PSA PISTON SEAL

 

DESCRIPTION

The PSA Piston Seal type has been conceived to work on the piston and it can be used for simple or double effect. Its has asymmetrical lips which ensure a continuous contact with the bore, even in case of high misalignments. The installation is done in semi-open groove by overlap, since the material has a high modulus of elasticity.

 

TECHNICAL DATA

PSA Piston Seal

Pressure: <400 bar at a temperature of 60°C

Speed: < 0.5 m/s

Temperature: from -35°C to +100°C, with peaks till 110°C

Fluids: mineral – based oil sand fuels

 

MATERIAL

The material used is a polyurethane with a high modulus of elasticity, low compression set and high wear resistance.

Its hardness is 93 Sh A ± 2. Compound reference: C0

 

ASSEMBLY

Remove any flash or cutting edges on the piston where the seal is housed. Ensure a lead-in chamfer in the bore to facilitate the insertion of the piston. Lubricate the packing before installation.
