Advantages
Thought-out in every detail
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.
Allows easy alignment to the connecting pipes. A tank that turns it`s head for you.
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.
The GRAF XXL tank can optionally be equipped with a second tank dome.
The ingress of seepage water can impair the water quality. Our tank and filter solutions are therefore sealed up to the top edge of the ground.
With GARANTIA tank systems, the connection seals are already pre-drilled and lip seals are pre-assembled. This saves time and therefore costs during installation.
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.
