Exceeding expectations: the 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.

The innovative design means higher efficiency that translates to lower energy consumption. Coupled with this, high standardization, easy installation and unique construction also equate to lower maintenance and operating costs.

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.
