1 Place a ruler (A) on the coupling. Remove or add as many 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.
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 To be certain the check is also undertaken using external callipers (B) at 2 corresponding points
on the sides of the coupling halves, see figure.
4 Repeat this check at operating temperature and spend time achieving minimum alignment
deviation.
5 Fit the protecting guard. See the figure below and the corresponding table for the maximum
allowed tolerances for aligning the coupling halves.

Belt drive
Belt drives also increase the loading on the shaft end and the bearings. Therefore, certain limitations
must be imposed on the maximum load of the shaft, viscosity, pumping pressure and speed.
See section 3.18.3.2 Radial load on shaft end.
3.18.7.7 Guarding of moving parts
Before commissioning the pump, place a protective guard over the coupling or belt drive. This guard
must comply with the EN 953 design and construction standard.
For pumps operating at temperatures above 100°C, ensure that bearing bracket and bearings are
cooled sufficiently by the surrounding air.
3.18.7.8 Check temperature censor on can
In case the pump is provided with a PT100 element,
the electrical connections must be made by an
approved electrician.
