CHOPPER PUMPS - Pump Systems

1 The Solids Handling SpecialistsCHOPPER PUMPSP R O D U C T C A T A L O GWith almost 25,000 units in service, the Vaughan CHOPPER Pump has not only proven its value in problem solving, but also established itself as the reliable alternative to conventional pumping. Over the years, product reliability has also allowed Vaughan to GUARANTEE the performance of all CHOPPER PUMPS . This guarantee is your assurance of clog-free solids-handling performance, not just another materials-and-workmanship warranty. Vaughan celebrates its 50th year and beyond by introducing larger sizes, new configurations, and advances in efficiency, maintainability and performance with the E series flushless seal design.

2 We invite you to study the features in this catalog and compare. Then, we believe you will agree that the Vaughan CHOPPER Pump is A Cut Above the Rest .For over 50 years, Vaughan has been the market leader in manufacturing CHOPPER PUMPS , solving today s toughest solids-pumping problems. This family driven tradition all started with Jim Vaughan s dream of a better, more reliable means of pumping manure. Today s third and fourth generation of the Vaughan family continue the tradition of quality, dependability and GuaranteedOver 50 Years of TraditionThe late founder, Jim Vaughan (standing), and his son Larry (sitting)

4 Cuts stringy materials that tend to wrap at the pump are chopped by the cupped and sharpened impeller blades turning across the cutter bar, creating a smooth slicing effect. The conditioned slurry is easily pumped through the pump and piping system without solids trapped in the mechanical seal area are shredded and removed by the impeller vanes turning against the upper cutter, providing reliable service over the long s unique cartridge style mechanical seal handles the toughest slurries, outperforming standard single-spring seals by reducing problems associated with wrapping or cutters above and below the impeller create a more efficient cutting system which binds less on high-fiber slurry.

5 Reducing motor overloads and nuisance tripping. These extra, hardened steel, patented cutters are one of the critical differences between Vaughan and the CHOPPER PUMPS are not to be confused with other types or brands of CHOPPER PUMPS , cutter PUMPS , grinder PUMPS or comminutors. Some of the unique patented features specific to Vaughan CHOPPER PUMPS which make the product so dependable are:Vaughan CHOPPER PUMPS incorporate increases in efficiency, with improved reliability handling tough stringy solids.

7 This type of mixing allows digesters to regain their design capacity, extends the time between cleanouts and generates more methane gas. The Vaughan Scumbuster operating with the Vaughan CHOPPER pump on digester recirculation has proven successful not only to eliminate heat exchanger clogging, but also to replace other failed digester mixing Wet Welll Oil lubricated bearings eliminate water or grease lubricated sleeve bearingsl Capable of running dryOIL-FILLED BEARING HOUSING Increases bearing lifeSEAL-AND-BEARING SUB-ASSEMBLY Reduces maintenance timeDUCTILE IRON CASING AND BEARING HOUSING Increases durabilityDOUBLE-ROW THRUST BEARINGS Absorb all impeller loadsVAUGHAN S CARTRIDGE STYLE SILICON CARBIDE MECHANICAL SEAL Protects bearings and lasts longerPUMP-OUT VANES AND UPPER CUTTER Keeps pumpage away from sealCAST ALLOY STEEL IMPELLER, CUTTER BAR.
