PARKER DP PNEUMATIC SEAL

    Pneumatic Seal DP

    The double-acting profile DP is a complete pneumatic piston with a double cup seal and a vulcanized metal disc support. It performs three functions:
    Sealing, guiding and cushioning.

    • Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
    • Cushioning buffers on the piston´s front faces with integrated ventilation ducts provide for mechanical cushioning of the cylinders.
    • Multi-functional element: seal, guiding and cushioning element.
    • Immediate response (full pressure load) thanks to incorporated venting channels.
    • Good wear resistance.
    • Ideal corrosion protection thanks to complete elastomer covering.
    • Smooth running due to optimum adjustment of the functional lips.
    • Easy attachment to the piston rod without additional sealing elements.
    • Easy installation due to integrated static sealing function.
    • Excellent media resistance in case of suitable compound selection.
    • Low assembly height of the complete piston enables short cylinder designs.
    • Versatile complete piston for nearly all cylinder designs.

    Range of application
    Complete piston with end cushioning for double-acting pneumatic cylinders, provided that no excessive lateral guidance loads will occur (long strokes and buckling).
    Operating pressure≤ 12 bar
    Operating temperature-30 °C to +80 °C
    Sliding speed≤ 1 m/s
    MediaCompressed air, both lubricated and oil free (after greasing for fitting)

    Installation
    The profile DP pneumatic complete piston should be fixed to the piston rod with a locknut to avoid loosening. For use with dry and oil-free air, the piston and cylinder tube must be prelubricated with a suitable long-life lubricant.
