protection of the pump and motor unit.
If the motor weighs more than say two times the pump (often the case for e.g. small vertical DESMI
NSL pumps with 2-pole motor running say 2980 or 3570 rpm) it is normally better to mount the lateral
supports at the motor
’s lifting eye bolt holes (i.e. near the center of gravity for the motor).
Examples of DESMI vertical pumps with lateral supports bolted onto motor mounting flange (i.e. re-
using existing bolt holes) are shown as below:
