Installation Preparation
- Shaft Outside Diameter tolerance: ±0.05mm
- Shaft run out: <0.1mm
- Shaft end float: <0.13mm
- No sharp edges on the shaft over the O-ring
Important Note
During installation, do not scratch or damage the O-ring. If any component is damaged, please contact us for replacement.
Installation Instructions
The complete cartridge seal set is cleaned and thoroughly tested for leakage before sale. To avoid damage, do not disassemble and clean the parts again before installation.
- The fitting allowance between seal and shaft is dl h6 0.8, with a leading-in edge at the shaft end
- The outside diameter of shaft at screw position should be 0.1-0.2mm smaller to prevent over-tightening
- Lubricate the shaft with oil before installation
- Place the cartridge seal into the pump chamber, then:
- Tighten four screw bolts of flanges, ensuring the medium leading-in hole "G" is at the top position
- Tighten four set screws to position the shaft sleeve on the shaft
- Remove four gauge plates (keep them for future installation and disassembly)
- Connect the medium lead-in pipe with hole "G" to flush away friction heat and flush the seal chamber during pump operation
Post-Installation Check
After completing installation, turn the shaft by hand to check rotation. If the shaft does not rotate smoothly, the seal has been improperly installed.
