FRICTION-REDUCING POLYMER MATERIAL WITH DRY-RUNNING CAPABILITY AND MECHANICAL END-FACE SEAL WITH DRY-RUNNING CAPABILITY

摘要

The invention relates to a friction-reducing polymer material with dry-running capability, comprising a polymer matrix material and fillers, where the fillers comprise reinforcing particles, particles of high-hardness materials and lubricant particles. The invention further relates to a mechanical end-face seal comprising a rotating friction-reducing ring and a stationary counter-ring, where the friction-reducing ring and/or the counter-ring comprises the friction-reducing polymer material with dry-running capability. The invention further relates to the use of these polymer materials with dry-running capability for dry-running applications, more particularly as material for displacement elements in wet- and dry-running pumps.
