7 Complete pump overhaul / Dismantling
Dismantle the pump as described in the sections 2-6.
Note!
Oil drainage, mechanical seal and wear plate disman-
tling can wait until cooling jacket is removed.
7.1 Electrical supply leads
Disconnect all electrical leads from the terminal board /
contactor in the pump. Then start to remove power and
control cables from the pump. (Figure 13)
J 205: The power and control cable are incorporated
in the top cover and will be removed when cables are
disconnected from the terminal board /contactor. Re-
move cable clamps prior to unscrewing cable gland
from cover. Pull out cables.
J 405: Remove cable clamps prior to unscrewing cable
gland from upper motor part. Unscrew cable gland and
pull the cable out together with the cable gland.
J 604: Remove cable clamps prior to unscrewing nuts
that hold the cable gland and pull the cable together
with the cable gland out.
Check the condition of the cable, cable seals and cable
glands when cover is removed. When a cable seal is
removed always replace it with a new.
7.2 Discharge connection
Unscrew the nuts that hold the discharge elbow and
remove it. (J 604 has a clamping ring holding the dis-
charge connection.) (Figure 13)
7.3 Cooling jacket
Make sure all inspection plugs are removed from the
cooling jacket prior to dismantling cooling jacket.
J 205: Lift the pump up in the handle into a vertical
position with a lifting device and secure it. Put the pump
standing on the outer longer stud bolts. Place a dis-
tance piece under the diffuser stud bolts (preferably a
wooden frame at a diameter of the diffuser stud bolts).
Loosen the stud bolts holding the cooling jacket and lift
off the cooling jacket from the motor housing. (Figure
14)
J 405:
Remove the handle from the pump when it is
lying down. Thread on an eye bolts on to the shaft end.
Lift the pump and place it in an upside down position on
the connection chamber secured by the lifting device.
Use a dead blow (plastic hammer) to force the cooling
jacket down until it releases from the motor housing. Lift
out the complete motor housing and put it lying down.
(Figure 15)
J 604: Unscrew the lifting eye on top of the pump and
remove them. Fit an eye-bolt at the end of the shaft and
use a chain to lift and raise the pump into an upside
down position standing on the connection chamber.
Unscrew nuts to release the oil housing from the outer
jacket. Lift up and withdraw the motor housing and oil
housing together out of the cooling jacket.(Figure 15)
