high motor amps on 963 coal mills

What causes a motor to draw higher than normal amps | AMP ...

Because this motor draws too high of amps we can only run 2 motors/pumps at a time. We have pulled the pump and trimmed the impeller to reduce pumping capacity to lower the amp draw but it did not change the amp draw at all. The talk now is to swap motor "A" for motor "C" and see if the amp problem follows the motor or stay with the pump.

High Amperage problem with centrifugal pump motors | AMP ...

The product is hydrocarbons. The motor sizing is already checked by the pump vendor for undersizing. The product specific gravity has been checked and found according to the pump design. The pumps performance is OK. The only problem we are facing is that the motors are taking high amperes, i.e. running on overload.
