The profile JPP is an radial operating sealing, that is most suitable for static applications. It consists of an U-shaped PTFE jacket and a V-shaped corrosion resistant spring. The double-mounted spring ensures a high security of the functionality. This makes the seal permanently elastic, independent of operating temperature changes, pressure, etc. The prestressing of the PTFE ring and the mechanical pretension power of the spring creates the static seal effect. The consequent pressing force gets strengthened by the system pressure, so that the total seal pressing grows by increasing working pressure. The JPP sealing replaces in many cases the conventional O-ring-back-up-ring-combination.
ADVANTAGES ARE
- resistant to most fluids and chemicals
- high seal pressing
- high and prolonged recovery
- easy installation
- broadly based application scope by a tall variety of materials
- excellent resistance to agein.
- unlimited shelf life
APPLICATION RANGE
| working pressure: | 35 Mpa (350 bar) |
| working temperature: | -150 °C up to +260 °C |
| static use |
A large application scope is given by the variety of combinations of the sealing and spring materials (for example the possible sterilization). It can be applied in apparatus engineering and plant constructions, pharmaceutical processings, cryogenics, food and beverage processings, nuclear energy technologies, aeronautics, vacuum processings as well as natural gas and mineral oil machineries. This construction is also available for static sealings at the external diameter. Please contact our consultancy service before using.
ORDER EXAMPLE
| Rod diameter: | 80 mm |
| JPP 0800 PT031 2430 D | |
| JPP | = Profile |
| 0800 | = Rod Ø x 10 |
| PT031 | = Compound |
| 2430 | = Series no., last digit: Spring code |
| D | = Cross-section |
Please pay attention:
For special applications it is recommendable to use a sealing cross section, reduced or stepped up, that differs from standard, In these cases replace the standard cross section code (e.g. „D“) by the desired one (e.g. „C“ or „E“).
For special cases of application (high temperatures, speed, specific pressure, use in water, HFA-, HFB-fluids etc.) please get in contact with our consultancy service.
