- Mechanical seal R-ZF
Mechanical seal R-ZF

Temperature: ≤ +260 ºC
Pressure: ≤ 2 MPa
Speed: ≤25 m/s
Materials:
- Rotary ring: SiC/Carbon/TC;
- Stationary ring: SiC/TC;
- Bellows: VITON/Encapsulated Ring/PTFE;
- Metal parts: SUS304/SUS316/Titanium/Hastelloy-C.
The R-ZF cartridge seal is a reliable, economical and durable seal designed specifically for the paper industry.
Of the features:
- does not require external cooling;
- single seal, with the use of sealing o-rings;
- the springs are securely isolated from the product, which prevents them from clogging;
- the seal has no moving parts on the shaft, so it can be installed directly on the shaft, without an additional sleeve;
- monolithic, non-pressed rubbing surfaces, low possibility of paper drying near friction pairs;
- when starting with high torque, a special design with a uniform distribution of loads and vibration damping prevents damage to the seal.
