SNS range

Exceeding expectations: our record-breaking process pump range

The SNS end suction single stage pump range has been designed to exceed the highest energy efficiency regulations across all industries and also the design requirements of ISO 5199 international standard. The innovative design makes the pump more reliable while significantly reducing total cost of ownership.

SNS end suction single stage pump range
Main benefits
  • The SNS process pump range not only meets the ErP (Energy-related Products) criteria, but breaks all records by exceeding MEI 0.7 requirements (Minimum Efficiency Index) 
  • The highest efficiency on the process pump market providing clear savings in energy consumption
  • Highest hydraulic power on the process pump range. The SNS pump provides increased flow and a higher head than a conventional pump
  • Low energy consumption due to high efficiency
  • Low spare part costs due to high standardization
  • Low installation and maintenance costs due to easy installation and unique design
Main applications
  • Clean and slightly contaminated liquids

Applications
  • Industrial water and effluent treatment
    Sulzer has a deep knowledge in wastewater treatment, and with our wide product portfolio we can now offer energy-efficient and reliable solutions for your water collection, neutralization, flocculation, sedimentation, cooling, aeration, sludge storage, digestion, and dewatering processes.

  • Mining
    Whether on the surface or underground, the conditions in mines are harsh. Besides the mud, slurry, stones, and rocks, there are large volumes of water to remove in order to keep production moving. Our dewatering pumps are rugged and ready, taking on the toughest drainage and sludge removal.

  • Municipal clean water supply and distribution
    Getting drinking water to all parts of a distribution network involves many challenges along the way. From the water treatment plant through pumping stations and beyond, Sulzer pumps lift and move the drinking water to bring it to its destination at sufficient flow and pressure.

  • Municipal clean water treatment
    When planning new water treatment plants or upgrading existing ones, operating costs are as important as investment costs. Sulzer’s innovative pumps, mixers and compressors combine reliable treatment performance with superior energy efficiency.
