SEAL MAINTENANCE
JRZL series is designed by ‘Front Loading Seal’ that the mechanical seal system can be changed
or replaced without removing rotor case.
Check & inspect all components of seal replacement kit carefully whether there is any damage or
defect before installing. If any chipping, crack or scratch found during inspection, do not reuse
them and replace the damaged one.
Below shows the Single mechanical seal (Figure 8), Double mechanical seal (Figure 9) and
PTFE Triple lip seal (Figure 10).
If replacement for the seal ring only required, you can easily dismantle and pull it off
from rotor case just after removing rotors without dismantling for the rotor case
thanks to ‘Front loading seal design’. And put the new one and push into rotor case.
The seal ring can be easily removed from rotor by using a small
screw driver ( ̶ ) or pin as shown in Figure 11. This is common
for the Single mechanical and Double mechanical seal.
Put rotor face down on the table and pull out the seal ring from
rotor.
Put the replacing NEW seal ring on the rotor and push
downward and inserted into the rotor in Figure 12.
