Installation
Piping
Fit the gaskets between the flanges and connect the pressure and the suction pipes to
the pump.
Installation of a pump unit
Pump and motor shafts of complete pump units are adjusted perfectly in line in the
works.
1 In case of permanent arrangement place the base plate level on the foundation with
the aid of shims.
2 Carefully tighten the nuts on the foundation bolts.
3 Check the alignment of pump and motor shafts and if necessary realign, see
paragraph 3.6.4 "Alignment of the coupling".
Assembling a pump unit
If the pump and the electric motor still have to be assembled, do the following:
1 Fit both halves of the coupling to the pump shaft and the motor shaft respectively.
2 If the shaft height of the pump is not equal to the IEC size of the motor, level up the
difference by placing properly sized spacers under the pump or under the motor feet.
3 Place the pump on the base plate. Fix the pump to the base plate.
4 Place the electric motor on the base plate. Move the motor to obtain a gap of 3 mm
between both coupling halves.
5 Place copper shims under the feet of the electric motor. Fix the electric motor to the
base plate.
6 Align the coupling in accordance with the following instructions.
Alignment of the coupling
1 Place a ruler (A) on the coupling. Place or remove as many copper shims as is
necessary to bring the electric motor to the correct height so that the straight edge
touches both coupling halves over the entire length, see figure 4.

Aligning the coupling by means of a ruler and a pair of outside callipers.
2 Repeat the same check on both sides of the coupling at the height of the shaft. Move
the electric motor so that the straight edge touches both coupling halves over the
entire length.
3 Check the alignment once again using a pair of external callipers (B) at 2 diametrical
opposite points on the sides of the coupling halves, see figure 4.
4 Fit the guard.
