Chopping Action
 

Vaughan's patented chopping action significantly reduces downtime by not only eliminating clogging problems, but also reducing downstream issues with solids. The built-in chopping design also eliminates the need for a grinder or comminutor to condition solids prior to pumping. The elimination of clogging issues means less manpower wasted unclogging pumps. All Vaughan chopper pumps are available with a written non-clog guarantee, which is your assurance of clog-free operation.

Turbo Mixer Turbo Mixer

Vaughan’s Turbo Mixer is a propeller mixer mounted vertically inside an 18” elbow. This mixer has replaced many submersible propeller mixers which have experienced motor or gearbox failure due to fluid inleakage. The Turbo can mix a pit with only one foot of liquid above the floor, something a horizontal shaft submersible mixer cannot do.

CASE STUDIES

    From Rags to Riches: Chopper Pump Gets It Done

    The North Tahoe Public Utility District (NTPUD) serves residents and vacationers in the Lake Tahoe area. Vaughan Co. provided a 50 HP, 1750-RPM model PE4P6CS-118 vertical pedestal chopper pump for the Carnelian Bay Pump Station to replace an existing pedestal pump, which was having difficulty with ragging. The Vaughan pump was intended to be driven by a Variable Frequency Drive (VFD) to provide 1150 GPM at 84' TDH at less than 1750 RPM, but because of costs the VFD was eliminated from the project.

ABOUT VAUGHAN COMPANY

Vaughan Company has a long history of innovation and quality. Jim Vaughan, the founder of Vaughan Company, invented the world's first chopper pump in 1960. The business started in the garage of Jim's gas station in Elma, Washington. Jim repaired the local dairymen's manure pumps, which experienced constant maintenance problems caused by clogging on bedding and twine. After spending many a wasted hour repairing pumps, Jim developed a unique design that effectively became the original chopper pump. Immediately, Jim realized he had invented something worthy of a patent.

In 1961, Vaughan Company purchased a 5,000 square foot building located in Montesano, Washington, This facility was previously used by the Schafer Brothers Logging Company as an engine repair facility for the railroad. Vaughan Company's current facility still incorporates the original building, but with over 35,000 square feet of additional manufacturing space.

In 1964, Vaughan Company's first patent was issued. Since then, over 40 worldwide patents have been issued or are pending. New design developments have almost exclusively centered on product improvements in efficiency and reliability in the most severe environments.

Improvements in the late 1970's included the development of a seal-and-bearing system for vertical wet well pumps to eliminate sleeve and grease packed bearings. In the 1980's, Vaughan developed the "LCC Series" of higher efficiency 3" through 6" chopper pumps. These designs were further refined with the "HP Series" and also expanded to include 8" through 12" pumps in the 1990's. The "E-Series" chopper pumps were introduced in early 2000, and included further improvements in efficiency, and back pull-out design was introduced.


Stepping into the 21st Century, Vaughan continues this pursuit of dependability using modern technology. In-house 3-dimensional computer solid modeling design allows Vaughan to create exacting fits and precision castings for all components. Computational Fluid Dynamics (CFD) analysis allows Vaughan to look closely at flow patterns and velocities within the pump, and develop premium efficiency design upgrades. Computer Numerically Controlled (CNC) automated machining creates exacting parts repetition and dependable fits with every pump.

Building a legend does take time. Dependably chopping and pumping heavy solids doesn't happen overnight. It takes years of product development and improvement, and years of proven field experience to earn the title of "Legend".
