BASE ALIGNMENT
Pump / base assemblies are aligned in Q-Pumps factory prior to shipment. However assembles
must be checked prior operation to avoid any misalignment. Misalignment may cause unneces-
sary wear and shorten the life of the pump. You can notice misalignment with excess noise and
vibrations. To check and align the pump to its drive first remove the coupling guard.
COUPLING GUARD
Proceed to verify the angular alignment by measuring the space between the couplings in both
vertical and horizontal direction. The measured space has to be equal at both sides of the coupling
use shims in the pump base or motor base if needed. Proceed to align the pump and drive para-
llel to the axis of rotation. Use a straight edge in both top and side of the couplings to guarantee
parallelism.
