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 area

Important Note: During installation, avoid scratching or damaging the O-ring. If any component is damaged, contact us for replacement.

Installation Instructions

The complete cartridge seal set is cleaned and leak-tested before sale. To avoid damage, do not disassemble and clean parts again before installation.

The fitting allowance between seal and shaft is dl h6 0.8. Ensure there is a leading edge at the shaft end. The shaft outside diameter at screw position should be 0.1-0.2mm smaller to prevent over-tightening. Lubricate the shaft with oil.

Place the cartridge seal into the pump chamber, then:

Tighten four screw bolts of flanges, ensuring the medium leading hole "G" is at the top position
Tighten four set screws to position the shaft sleeve on the shaft
Remove four gauge plates (keep them for future installation and disassembly)
Connect the medium lead-in pipe with hole "G" to flush away friction heat and flush the seal chamber during pump operation

Final Check: After installation, turn the shaft by hand to verify smooth rotation. If the shaft does not rotate smoothly, the seal may have been improperly installed.

We are committed to cooperating with clients to supply high-quality products and services. We believe establishing long-term cooperative relationships is key to mutual success.
