General
The profile ZER is a double-acting rod seal and is mainly used in valves and spindles. There is a one-piece elastomer body in the centre which is reinforced on both sides of the inner diameter with polyacetate-based support rings to prevent gap extrusion. This profile can also be used in water hydraulics. Set code SN250 = support ring slotted, set code SN254 = endless support ring
Medium
Can be used in mineral oil, HFA and HFB fluids as well as water
Material
Standard material:
- Sealing ring: FKM compound
- Back-up rings: Polyacetate base (POM)
Advantages
- wide media resistance
- insensitive to pressure peaks
- good availability of intermediate sizes
Installation instructions
To ensure proper function, the rod seal set ZER must have axial play in its groove. To prevent the seal from being damaged, it must not be pulled over sharp edges. The seal set can be installed in closed grooves by means of a snap-on assembly. For special applications (high temperature, speed, specific pressure load or use in HFA and HFB fluids etc.) please contact our application engineering department.
Other
For use in HFA and HFB fluids, please note the temperature limits of -5°C and +60°C.
