Universal piston and rod hydraulic seal UPH
UPH is a symmetrical hydraulic seal that can be used for both piston and rod in the hydraulic cylinder. This type of seal has a larger cross section and can be used for a wide range of operations. It can be made of nitrile rubber or fluororubber, which provides a wider range of operating temperatures and, accordingly, a wider range of application.
Operating pressure: ≤320 bar. To prevent extrusion, when the pressure is higher than 150 bar, it is recommended to use a back-up ring at the base of the seal to ensure a larger gap during normal operation.
Operating temperature:
Standard type (NBR material): -30°C ~ +100°C
Temperature resistant type (FKM material): -10°C ~ +150°C
Reciprocating speed: ≤0.5 m/s
Media:
NBR - mineral hydraulic oils, water-glycol hydraulic oils, emulsions
FKM – mineral hydraulic oils, phosphate ester hydraulic oils
Installation:
This type of seal must have an axial clearance (please see dimensions h and H). To prevent damage to the sealing lip, avoid using sharp edges during installation.
