer Pumps is a well-recognized player in the following industries:• Oil and Gas• Hydrocarbon Processing• Pulp and Paper• Power Generation• Water• General Industry• Chemical Process IndustryThe development of the MBN-RO pump is based on the existing Sulzer Pumps MBN ring section pump developed for the Power Generation, Water and Pulp and Paper industries. The MBN-RO fulfills the most stringent needs of a highly pressure pump and is particularly fit for the desalination market. Sulzer Pumps – Your Partner for Pumping SolutionsExtensive Knowhow in Reverse OsmosisKarhula, FinlandMBN-RO pump at Uramin SWRO plant, NamibiaMBN-RO Global Manufacturing Facility3The MBN-RO is a pre-engineered, ring section, multistage pump, specifically designed for high pres-sure membrane feed service in Sea Water Reverse Osmosis (SWRO) applications. Its improved hydraulic performance makes it suitable for any other high pressure application with clean liquids. Besides, by using improved, Duplex Materials The Duplex material is used for lower salinity water with lower Chloride content and / or with lower requirements regarding the Pitting Resistance Equivalent Number (PREN). According to Sulzer recom-mendations, the Duplex material is suitable for Chloride content up to 20,000 ppm, for temperatures lower than 40 °C and for a pH value from 6.5 -7.5. For lower pH, values, the according Chloride content limit will be lower.

Maintenance is also made easy with a quick and easy access to main wear parts such as mechani-cal seals or bearings without disas-sembling the suction and discharge nozzle. The MBN-RO range is manufactured in Duplex or Superduplex as standard materials for a variety of sea water qualities to avoid pitting and crevice corrosion.4MBN-RO Design Features and BenefitsBearing Assembly• 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 efficiencyHydraulics• 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 main-tenance5Flanges• Flanges can be installed side or top position as per customer convenience, ensuring typi-cally side-side orientation• Radial suction flange allows accessibility to mechanical seal and product lubricated bearing at DE without disassembling the pip-ingSeal Chambers• Intergrated single mechanical seal with flushing from first stageEasy Maintenance• 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 piping6MBN-RO Performance RangesOperating Data50 Hz60 HzHead H (m)1,000100101 10 100 1,000 10,000Capacity Q (m3/h)Head H (ft)10,0001,00010010 100 1,000 10,000Capacity Q (USgpm)50 Hz 60 HzPump sizes from 25 mm to 200 mm from 1 to 8 inchesCapacities up to 1,100 m3/h up to 4,800 USgpmHeads up to 900 m up 2,950 feetPressures up to 100 bar up to 1,450 psiTemperatures up to 90 °C up to 194 °F7Maintaining and Improving Pump PerformanceSulzer Pumps – Customer Support ServicesThe continuous availability and high operating performance of pumps is the key target for our customer support service organization.
