Teikoku Electric Pump F250-8028A4BM-1012P1AV

Open vent valve slowly and pay attention to liquid, especially for toxic or high temperature liquid

Complete priming in the following order

Bleed air from the air vent valve (36)

If handling a dangerous liquid, did you pay full attention to air venting?

For R & RA-type pumps, are all valves in reverse circulation piping opened?

TRG Bearing Wear Monitor Inspection

Check the TRG meter during operation

Determine bearing changing intervals using color coding system if initial TRG reading is not recorded

Use color change (Green, Yellow, Red) as a reference to check bearing wear

Is the TRG reading increase 0.3 or more (Yellow)?

Stop the pump and check bearings if TRG reading is Yellow

Do not operate if TRG meter condition is RED

Check if TRG meter is in Green zone (0 to 0.5)

Verify specified media and capacity are used for heating/cooling jacket and heat exchanger

Is the temperature of the coolant less than 35°C (95°F)?

Ensure coolant flow order for B plan

Enter the coolant flow rate for Motor Jacket (l/m)

Enter the coolant flow rate for Heat Exchanger (l/m)

Is the coolant flow rate for Motor Jacket within the specified range?

Check that valves in reverse circulation piping are opened (for R & RA-type)

Meter overscale: Pump rotates in reverse direction — correct connection of electrical terminals

Inspect the following points for the bearings

Is there any issue with the inspected points?

Bearing Removal and Replacement

Remove the Set Screw (48) and take out the bearing

Select the motor frame for wear limit check

Enter the measured øA-øB value (mm)
