Parker Prädifa Rod Seals BD

Get a quote

The Parker PrädifaBD Ultrathan®  rod seal is a compact seal with a secondary sealing lip and an evolution of Parkerɛs Park-O-Pak® seal. The additional sealing edge results in a larger lubricant deposit in the sealing gap. This largely prevents increased wear and achieves longer service life. In addition, the need for a complex tandem arrangement may be eliminated by the second sealing lip in some cases. Hydraulic cylinders in earth-moving machines are typical applications for this seal. They may involve pressure peaks of up to 1000 bar.

  • Exceptionally high static and dynamic sealing performance.
  • Enhanced sealing performance in non-pressurized
  • Penetration of air into the system is largely
  • Robust seal profile for harshest operating conditions.
  • Extreme wear
  • Easier
  • Insensitive to extreme pressure
  • Improved lubrication due to pressure medium deposit in the dynamic contact
  • Extremely high extrusion resistance.
  • Excellent media resistance in case of suitable compound
  • Suitable compounds are available for special requirements of the chemical process industry.
  • Suitable compounds available for special requirements of the food processing
  • Dimensions according to ISO
  • Installation in closed and undercut
  • Low compression
  • Additional sizes of machined products available on short

Range of application

Mainly for sealing piston rods and plungers in heavy-duty mobile and stationary hydraulic applications.

Operating pressure                                          ≤ 500 bar

Pressure peaks                                             ≤ 1000 bar

Operating temperature                                    -35 °C to +110 °C

Sliding speed                                                    ≤ 0.5 m/s

Media                                                                  Hydraulic oils based on mineral oil

Compounds

The compound Ultrathan® P5008 is a Parker Praedifa material based on polyurethane with a hardness of approx. 93 Shore A.

NBR-O-ring with approx. 70 Shore A.

Back-up ring made of filled polyamide (W5059).

Installation

The seals should have an axial clearance (see columns H and L). To avoid damage at the sealing lips, the seals should not be pulled over sharp edges during installation. Normally these seals may be snapped into closed grooves. Where access is restricted special assembly tools may be required. Proposals for the design of such tools will be provided on request. For gap sizes see chapter “Maximum Gap Allowance”.
