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, do not scratch or damage the O-ring. If any component is damaged, please contact us for replacement.
Installation Instructions
The complete cartridge seal is cleaned and thoroughly 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 leading-edge at shaft end. The shaft outside diameter at screw position should be 01 0.2mm smaller to resist screw over-tightening. 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 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
Post-Installation Check: After complete installation, turn shaft by hand to check rotation. If shaft does not rotate smoothly, seal has been improperly installed.
