For a simple sealing point a catalog part will do. Designers come to us when the friction is too high, the space too small, the pressure too great — or when the material needs an approval.
Materials to FDA and USP Class VI, CIP- and SIP-capable, temperature-resistant to 230 °C. Designs with minimal dead volume, so that no foreign particles reach the downstream filters.
The classic case: friction has to come down, or the pressure is too high for a conventional seal. Here the lower friction power pays off directly in energy costs and service life.
Above and below the water. What counts here is pressure resistance, media resistance and the ability to seal reliably on stainless steel shafts with no post-treatment.
Applications with high reliability requirements and long service lives — often combined with special materials and small batch sizes.
Hygienic design with no cavities, no bonding agents and a smooth transition to EHEDG and DIN EN 1672-2. Plus FDA-compliant materials, metal-detectable on request. The commonest reason for an inquiry: maintenance intervals that are too short, or temperatures at the sealing point that are too high.
Where every watt of power loss counts, a seal with one third of the usual friction power is no longer a detail. The VR Low Friction sealing lip reduces it by a further 50 to 70 per cent.
