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 (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

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.
