Start-up procedure of pump commissioning

Check pump: Maintenence: Done, work permit close, and power back from Substation. Panel: There is no alarms. Inform: Inform DCS Operator before start up the pump and be on touch with Control room. Level: Check Level, must be over Low level. if you start pump with low level or without level Cavitation will happen, but now almost all pumps have an Interlock device tp protect it and won't start in Low Level. Be sure: Discharge Valve Must be fully close before start pump, To avoid Motor Over current, and Suction valve must be fully open. Open Vent and wait to fill pump casing until the flow comes out without air, then close vent. Now you are ready to start pump but the important thing is to inform DCS operator that you finished the priming, then push Start Putton. After pump runing Check abnormal sounds or Hi vipuration and Discharge Pressure if every thing OK now Inform DCS Operator to Open Discharge Vale, then open it Gradually. I hope these can help you....
