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.
Depending on the model, our underground tanks can be partially or fully installed in groundwater. The maximum immersion depth and the required ground cover must be observed in accordance with 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.
Flexible connections possible according to customer requirements on the tank dome up to DN 300 or on the end face up to DN 300.
Dome opening with stainless steel profile for high fitting accuracy and mounting safety.
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.
