Teikoku Electric Pump F50-3213A4BM-0304P1AV

Check discharge pressure frequently during operation

Ensure pressure is stable in a non-variable closed loop

Check motor amps at normal operations

Verify motor amps are within the expected range

Confirm pump is not operating above the rated full load amps listed on the nameplate

Check for excessive air or vapor in the liquid supply

Stop the pump and vent all accumulated vapor if large fluctuations are observed in the discharge pressure gauge

Stop the pump if any abnormal noise or vibration is observed and check for possible causes (see Appendix A: Troubleshooting)

Shaft Sleeve (17) and Thrust Collar (18) Inspection

Inspect for contact marks or wear

Are there any other contact marks or wear?

Ensure all parts are fastened correctly

Check the tightness of every fastener

Re-tighten all bolts before use

Is this the initial installation?

Filter and Circulation Pipe Inspection

Inspect Filter (03) and Circulation Pipe (34) for blockages or clogs

Does this apply to F and FA plan pumps with circulation pipe construction?

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)
