It sounds to me like someone on the agitator side didn't do their homework on the fluid properties - or didn't choose the correct diameter impeller for the agitator. On the motor side, if the machine is running slightly fast (i.e. lower-than-expected cage resistance in the rotor, for example) the power draw - and, consequently, the current draw ...

Use this MS Excel spreadsheet to calculation the power requirements and mixing intensity for a defined mixing application.
Propeller turbine mixer design calculator solving for Reynolds number given impeller diameter, fluid dynamic viscosity, revolution per second and liquid mass density
deﬁned as the ratio of the agitator power in an aerated ves-sel (P g or "gassed" agitator power) to the agitator power in an unaerated vessel (P u or "ungassed" agitator power). Most of the time, the upper impellers are up-pumping. This arrangement is more mechanically stable than down-pumping impellers. In more tangible terms, the ...
A 1-hp, 6-pole motor will develop 50% more torque than a 1-hp, 4-pole motor If the manufacturer of the agitator is provided with the density of the material beforehand they should determine what torque is required and supply a motor to suit.
