Our ElroSeal™ technology

The ElroSeal™ sealing solutions for circumferential speeds from 20 m/s up to max. 100 m/s. This latest generation of rotary shaft seals enable reliable sealing function under limit operating conditions for industrial and automotive applications, including fuel cells. A specific solution for rotating shafts e.g. in driven tool carriers, electric motors, actuators, turbochargers or compressors.

Our ElroSeal™ SP technology

This technology, also known as Speedflon™, is a unique, patented sealing solution specifically designed for use in modern automotive supercharging systems. Using “state of the art” fluoropolymer sealing technology, combined with a pressure compensation diaphragm, this achieves exceptional sealing properties with very low friction. See download section for more details.
