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.


• The HVAC industry’s first wireless pump monitoring system that allows remote monitoring via the Internet 24/7 from any location in the world as a standard option.


• First built-in generator to power the pump’s sensors and data monitor.


• 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
