Vaughan chopper pumps provide years of reliable digester service for Rosedale Wastewater Treatment Plant

For more than a decade, the Rosedale Wastewater Treatment Plant on Auckland's North Shore has been using Vaughan horizontal end suction chopper pumps to recirculate sludge in the plant's four anaerobic digesters. With advances in technology over the years, the originally installed Vaughan HP-Series chopper pumps have been upgraded to the new and improved Vaughan E-Series design.

The Vaughan E-Series range of chopper pumps incorporate a number of improvements including better efficiencies, back pull-out casings for ease of maintenance, and externally adjustable cutting clearances for an extended service life. Another big change is the introduction of the Vaughan "flush-less" cartridge seal. Vaughan's heavy-duty, proprietary design cartridge seal is one of the strongest and toughest mechanical seals in the industry. The unique cartridge design eliminates the stuffing box and locates the seal faces immediately behind the impeller, where cooling and seal flushing is accomplished through the action of the impeller pumpout vanes. No external water flushing is required.

These improvements, coupled with Vaughan's 50 plus years expertise in municipal sludge pumping and chopper pump design, mean that the Council and Rosedale WWTP can be assured of dependable, non-clog service for years to come.

Tasmania, Australia

Vaughan stainless steel vertical wet well chopper pumps installed for brewery process wastes

A large brewery in Tasmania needed a custom solution for a new pump station handling process wastewater containing high concentrations of vinegar and solids such as apple wastes, pips, etc. To meet the application requirements, Pump Systems offered two, 4.3m long Vaughan vertical wet well chopper pumps in all stainless steel materials, which would provide the plant with reliable clog-free operation.

The Vaughan vertical wet well line of chopper pumps are known for their reliability and long service life in some of the toughest pumping environments. With a heavy-duty oil-bath bearing and sealing system, Vaughan vertical wet well pumps can run dry without damage and do not require routine attention. An automatic oil monitoring system sounds an alarm or shuts down the pump if oil levels drop below a certain level; a direct indication of the health of the mechanical seal. While the unique machined motor stool eliminates the risk of coupling misalignment and bearing failure, even during the heaviest of chopping applications.

South Island, New Zealand

Boerger rotary lobe positive displacement pump supplied for fish oil transfer on board deep sea trawler

A custom-built Boerger model AL 50 rotary lobe pump was supplied by Pump Systems to a major New Zealand fishing company for transferring fish oil on board a deep sea trawler. Made in Germany and ideal for gentle, pulsation-free conveying of viscous, solids-laden and shear-sensitive fluids, Boerger rotary lobe positive displacement pumps are extremely versatile and are available in a wide range of special configurations.

Due to space constraints on the vessel, this particular pump was designed for vertical installation and was supplied with a 2.2kW, 4-pole speed geared motor operating at 650 rpm. As standard, Boerger pumps are fitted with silicon carbide faced mechanical seals with separate lubrication and carbon steel shafts (not in contact with the pumped media). An intermediate chamber with quench fluid protects the mechanical seals and rotor/shaft connection while also protecting the gears against penetration of the pumped media.
