The piston rod seal type BD has two sealing lips and a thrust ring with strong extrusion resistance. Due to the action of the two sealing lips, this additional lubrication is maintained in the sealing gap. (This significantly reduces dry friction and wear, thus extending the service life of the seal.) Under certain conditions, satisfactory operation can be achieved with only two seals installed in their respective grooves, one at the front and one at the rear. The BD double seal can replace the expensive tandem device. This type of seal can be used in various situations where the physical properties of ordinary rubber or fabric-reinforced rubber cannot meet the requirements.
The main advantages are:
Excellent wear resistance.
Impact and extrusion resistant.
Small compression deformation.
Suitable for the most demanding operating conditions.
Partial lubrication.
Improved sealing at zero pressure.
Excellent protection against external air ingress.
