2-3.4. Bearing Wear Monitor
The Dynapump LE Series patented Teikoku Rotary
Guardian (TRG) takes the mystery out of pump reli-
ability by continuously monitoring the critical running
clearances between the rotating and stationary com-
ponents. The TRG is mounted on the electrical junc-
tion box as standard.
The TRG meter operates on the principle of induced
voltage. Electric coils are embedded in the stator
windings and an electric current is produced with
the rotation of the rotor assembly. When the rotor is
perfectly centered in the stator between the coils the
electric currents are balanced and no voltage is de-
tected. When bearing wear occurs the rotor moves
toward one coil and away from the other producing a
low voltage that is indicated by the TRG meter. As
this gap becomes larger the voltage increases. The
TRG should be monitored frequently to determine
the condition of the pump.

The TRG METER is color coded for easy recogni-
tion:
- Green = Normal operation.
- Yellow = Pump should be scheduled for
maintenance.
- Red = Pump should be shut down and
removed for maintenance.
There is no requirement for resetting of the TRG af-
ter replacement of worn components. Once the
worn components are replaced and the pump is re-
turned to service, the TRG meter will return to the
Green position.
The TRG has been designed to accommodate a va-
riety of output options and can be configured to match
existing or future plant instrumentation without sig-
nificant modification.
