If it is reciprocationg pump keep suction and discharge valve full open
If it ia a centrifugal pump keep the discharge valve close or crank open
If the pump has recycle line then keep recycle control valve full open and then start the pump and slowly open discharge valve by monitoring discharge pressure
Monitor for any abnormal sound
What is the Reciprocating pump start up procedure?
Pump Start-up Procedure
Line up the pump valves.
Ensure that the drain valve is closed.
Open the suction valve.
Open the vent valve to bleed off gases – when liquid comes from the vent valve – close it again. (This is called ‘Priming the pump’).
Open the gland-seal valve (if fitted).
Commission the bearing and oil cooling systems (if fitted).
if an oil bottle or ‘slinger-ring’ reservoir is used for the bearings, ensure it is full and functioning properly.
Check by hand that the pump shaft is freely rotating – (power is OFF at this point).
Energise or, if the rule applies, have the electrician energise, the power supply.
The discharge valve, at this point, should still be closed.
Start the pump motor. Check that the pump is rotating in the correct direction.
Check that the discharge pressure is steady – if not check at the vent and release any further trapped gas.
Check for vibration, overheating and/or any undue noise from the pump, bearings or coupling.
Re-check the lube and cooling systems and check for leaks at the pump glands. (With the ‘packed’ type gland seal, a slight leakage is desirable for lubrication and cooling of the gland). Open the discharge valve
Report to control room that the pump is in operation and all is O.K. (If not O.K. -shut down the pump and have the control room operator call a maintenance mechanic).
