The field of application ranges from high vacuum to pressures of 30bar, from slow turning shafts to 150m/s sliding speed, at operating temperatures from 190°C to 600°C for media from plain air to highly toxic and/or abrasive gases.
The STASSKOL DynamicSeal SDW20 consists of the housing and 3 to 7 sealing rings according to the variation. The most current variation is the SDW20-kv-S, the short design with reduced outside diameter and a connection for buffer gas.
Various PTFE compounds and special artifical carbon grades are available for the sealing rings. These materials are applied in high-temperature aplications up to 600°C. The available sealing materials have been designed to run dry and do not require any lubrication.
