RDA ROTARY SEAL
The RDA rotary seal can be used as a sealing element for rotating machine parts. It is mainly
used in rotary feed units for separation of oil or other fluids at different pressures and can be subjected to
pressure on both sides. Since the seal requires only a small installation space, the external dimensions of
rotary feed units can be kept to a minimum.
