Installation Preparation Requirements
- 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 Installation Notes
Avoid scratching or damaging the O-ring during installation. If any damage occurs, contact us immediately for replacement. Our cartridge seals are thoroughly cleaned and leak-tested before sale - do not disassemble before installation.
Installation Instructions
- Ensure shaft fitting allowance is dl h6 0.8 with leading edge at shaft end
- Lubricate shaft with appropriate oil
- Place cartridge seal into pump chamber
- Tighten four flange screw bolts, ensuring medium leading hole "G" is at top position
- Tighten four set screws to position shaft sleeve on shaft
- Remove four gauge plates (retain for future use)
- Connect medium lead-in pipe to hole "G" for friction heat dissipation and seal chamber flushing
Final Check: After installation, manually rotate shaft to verify smooth operation. Any resistance indicates improper installation.
