Installation Preparation
- Shaft Outside Diameter is within 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, do not scratch or damage the O-ring. If anything is damaged, please contact us to replace with a new one.
Installation Instructions
- The full set of cartridge seal is cleaned and exactly passed leakage examination before sale. To avoid damage, do not disassemble and clean the parts again before fixing.
- The fitting allowance between the seal and shaft is dl h6 0.8, and there should be leading-in edge at the end of shaft. The outside diameter of shaft at the position of screw should be 01 0.2mm smaller, resisting the screw over-tighten. Lubricate the shaft with oil.
- Place the cartridge seal into the pump chamber, then:
- Tighten four screw bolts of flanges, ensuring the medium leading in hole "G" at the top position
- Tighten four set screws and position the shaft sleeve on the shaft
- Remove four gauge plates. Please keep them as they will be used in future installation and disassembly
- Connect the medium lead-in pipe with hole "G" to flush away the friction heat and flush the seal chamber when pump is running
Note: After completing the installation, turn the shaft by hand to check for rotation. If the shaft does not rotate smoothly, the seal has been improperly installed.
