Teikoku Electric Pump F25-2008A4BM-0102P1AV

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 bearing wear limits

Enter the measured øA-øB value (mm)

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

Open discharge valve for a few seconds and close it again

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?

Ensure all safety precautions are followed

Remove Drain Plug (59) or open drain valve to drain the liquid in the pump

Check for high pressure buildup before opening Air Vent Valve (36)

Remove Circulation Pipe (34) or heat exchanger (B-type)

Insert support under Casing (01) to relieve stress from piping

Remove fixing Bolt (46B) or (46C) of Casing (01) for back pullout disassembly

Remove Bolt (46D) and slide the pump backward on the Base (40)

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

Shut all valves after stopping the pump

Drain the entire pump and connected piping

Ensure pump only contains liquid before restarting if liquid could freeze or crystallize

Confirm if the pump is removed from service for an extended period
