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 is cleaned and thoroughly leak-tested before sale. To avoid damage, do not disassemble and clean parts again before installation.
The fitting allowance between seal and shaft is dl h6 0.8. Ensure leading-edge at shaft end. The shaft outside diameter at screw position should be 01 0.2mm smaller to resist screw over-tightening. Lubricate shaft with oil.
Place cartridge seal into pump chamber, then:
- Tighten four screw bolts of flanges, ensuring medium leading in hole "G" at top position
- Tighten four set screws and position shaft sleeve on shaft
- Remove four gauge plates (keep for future installation and disassembly)
- Connect medium lead-in pipe with hole "G" to flush away friction heat and flush seal chamber during pump operation
Post-Installation Check: After complete installation, turn shaft by hand to check rotation. If shaft does not rotate smoothly, seal has been improperly installed.
