High pressure, high speed, low friction piston rod seals Structure and characteristics
Update:2017-02-11
With the development of civil society, energy, mining, metallurgy, railways, highways and construction industries, often encounter high-pressure, high-speed, low-friction piston rod with sealing structure and sealing ring. They are often referred to as "combined seal".
Working condition
Type Material Temperature Speed Pressure
Step Seal Filled PTFE -50°～+225° ≤15 ≤70
Glyd Ring Filled PTFE -50°～+225° ≤15 ≤70
Piston rod seals Filled PTFE -50°～+225° ≤15 ≤70
The above working parameter is offered by DSH Seals, please refer to the actual working condition.
DSH Seals offer high pressure piston rod seals, high speed piston rod seals, low friction piston rod seals, and other harsh working condition piston rod seals, contact us freely.

The above piston rod seals structure.
1 Combined seals, produced by the o-ring prestressed, plays a role of compensation in the initial state and working.
2 Friction force is small, due to the filling material such as graphite, bronze, carbon fiber, glass fiber and so on, reduce the friction resistance, improve the wear resistance, the friction coefficient f < 0. 04.
3 Allow high linear velocity, v 15 m/s or less.
4 High temperature resistance.
