Preperation:
1. Shaft Outside Diameter is within tolerance +-0.05mm
2. Shaft run out <0.1mm
3. Shaf end float <0.13mm
4, No sharp edges on the shaft over the o ring
Note:
During the installation,don't scratch or damage the o ring.lf anything is damaged,please contactwith Us to replace a new one.
Installation in strucstions:
1. The full set of cartridge seal is cleaned and exactly passed leakage examine before sale.Inorder to avoid damage,don't disassemble and clean the parts again before fixing.
2 The fitting allowance between the seal and shaft is dl h6 0.8,and there should be leading-inedge 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
3. Place the cartridge seal into the pump chamber,then:
A: Tighter four screw bolts of flanges,ensuring the medium leading in hole"G"at the top Position
B : Tighter four set screws and position the shaft sleeve on the shaft.
C: Remove four gauge plates.Please keep them and they wil be used in future installation and
disassemble.
D: Connect the medium lead_in pipe with hole"G"in order to flush away the friction heat and
flushing the seal chamber when pump running.
Note:
ter complete the installation,turning the shaft by hand to check for the rotationi he shat could not rotate smoothily,seal had been improperly installed.
