Step seal
Used as a seal element for reciprocating plunger and rod.
Traditional U-packing have been challenged by high friction, reduced durability due to stick slip and oil leaks, which have been complemented and improved to address pressure, friction and wear simultaneously.
Functional advantage
-
Excellent wear resistance
-
No backsliding at high pressure
-
No stick slip due to low friction coefficient
-
Excellent high-pressure air tightness and effective in high-speed reciprocating motion
-
No adhesion.
-
Diverse dimensions teflon
-
Depending on the material of the O-ring, the range of operating temperatures is wide and adaptable to various working oils.
-
Grove arrangement is simple and easy to assemble
Feature
▶ Pressure: 450 bar maximum
▶ Temperature: -54°C ~ 200°C
▶ Speed: Up to 15m/s (a reciprocating motion)
Applied field
