EWS.HPC-Line

High pressure: up to 70 bar

Nmax: up to 12,000 1/min

Dry running: Unrestricted

The time when you had to decide between using high speed in conjunction with low coolant pressure or high pressure at low speed is over. The newly developed EWS.HPC-Line sealing technology now represents a further quantum leap. The seal set, which is based on technical ceramics, is capable of covering 70 bar at up to 12,000 1/min. Added to this is unrestricted dry-running capability.

The running-in process in particular meant the technical knockout for many sealing systems after only a short time, because the previous seals burned out after only seconds or they hardened, which then led to failure within a very short time. The technical ceramic used in the HPC-Line has excellent dry-running properties, which was a key criterion in the developers' specifications.

Even in terms of heat generation, there is something positive to report, because the high-precision face seal causes far less heat than was the case with lip seals due to the optimized friction factor µ. In addition, the frictional force FR= µ x FN was reduced to a minimum through geometry optimization and intelligent load balancing at the sealing elements.
