Mounting the Motor Unit to the Volute
Turn the latch bolts so that the motor unit runs free down to the
upper edge of the volute. Turn the latch bolts in and fasten the
screws alternately. For the torque rating see page 15.
Adjusting the Wear Ring
Lay the pump down on its side and check the clearance in
between the impeller and wear ring. The clearance should be
0.7 mm (
1
/
32
") maximum. The wear ring is placed on the bottom
side of the volute and is fastened by three screws placed
horizontally (Fig. 14).
Loosen these screws and adjust with the three vertically placed
screws. When necessary, strike carefully with a hammer or
plastic club. When the distance is adjusted, the horizontally
placed screws can be tightened. In case of T/H installation, the
wear ring can be adjusted with three vertically placed screws
from the inside of the volute. This requires, nevertheless, that the
motor unit has been dismounted from the volute.
Note! This Applies Only if Using a Channel Impeller. If
using a Vortex Impeller, do not Adjust the Wear Ring!
Testing
Connect the cables to the electric mains and start the pump. The
arrow on the cover indicates the direction of rotation. The starting
reaction will be in the opposite direction.
Note! Always Check the Lifting Handle and Screws Each
Time the Pump is Lifted Up from the Pit.
Recycling in Case of Scrapping the Pumps
The pump can be disassembled to the material level. Wear parts
made of rubber/ steel have to be treated so that the steel can be
recycled. The cable has to be treated so that the copper can be
recycled. The most positive environmental impact is achieved
when the copper is recycled. Recycling the original components
is profitable. Aluminium, copper, stainless steel, cast iron and
ductile iron should be recycled. White oil should be submitted for
burning and other materials for discarding.
