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, avoid scratching or damaging the O-ring. If any component is damaged, contact us immediately for replacement.
Installation Instructions
The complete cartridge seal is cleaned and leak-tested before sale. Do not disassemble or clean components before installation to prevent damage.
Step 1: The fitting allowance between seal and shaft is dl h6 0.8. Ensure leading-edge at shaft end. Shaft diameter at screw position should be 0.1-0.2mm smaller to prevent over-tightening. Lubricate shaft with oil.
Step 2: Place cartridge seal into pump chamber, then:
- A: Tighten four flange screw bolts, ensuring medium leading hole "G" at top position
- B: Tighten four set screws to position shaft sleeve on shaft
- C: Remove four gauge plates (retain for future installation/disassembly)
- D: Connect medium lead-in pipe with hole "G" to flush away friction heat and seal chamber during pump operation
Final Check: After installation, turn shaft by hand to verify smooth rotation. If shaft doesn't rotate smoothly, seal was improperly installed.
