Technical Consultation and Service:

We will help you find the best solution for your seal problem. Send us your drawing/sketch, working conditions (dimensions, shaft/housing material, operating speed, medium, pressure, life expectancy etc.). All recommendations and data are based on the experience gained over decades of using those SEALS. Unknown factors and special conditions may restrict the generally valid promises. In critical cases we suggest tests with samples.
