• Loosen the motor fastening screws (Fig. 5 Item 5) on the motor flange
and lift the motor from the pump with suitable hoisting gear. For a few
SIE pumps, the adapter ring comes loose (Fig. 5 Item 8).
• By loosening the lantern fastening screws (Fig. 5 Item 4), dismantle
the lantern unit with coupling, shaft, mechanical seal and impeller
from the pump housing.
• Loosen the impeller fastening nut (Fig. 5 Item 1.11), remove the
washer (Fig. 5 Item 1.12) and pull the impeller (Fig. 5 Item 1.13) from
the pump shaft.
• Pull the mechanical seal (Fig. 5 Item 1.21) off the shaft.
• Pull the coupling (Fig. 5 Item 1.41) with the pump shaft out of the
lantern.
• Thoroughly clean the sliding/seat surfaces of the shaft. If the shaft is
damaged, it must be exchanged.
• Remove the counter ring of the mechanical seal with the sealing collar
from the lantern flange, as well as the O-ring (Fig. 5 Item 1.14), and
clean the seal seats.
• Press in a new mechanical seal counter ring with sealing collar into the
seal seat of the lantern flange. A commercially available dishwashing
liquid can be used as a lubricant.
• Install a new O-ring in the groove of the O-ring seat of the lantern.
• Check the coupling sliding surfaces. If necessary, clean and lightly oil
them.
• Pre-install coupling shells on the pump shaft with spacer discs
inserted in between and insert the pre-mounted coupling/shaft unit
carefully into the lantern.
• Pull a new mechanical seal onto the shaft. A commercially available
dishwashing liquid can be used as a lubricant.
• Mount the impeller with washer and nut, countering on the impeller's
outer diameter while doing so. Avoid damage to the mechanical seal
due to jamming.
NOTE
Observe the specified screw tightening torque for the thread type.
• Insert the pre-installed lantern unit carefully into the pump housing
and screw together. As you do so, hold onto the rotating parts of the
coupling to avoid damage to the mechanical seal. Observe the speci-
fied screw tightening torque.
• Slightly loosen the coupling screws. Slightly open the pre-installed
coupling.
• Install the motor with suitable hoisting gear and screw the lantern/
motor (and adapter ring for SIE) connection together.
NOTE
Observe the specified screw tightening torque for the thread type.
• Push the forked spacer (Fig. 6 Item 10) between the lantern and
coupling. The forked spacer must sit there with no play.
• First, lightly tighten the coupling screws until the coupling half-shells
are in contact with the spacer discs. Afterwards, uniformly screw the
coupling together. Here, the specified distance between the lantern
and the coupling of 5 mm is automatically adjusted via the forked
spacer.
