SNS end-suction single-stage process pump range

Exceeding expectations: our record-breaking process pump range

The SNS end-suction pump 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 this centrifugal pump more reliable while significantly reducing total cost of ownership.

Main benefits
  • The SNS process pump range not only meets the ErP 0.4 (Energy-related Products) criteria, but breaks all records by exceeding MEI 0.7 level (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

SNS end-suction process pumps are used in a wide variety of general and industrial applications to pump

  • clean and slightly contaminated liquids
  • viscous liquids
  • fibrous slurries
Main design features
  • Innovative, high efficiency, low NPSHr (Net Positive Suction Head required) impeller
  • Optimized shaft sealing chamber and innovative patent pending balancing holes guarantee ideal conditions for the shaft seal maximizing its life time
  • Innovative and reliable patent pending integrated Sulzer mechanical seals for trouble-free shaft sealing
  • Heavy-duty, rigid and compact bearing units with long bearing life and leakage-free construction

All pumps in the SNS end-suction process pump range have been standardized, using common modules and components. Fewer parts means greater process reliability and lower spare parts inventory costs.
