Installation Instructions
- The cartridge seal is cleaned and leak-tested before sale. Do not disassemble before installation.
- Fitting allowance between seal and shaft is dl h6 0.8. Shaft end should have leading edge. 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 to position shaft sleeve on shaft
- Remove four gauge plates (keep for future use)
- Connect medium lead-in pipe with hole "G" to flush away friction heat
Note: After installation, turn shaft by hand to check rotation. If shaft doesn't rotate smoothly, seal was improperly installed.
