Rod pressure packing

 Main functions of rod packings :

The purpose of the packing cases is to seal (dynamic sealing) any residual gas coming from the cylinder along the piston rod.

Rod pressure packing designed to-measure

These assemblies are designed according to the nature of the gas, the discharge pressures and temperatures as well as the linear speed and stroke of the piston rod, all of which contribute to the dissipation of the heat generated.

Different designs are proposed:

• with leaked gas recovery (venting)
• with (lubricated packing case) or without lubrication
• with internal cooling
• with inert buffer gas

• with inert purge gas
• with oil recovery
