- Shaft run out: <0.1mm

During installation, avoid scratching or damaging the O-ring. If any damage occurs, please contact us for replacement.
Installation Instructions
The complete cartridge seal set is cleaned and thoroughly leak-tested before sale. To prevent damage, do not disassemble or clean components before installation.
Fitting Specifications
The fitting allowance between seal and shaft is dl h6 0.8. Ensure a leading edge at the shaft end. The shaft outside diameter at screw position should be 0.1-0.2mm smaller to prevent over-tightening. Lubricate the shaft with oil before installation.
Installation Steps
- Place the cartridge seal into the pump chamber
- Tighten the four flange screw bolts, ensuring the medium leading-in hole "G" is at the top position
- Tighten the four set screws to position the shaft sleeve on the shaft
- Remove the four gauge plates (retain for future installation and disassembly)
- Connect the medium lead-in pipe with hole "G" to flush away friction heat and maintain seal chamber cleanliness during pump operation
Post-Installation Check
After completing installation, manually rotate the shaft to verify smooth rotation. If the shaft does not rotate smoothly, the seal has been improperly installed.
