Revolutionary New VSX Pumps Feature Several “Industry Firsts”

Morton Grove, Il, September 29, 2005
A new series of split-case pumps with several features never before offered in the HVAC industry has been introduced by Bell & Gossett®.

Aptly named the VSX Series (vertical split-case excellence), the new pumps are designed to provide unparalleled performance and reliability over a wide range of applications. Based on extensive research and feedback from more than three hundred (300) end users around the world, Bell & Gossett has created a double-suction, split-case, base-mounted, centrifugal pump offering these unique “industry first” features:

• Multiple suction and discharge flange configurations that maximize piping possibilities can reduce the overall equipment footprints by up to 40%. The VSX connection options include the VSC model (Top Suction -Top Discharge flanges), VSCS model (Side Suction -Top Discharge flanges) and the VSH (Side Suction, Side-Discharge flanges).
• The hydraulic matching of the pump impeller and casing was achieved by utilizing Computational Fluid Dynamics (CFD). The result is a product offering superior performance in chillers, cooling towers, distributive pumping and a wide range of additional applications.
• The CFD process also allows any one of the three VSX models (VSH, VSC & VSCS) to provide the identical level of hydraulic performance – no matter what orientation of the pump flanges are selected.
• A groutless base plate that significantly reduces labor and material costs during installation.
• Unique “Plug-n-Play” capability that allows simple field modifications for mechanical seals, external seal flushing and wireless monitoring.

Other features of the pump include:

• Flows from 500 – 15,000 GPM
• Heads from 30 – 425 feet
• Working Pressures of 175 and 300 psig
• ANSI Flange Ratings of 125 and 250 lb.
• Temperature from 0 to 300 Degrees Fahrenheit
• Internally Self-Flushing Mechanical Seals
• ANSI / OSHA coupling guard
• Alignment-friendly, variable speed capable coupling
• One-piece unitized mechanical seal to simplify servicing
• Maintenance-free bearings

“Based on our comprehensive Voice of the Customer (VOC) program that consisted of interviewing hundreds of our customers, we have created a pump that features the ultimate in high efficiency hydraulic design, reliability, and installation versatility”, said Steve Schmitz, Sr. Product Line Manger for pumps at Bell & Gossett. “The industry experts – our customers, told us what they wanted and we’ve delivered a unique series of pumps designed to their specifications.” The new VSX pumps will be available to the HVAC industry in February and will feature 36 sizes and models.

Bell & Gossett, a unit of ITT Industries, is a leading manufacturer of centrifugal pumps, hydronic specialties, heat exchangers, condensate handling equipment, and packaged systems for variable and constant speed pumping, heat transfer and pressure boosting.
