Features

• Symmetrical, single acting piston/rod seal, combined with pressure ring and support ring.
• By adjusting the number of packings friction and leakage characteristics can be influenced.
• Excellent static and dynamic sealing performance.
• Excellent performance in high pressure conditions.
• Useable for short and long stroke lengths.
• High wear resistance.

Application

Reciprocating pistons/rods in hydraulic cylinders, plungers etc.

Used in heavy duty applications (presses) with return stroke by equipment weight. Max. pressure 500 bar, max. speed 0.5 m/s.

Installation

Installation normally in open housings.

At closed housings the parts need to be split. In this case the seal must be done  slightly larger (approx. 1% in diameter)
