Installation Preparation
Shaft outside diameter tolerance: ±0.05mm
Shaft run out: <0.1mm
Shaft end float: <0.13mm
No sharp edges on shaft over O-ring area
Important Note: During installation, avoid scratching or damaging the O-ring. If any damage occurs, contact us immediately for replacement.
Installation Instructions
Our cartridge seals are thoroughly cleaned and leak-tested before sale. Do not disassemble or clean parts before installation to prevent damage.
Shaft fitting allowance: dl h6 0.8 with leading edge at shaft end
Outside diameter at screw position should be 0.1-0.2mm smaller to prevent over-tightening
Lubricate shaft with oil before installation
Place cartridge seal into pump chamber and proceed as follows:
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 installation/disassembly)
Connect medium lead-in pipe with hole "G" to flush away friction heat and seal chamber during pump operation
Post-Installation Check: After complete installation, turn shaft by hand to verify smooth rotation. If shaft does not rotate smoothly, seal has been improperly installed.
