Torque controlled pump protection with mechanical loss compensation

A centrifugal pump, centrifugal blower, centrifugal mixer or centrifugal compressor pump having a controller for controlling the operation of the pump characterized in that

• the controller either adjusts the operation of the pump, or issues a warning to a user of the pump of an undesirable operating condition, or both, based on a comparison of an actual torque value and a corrected torque value;
• and compensates the corrected torque value based on a mechanical power offset correction.

• and
• compensating the corrected torque value based on a mechanical power offset correction.
