POLYPAC PHD SEAL

   

DESCRIPTION:

The PHD/P Seal is a high-pressure heavy-duty piston seal with excellent leakage control and superior extrusion and wear resistance The PHD/P seal is a combination of a Zurcon®polyurethane slipper seal energised by an elastomer profile ring and completed with two back-up rings (PoM). it is manufactured with a predefined interference fit, which together with the squeeze of the elastomer part ensures a good sealing effect even at low system pressure. at higher pressures the elastomer part is energised by the system pressure and consequently activates the slipper seal in the radial direction. The back-up rings prevent the slipper seal from extrusion and ensure a long service life even under harsh conditions.

 

OPERATING CONDITIONS:

Pressure: up to 35 MPa

Speed: up to 0.5 m/s

Temperature: -35 °C to +110 °C

Media: Mineral oil-based hydraulic fluids
