Installation Instructions
The full set of cartridge seal is cleaned and passed leakage examination before sale. To avoid damage, do not disassemble and clean parts again before installation.
Step 1: The fitting allowance between seal and shaft is dl h6 0.8. Ensure leading-in edge at shaft end. Outside diameter at screw position should be 0.1-0.2mm smaller to resist screw over-tightening. Lubricate shaft with oil.
Step 2: 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
Verification: After complete installation, turn shaft by hand to check rotation. If shaft does not rotate smoothly, seal has been improperly installed.
