Advantages
Thought-out in every detail
Allows easy alignment to the connecting pipes. A tank that turns it`s head for you.
Tank installation made easy! The significantly lower weight of GRAF products compared to steel or concrete cisterns makes transport and installation easier.
The tank can be partially or completely installed in groundwater. Please note the maximum immersion depths and necessary ground covers in the technical data.
The GRAF XXL tank can optionally be equipped with a second tank dome.
The telescopic dome shafts are height-adjustable and can be tilted by 5 degrees. This makes it easy to adapt to the upper edge of the terrain.
Dome opening with stainless steel profile for high fitting accuracy and mounting safety.
Flexible connections possible according to customer requirements on the tank dome up to DN 300 or on the end face up to DN 300.
Due to the constant contact with wastewater, concrete tanks are always at risk of corrosion. Depending on the degree of damage, this can result in expensive renovation of the tank. Plastic tanks are not at risk of corrosion due to their nature.
Including telescopic dome shaft truck for the installation of commercially available cast concrete covers.
