VA Teknik - Plastic Chain Operation
The maintenance of sludge scrapers is various depending on configuration and type. The main activities when completing maintenance of these mechanical machines are the transmission chain tensioning and greasing. The previous generations of scrapers are mostly of steel chain type configurations which need a lot of greasing, often there is oil escape which increases wearing on the steel roller chain / sprockets and contaminates the water. The wearing increases maintenance costs and the oil leakage causes a reduced efficiency of the treatment, in worst case there could be a major failure.
With VA Tekniks replacement drive unit you can combine the best of two worlds.
Simplify maintenance and reduce the environmental impact. In many cases the sludge scrapers have been modernized below water line but without replacing the old drive units.
- No oil leakage
- Less spare parts
- Slim and efficient design frees space and
- increases efficiency
- Decreased power consumption
- Water lubricates the chain
- Tanks are isolated from each other
- (when doble-tanks)
- Plastic chain has longer lifetime
- Maintenance without disassembly of the drive shaft
For clarification tanks with modern sludge scraper systems but old or defect drive units.
