We like to offer special qualities and constructions on demand.

The resistance of the materials above is depending on the concentration, denseness, grain size, temperature as well as the operating pressure of the process media.

Hose inserts are wound on a mandrel with a fabric reinforcement, hand-assembled and vulcanized.

The elasticity of the hose inserts, produced with appropriate rubber mixtures, provides the cylindric and free passage, also on the relief of the control pressure of the sleeve.

To attain optimal durabilities respectively switching cycles, the differential pressure of 2 – 2,5 bar between control and working pressure should be strictly adhered to.  The control pressure should not excess 6 respectively 8 bar.
The close cooperation with our rubber laboratory and available resistiveness lists aim to determine the most resistive rubber composite and quality for specific needs and case of operation.
Mounting Instructions for the replacement parts are available - see product selection  „technical documentation“.

Please quote the medium, concentration, temperature,
max. and min. working pressure in inquiries and orders.

We reserve the right to alter technical data.
