PTFE seals 10t John Crane Mechanical Seal for minielectric water
pump
YUEMI WB2 is identical to john crane 10tmechanica sea
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.
