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
Note: During installation, avoid scratching or damaging the O-ring. If any damage occurs, contact us for replacement.
Installation Instructions
The complete cartridge seal set is cleaned and leak-tested before sale. Do not disassemble and clean parts again before installation to avoid damage.
  • Shaft fitting allowance: dl h6 0.8 with leading edge at shaft end
  • Shaft 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, then:
  1. Tighten four flange screw bolts, ensuring medium leading hole "G" is at top position
  2. Tighten four set screws to position shaft sleeve on shaft
  3. Remove four gauge plates (keep for future installation/disassembly)
  4. Connect medium lead-in pipe with hole "G" to flush away friction heat and seal chamber during pump operation
Note: After installation, turn shaft by hand to check rotation. If shaft doesn't rotate smoothly, seal was improperly installed.
