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.

Whether using clean water, grey water or chemicals for cleaning, Hydra-Cell seal-less pump design eliminates seal maintenance – reducing running costs and maximising productivity.

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. Even using clean water, operating at pressures above 40 bar may cause packings and seals of piston pumps to be changed every 6 months, Hydra-Cell seal-less design eliminates this.

High temperatures, sometimes used to improve cleaning efficiency, can intensify problems for pumps with dynamic seals. Water at 90°C is 64 times more corrosive than water at
20°C. 

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 to 1mm or more) without needing fine filtration. They are also sustainably energy efficient – a big factor in their exceptionally low operating costs.

Compared with multi-stage centrifugal pumps, the pumping efficiency of the Hydra-Cell can give significant energy savings from the outset. But any seal-reliant pump, even if theoretically close to the Hydra-Cell in efficiency, will waste energy if seal wear begins and performance is allowed to fall away.
