In many applications, the sealing gap is too large for a static sealing element or the seal must be able to be activated (adjacent) or deactivated when opening or closing door or sliding elements.
Activatable seals also serve to generate pressure, for example to press 2 objects together.

 

More than one seal:

Lifting or holding functions also belong to the tasks of our inflatable seals.

The functional principle is identical to our inflatable seals.

Our innovation: Our production data, as well as your specific data such as

  • your article number 

  • Material and hardness

  • Installation date of the seal

  • Valve data,

can be conveniently read from a safe distance while your system is running. Without interrupting production.

Inflatable seals - execution

Inflatable seals

ring cord seal

Depending on the installation situation, seals will be axial, radial-inner or radial-outner sealing. In order for the profile to function optimally, it is important that minimum radii are taken into account. These minimum radii are directly related to the selected profile. Endless seals have a vulcanization point. These joints have almost the same chemical and thermal properties as the profile.

Seals with end plugs

Sealings with end plugs are not endless, i.e. the gaskets each have end pieces that are fitted with an elastomer plug. It is possible to produce an end piece in a retracted or expanded state.

Valve locking and positioning

Valves are installed in the bottom of the profile for expansion seals. In the case of expansion seals, it is possible to install the valve in the bottom of the profile or on the side. The valve is secured mechanically or by the additional attachment of a cone to stabilize the valve.

Operating mechanisms

Low pressure roller

With this standard, the sealing surface is rolled out.

Benefits:

  • Sealing of larger sealing gaps at lower pressures  

  • for lifting small loads

Basic roller

Due to this principle, the sealing surface remains undeformed and offers the following advantages:

  • Dead space-free sealing surface -> germ formation is prevented  

  • Material stretching when rolled out is avoided

  • large sealing gaps (up to 12 mm) can be managed

High pressure expander

  • Overcoming small sealing gaps       

  • Material expansion in the activated state                

  • higher contact pressures than roll-out seals            

  • this type of extrusion is suitable  himself  especially to hold,   

     Clamping or lifting of components   

  • Sealing of higher ambient pressures,  

     due to strong wall thicknesses
