DUOPAC rubber fabric reinforced compact seals
Type DPS and DPC

Description

The COMPACT SEAL POLYPAC – DUOPAC DPS-DPC types are
double acting piston seals with integrated guide rings.
DUOPAC has been designed to optimize the advantages
of the materials selection:

  • Fabric reinforcement with high mechanical strength, optimum thermal stability and lubricating properties is incorporated in the sealing element all over the dynamic contact area. For the DUOPAC DPC the reinforcement is extended on both sides to improve the extrusion resistance
  • Nitrile based elastomer with optimum elasticity and low compression set provides the initial radial pre-load
  • Acetal resin with improved form stability gives the Guide/backup rings high distortion and extrusion resistance

Type DPS

The DPS profile has been designed for its installation in closed grooves. The radial dimension of the profile has been reduced to the minimum to allow the necessary deformation during installation in closed grooves. Consequently its use must be limited to pressures up to 35 MPa.

Type DPC

The DPC profile is much more robust and can therefore be used for pressure level up to 70 MPa. An open groove is necessary.

Advantages

– DPS can be installed into closed grooves but its usemust consequently be limited to medium duty applications
– DPC are usually installed in open grooves inHeavy Duty applications (pressure peak up to 80MPa)
– Improved abrasion resistance
– Excellent sealing effect in combination with good dynamic and static friction behavior

Application Examples

  • The Compact seals are the recommended Sealing element
    for double acting Pistons of hydraulic components
    in following applications:
  • Mining cylinders
  • Presses
  • Steel mills equipment
  • Water hydraulic cylinders

Technical Data

Operating conditions:
For an optimumperformance of theDUOPAC, the recommended tolerances and surface finish must be applied.

Pressure: Up to 35MPa DPS type
Up to 70MPa DPC type

Speed: Up to 0.5 m/s

Temperature: -30C to +130C

Media: Mineral oil based hydraulic fluids,
water/oil and water/glycol emulsions.

Important Note:

The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Temperature range also dependent on medium.
