b. Protect the small end of the shaft (use the “Shaft protector”
(2) ).
c. Press the shaft completely down (use the “Tool for
dismantling the shaft” (7) ).
8. The internal components can now be pressed down from
the end of the bearing:
a. Reverse the pump (use the “Pump body support” (6) ).
Please remember that inner parts must be guided during this
task (use the “Tool for dismantling impellers and distributors”
(4) ).
A manual press is preferred as the mechanic can feel the
components through the inner edge of the body.
9. Remove the seal by inverting the pump (use the “Pump body
support” (6) ).
By pressing from the inside of the pump body (use the “Tool
for assembling the mechanical seal” (3) ).
NOTE 1:
If the seal is going to be re-used, protect the seal as
it leaves the body. If it falls down on a hard surface, it can be
damaged.
NOTE 2:
When requesting spare parts, please indicate the
model and serial number.
IMPORTANT:
DAMAGE to internal components may be
the result of incorrect procedures.
