Vehicle Washing

November 29th, 2009

Vehicle Washing

The high costs of using and disposing of water oblige vehicle wash systems to rely increasingly on recycled water.  Even after filtration this will contain chemicals in solution and is likely to carry particles of grit and other contaminants.  Pumping it is potentially damaging for pumps with seals.

Operating at pressures above 40 bar, even using clean water, may cause packings and seals of piston pumps to be changed every 6 months. Hydra-Cell’s seal-less design means that this maintenance is not needed.

Why Hydra-Cell?
Hydra-Cell pumps are seal-less. No seals, no seal wear – No leaks. No loss of performance. No frequent repairs. Less downtime. Long-term reliability, with minimal routine maintenance and low repair costs.

Hydra-Cell pumps can handle solids up to 1mm, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Most pumps in the Hydra-Cell range can operate at any pressure from <1 bar up to at least 70 bar. Some models up to 170 bar.

Flow is steady, with little pulsation.

Hydra-Cell pumps can run dry without damage. Innovative Kel-Cell technology protects diaphragms even in abnormal system conditions.

Sealed pumps may be vulnerable in a low pressure system.  In cleaning systems working at higher pressures (e.g. above about 20 bar) the risks of rapid seal wear, loss of performance and premature pump failure increase.

Hydra-Cell seal-less pumps are used in vehicle cleaning systems not only for their high pressure capability, but because of their simple build, low maintenance and reliability.  They tolerate chemicals and abrasive particles (up to1mm or more) without needing fine filtration.  They are also energy efficient – a big factor in their exceptionally low operating costs.

Most pumps in the Hydra-Cell range can operate at any pressure from <1 bar up to at least 70 bar. Some models up to 170 bar.

Energy savings. Compact and highly efficient (80-85%), a Hydra-Cell pump can be fitted with a smaller motor than would be required by much bigger pumps for equivalent flows and pressures

Vaughan Chopper Pump

Vaughan Chopper Pump

Vaughan’s chopper pump is the heart of the Rotamix System. Vaughan’s proven technology over the past 40 years provides long term low maintenance, and the highest reliability of any chopper pump. Continuously chopped solids not only eliminate nozzle clogging, but enhance sludge quality. Digester efficiency is increased by further reducing solids size and increasing surface contact.
Vaughan’s unique features necessary to provide this reliability include:

  • Patented chopping design eliminates nozzle clogging
  • Wear parts heat treated to 60+ Rockwell C Hardness extends pump life
  • Oversized shafting and bearings extends pump life
  • Heavy duty mechanical seal (optional “flushness” seal design) assures leak-free operation
  • Back pull-out design allows adjustment of all cutting clearances without disconnecting suction or discharge piping

Other configurations available include vertical dry pit, submersible, self-priming, vertical wet well, and recirculating pumps. All Vaughan pumps include a written Performance Guarantee, your assurance of clog free pump operation.

Rotamix® Nozzle Assemblies

August 17th, 2009

Rotamix SingleThe Rotamix® system nozzle assemblies (patent pending) are offered in single, double and triple nozzle configurations. Each assembly is designed for permanent installation without further adjustment or maintenance.

  • Nozzles are manufactured from 1-inch thick ductile cast iron hardened to 450 Brinell Hardness, assuring long life without maintenance
  • The remaining ductile iron assembly piping components are concrete lined for resistance to both corrosion and abrasion resistance
  • Each assembly includes a 10-year full warranty
