Sulzer has launched the new innovative SNS end suction single stage process pump range.

It is designed to exceed the highest standards of performance and reliability, and also the design requirements of the ISO5199 standard. For the customers this means substantial savings in total life-cycle costs and a reduced environmental footprint.

The new pump range was developed for pumping applications in the pulp and paper, water and wastewater, chemical processing, power, oil and gas, hydrocarbon processing, and general industries.

The SNS process pumps are designed to pump clean and slightly contaminated liquids, viscose liquids, and fibrous slurries. The unique hydraulic design ensures efficient pumping with a low NPSHr (net positive suction head required) across the whole pump range.

Improved reliability

State-of-the-art simulation technology was used for designing the reliable and highly efficient impeller, casing, and shaft sealing. This resulted in very efficient hydraulics with improved shaft sealing conditions to ensure high reliability. Optimised patent-pending balancing holes in the impeller together with a new design for the sealing chamber guarantee ideal conditions for maximising the lifetime of the seal.

Minimised total cost of ownership (TCO)

The innovative patent-pending Sulzer mechanical shaft seal solution provides easy assembly and maintenance. At the same time, it reduces the total cost of ownership by cutting down operation, maintenance, and downtime costs to a minimum. The compact pump design minimises shaft deflection and extends the shaft seal lifetime while decreasing unexpected shutdowns and overall maintenance costs.

Sulzer’s heavy-duty, rigid, and compact bearing units are leakage-free, which minimises unexpected shutdowns and reduces the maintenance costs. Standardized base plate, back pull-out design and flexible spacer coupling with an electric motor of standard feet make the installation quick and easy, thus bringing down the installation cost.
