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 area
Important Note: During installation, avoid scratching or damaging the O-ring. If any component is damaged, contact us for replacement.
Installation Instructions
The complete cartridge seal set is cleaned and 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 there is a leading edge at the shaft end. The shaft outside diameter at screw position should be 0.1-0.2mm smaller to prevent over-tightening. Lubricate the shaft with oil.
Place the cartridge seal into the pump chamber, then:
- Tighten four screw bolts of flanges, ensuring the medium leading hole "G" is at the top position
- Tighten four set screws to position the shaft sleeve on the shaft
- Remove four gauge plates (keep them for future installation and disassembly)
- Connect the medium lead-in pipe with hole "G" to flush away friction heat and flush the seal chamber during pump operation
Final Check: After installation, turn the shaft by hand to verify smooth rotation. If the shaft does not rotate smoothly, the seal may have been improperly installed.
