HP Hydraulic piston seals

HP-PSO


Description:

The PSO cuff is a double profile on the dynamic part and a surface with two small protrusions on the static part where the o-ring is fixed. The presence of an o-ring, which is the activator of the seal, provides excellent cuff operation at low and high pressure. Special double profile prevents fluid leakage in the event of hydrodynamic impact.

Reliable sealing effect.

High resistance to abrasion.

Simple groove design.


Technical specifications:

Pressure: < 250 bar at +60В°C - standard material Shore 93 A (CO).

Pressure: < 400 bar at +60В°C - alternative material Shore 98 A (DO).

Pressure: < 500 bar at +60В°C - alternative material Shore 55 D (EO).

Speed: < 0,5 m/s.

Temperature: from -35В°C to +100В°C with a peak value of +110В°C.

Operating environment: mineral oils and liquids (see Table 1 on page 1.2.4).


Material:

Name: Рїpolyurethane (PU) with hardness according to the value of the working pressure (CO or DO or EO).

The O-ring is made of NBR 70, Shor A (NO).

Material code: CN (or as an alternative to DN or EN).


Installation:

During installation, it is necessary to observe the allowable value of the roughness of the piston surface (also grinding the landing groove).

Mount the cuff for the lip of the landing groove until the piston moves lightly. The seal must always be lubricated before installation..

(For more information, see the Installation Instructions on page 1.2.14).
