GER PSN is a two piece double acting piston seal which consists of one special mixture PTFE profile ring and an o-ring as energizing element.The GER PSN type piston seal has been designed for both pneumatic and hydraulic applications.Due to its elasticity can also be assembled on monoblock piston type. Its main characteristic is an exceptional smoothness that allows to use this seal even with low lubricity fluids such as air and water. many tests have given positive results as regards the absence of extrusion of the profile even with the passage of the seal on the drainage holes of the system.

PRODUCT ADVANTAGES

• Low friction , free of stick-slip
• Simple groove design and low axial housing heights .
• Long service life
• High sliding speed
• Wide range of temperature and chemicals depending on the o-ring material
• Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature
• Wide range of dimensions                                                                            

APPLICATION:

Injection moulding machines , fork-lift trucks , loading platforms , cranes , agricultural machinery and valves for hydraulic and pneumatic systems. 

ASSEMBLING
Installation is in elastic way in anular housing. Remove the burrs mechanical and lubricate the seal with grease. The bore must present a lead-in chamfer

MATERIAL

The material of the sealing element is a polymer with high elasticity, while as for the energizing element using an O-ring in NBR 75 Shore A. Alternative material should be use for sealing PTFE filled carbon-graphite, while for the element energizing O-ring materials such as HNBR or FKM.
