The world’s first fireproof bulkhead seals are rated for gliding speeds up to 40m/s.

Featuring a dry-running gap seal, they are watertight, A-60 fireproof and electrically insulated from shafts and bulkheads.

ProfiSeal fireproof bulkhead seals are available for shaft diameters between 50mm and 500mm (larger on request) and operate in temperatures ranging from -5 to 950°C and up to two bar of pressure.

With split housings and seal rings, installation is easy. Seals are delivered with insulation material and a sheet metal cover.
