Lubbock, Tex. — Xylem Inc., a leading global water technology company focused on addressing the world’s most challenging water issues, recently announced that its Goulds Water Technology and Bell & Gossett brand vertical turbine impellers will convert from their previous standard of silicon bronze to a new, high-grade investment cast 316 stainless steel (316SS) material. This change will mark the first product line available on the market with high-grade stainless steel impellers as a standard. 316SS is known for its enhanced ability to resist damage due to corrosion and abrasives.
The scope of the transition includes 5” through 14” models in select, high-volume product families. The smooth surface finish of these new impellers enables Xylem to make this material transition, without incurring additional hydraulic losses commonly associated with changing to stainless steel, while maintaining the same hydraulic performance standards as their predecessors.
“This conversion enables Xylem to offer a better corrosion- and erosion-resistant product than those currently available, without sacrificing efficiency or charging a premium,” said David Stover, marketing development manager, turbine products for Xylem’s Applied Water Systems business unit. “Exchanging the traditional sand cast bronze impeller material for the 316SS investment cast impeller will enable industry-leading hydraulic efficiencies without impacting customers’ budgets.”
Complimentary features and benefits of Xylem’s vertical turbine pumps in this size range include glass-lined cast iron bowls for strength, durability and maximized pump efficiency over the life of the pump.
The conversion will take several months and affect approximately 50 different vertical turbine impeller models. While several are already available in the 316SS material, the projected completion date for all models should be prior to the end of 2014.
After the standards change is complete, bronze impellers will remain available to customers upon request.
