Sealing Technology - Structure

For fixing the dam beams and additional protection against bouyancy, the pressing tool is inserted in the groove located in the frame once the dam beam is in place and evenly pressing all dam beams downwards with the threaded spindle.

Bonded, open-pored, acrylate-soaked PUR foam seal, compensates extreme ground unevenness and renders a ground track obsolete. With aluminium dam beams (see illustration), the ground seal is applied on a PE clamping part.

The dam beams and the end post are sealed together with a lip seal. The water pressure additionally presses this seal onto the dam beams. This seal is attached single or double-sided on the frame, depending on the application case. (single or double sealing).

Special designs of this seal are used for stainless steel dam beams that have to seal on two sides.

These seals are also available with KTW certificate for application in the drinking water sector.

The intermediate seals are located in between two dam beams each. They can be easily exchanged without tools. The seals consist of wastewater-resistant EPDM.

The intermediate seals are located in between two dam beams each. They are riveted to the dam beam with a strip. The seals consist of wastewater-resistant EPDM.

These seals are also available with KTW certificate for application in the drinking water sector. Here the seal is also used as ground seal by using a ground track.
