9.1 Speed adjustment
If the speed needs to be adjusted, the pulleys may only be changed within the limits
specified below for the pulley dimensions and the centre distances between pump
and motor shaft. If the moment of inertia needs to be increased, a flywheel can be
fitted to the motor as an addition. In this case, select a motor with reinforced
bearings.
