6.5 ALIGNMENT

Pumps supplied with motors are connected to these through a simple elastic coupling
or with a spacer.
The pumps come on the market after being aligned within the production centre; nev-
ertheless, during installation, the top part usually becomes misaligned due to anchoring
with anchor pins. Therefore, the top part needs to be adjusted by introducing metal
gauges underneath it, and aligning the pump while keeping the distances and differenc-
es within the limits shown in the Figure.

If the pump was purchased without a motor, but the intention is to connect one during
installation, you will need to correct the shift of the coupling by inserting a plate under the
feet of the motor, by adjusting the disparity according to the range shown in the Figure.
The alignment operation is achieved by removing the coupling guard, although this will
need to be refitted carefully before starting up the pump.
