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 area
Important Note: During installation, avoid scratching or damaging the O-ring. If any component is damaged, please contact us for replacement.
Installation Instructions
Our cartridge seals are thoroughly cleaned and leak-tested before sale. To prevent damage, do not disassemble or clean components before installation.
Fitting Specifications:
- Seal-to-shaft fitting allowance: dl h6 0.8
- Leading edge required at shaft end
- Screw position shaft diameter: 01 0.2mm smaller to prevent over-tightening
- Lubricate shaft with appropriate oil
Installation Steps:
- Place cartridge seal into pump chamber
- Tighten four flange screw bolts, ensuring medium leading-in 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 maintain seal chamber during pump operation
Post-Installation Check: After installation, manually rotate the shaft to verify smooth rotation. If rotation is not smooth, the seal has been improperly installed.
