Each Teikoku Canned Motor Pump comes with the patented Teikoku Rotary Guardian (TRG) an electrical meter that continuously monitors both axial and radial wear. The TRG indicates any serious malfunction of the pump before a failure occurs; many users opt to have the TRG connected to an alarming device.

The progress of bearing wear and any incorrect rotor position is continuously indicated.

Bearing monitor is in 0.0 - 0.5 (Green) Range
This indicates that bearing wear is still within accepatble limits. The pump is in normal operation.

Bearing monitor is in 0.5 - 0.75 (Yellow) Range
This indicates increased wear on bearings. Shortly, the pump shall be maintained and bearings replaced.

Bearing monitor is in 0.75 - 1.0 (Red) Range
Faulty bearings in pump. Immediately replace bearings to avoid severe damage to the pump.

TRG monitor is past 1.0 (Red) Range
Reverse pump motor rotation direction. Immediately stop pump operation and reverse leads.
