PZP
The profile PZP is a elastomer cylinder seal that is designed for both-way impingable pistons in the pneumatics. On the strength of two very small seal edges and the lubrication reservoir fixed between, it is characterized by an extreme smooth run.
ADVANTAGES ARE
- low static and dynamic friction on the strength of small width of section
- very smooth-running because of lubrication reservoir
- long working life after thorough initial lubrication
- even usable with dry and oil-free air
- high seal effect at smallest space requirement
- simple mounting by pulling over even on closed fitting area
APPLICATION RANGE | |
working pressure: | ≤ 1,2 MPa (12 bar) |
working temperature: | - 20 °C to + 100 °C < FKM to + 200 °C |
surface speed: | ≤ 1,0 m/s |
media: | Pressure air, lubricated as well as oil-free (after initial lubrication) |
For using this seals, we recommend guiding elements (e.g. profile F2S). Chiefly used for the sealing of pistons in pneumatic cylinders and valves.
MATERIAL
Standard compound is a NBR-based elastomer with a hardness of approx. 71 Shore A. Special compounds are available for high resp. low temperature applications.
MOUNTING INSTRUCTIONS
The profile PZP is mountable problem-free on one-piece pistons by pulling over. The seal should not be pulled over sharp edges during installation. Therefore, these edges at the piston and at the cylinder liner should be broken. To ensure working at dry run and a long working life, a closed lubrication film should be brought on in the cylinder liner before the mounting of the piston. When using the guiding band F2S, the outside diameter of the piston is to achieve exactly so that the gap sizes listed at the profile F2S arise.
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.
