Floor Washing System for Settled Solids and Grit

Grit deposition in storage tanks, pump stations and sewage overflow basins is an ongoing issue for many councils and water authorities. High specific gravity particles that are not able to be pumped away using existing pumps can settle and accumulate to the point where storage capacities are seriously impaired. The revolutionary Vaughan Floor Washing (VFW) System by Vaughan Co. (USA) has been designed to address this issue.

Massive new deep cone digester in Singapore to use Vaughan Rotamix

The new 17,000 m3 Digester 6 at Changi Water Reclamation Plant will be mixed using a custom Rotamix pump and nozzle mixing system.

With a diameter of 32 metres across, a sidewall height of 13.9 metres and a cone depth of 18.3 metres, Engineers working on the Digester 6 project at Changi WRP were presented with some unique challenges. One major consideration was selecting a sludge mixing system that would be capable of mixing such a large volume digester and deep cone floor. A Rotamix Process Mixing System was the answer.

Vaughan Co. release new portable engine driven chopper pump

Vaughan Company, Inc., the world’s leading chopper pump manufacturer for over 50 years have released a new heavy-duty, diesel engine driven, vacuum primed chopper pump for mobile solids handling applications. The unit is an adaption of the popular Vaughan model HE6W horizontal end suction chopper pump, designed for handling high concentrations of difficult suspended solids without clogging. With the aid of a robust venturi vacuum prime system, the unit allows for dry suction lifts up to 7.3 metres, flow rates up to 560 cubic metres per hour, and heads up to 40 metres. With the main pump wet end built to the same tried and trusted spec as regular Vaughan chopper pumps, including the heavy-duty bearing housing and “flushless” cartridge seal configuration, end users can be assured of the highest mechanical reliability in the toughest pumping applications. The pump unit has an 8″ suction flange and 6″ discharge and is powered by a top quality four cylinder, four cycle, turbocharged and water cooled John Deere 4045TF290 Interim Tier 4 diesel engine.

Big just got bigger – new 16″ chopper pump to be released

Vaughan Co., the world’s leading manufacturer of chopper pumps for over 50 years is also the producer of the world’s largest chopper pump – the Vaughan model 12W. The 12W, with its 18″ suction and 12″ discharge is capable of flow rates up to around 2200 m3/hr (611 L/s). This large pump is commonly used in municipal pump station applications and also for the mixing of high-volume anaerobic digesters and sludge tanks as part of Vaughan’s Rotamix System.

As the Vaughan chopper pump is forever proving its value as a reliable and clog-free alternative to conventional solids pumping, Vaughan Co. has recognised the need to expand on its current range and will be releasing an even larger chopper pump to cater for higher flow applications. Due to be released this year, the new Vaughan model 16W will have a 16″ discharge and will be capable of producing flows up to 3,180 m3/hr (approximately 880 L/s). This revolutionary new chopper pump will be available in multiple configurations including dry well and submersible designs, and will be ideal for high flow applications in large local authority pump stations, influent wet wells, wet weather stations and CSO basins among many others.
