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.
We would like to sincerely cooperate with clients to supply high quality products and service. We believe in establishing a long-term cooperative relationship is the key to success.
