Commissioning / Return to Service
WARNING
Before starting up the pump make sure that the following requirements are checked and fulfilled:
1) If the pump has been in long term storage (more than 3 months), ensure proper storage procedures were
followed, including instructions for removing the pumps from storage (see contract documents and/or
contact your GIW / KSB representative). Failure to follow proper storage procedures will void your warranty.
See Section 3.2 "Storage Requirements".
2) For elastomer lined pumps ensure that the piping has been installed and the torqueing of the piping bolts
has been completed. For all metal pumps this step may be completed during Step 5.
3) The impeller nose clearance has been properly set.
See Section 10.4 "Setting Impeller Nose Gap" for details.
4) Pump drive train final alignment is complete.
See Section 5.3.1 "Alignment" for details.
5) Final torquing of all bolts has been completed.
See Section 11.1 "General Torque" for details.
6) All electrical and power supply connections are in order, including fuses and overload protection devices.
See Section 5.1 "Safety Regulations" for details.
7) All required auxiliary connections, such as shaft seal water, oil coolers, etc. are made, tested and ready to
function.
See Section 5.4.1 "Auxillary Connection" for details.
8) All safety guards and equipment are in place.
See Section 5.5 "Safety Guards" for details.
9) Any required instrumentation has been properly installed.
See Section 5.6 "Oil Temperature Monitoring" for details on RTD installation.
10) Bearing assembly lubrication is completed.
See Section 6.1.1 "Bearing Lubrication" for details.
11) Shaft seal is ready for operation.
See Section 6.1.2 "Shaft Seal Commissioning" for details.
12) Drive train direction of rotation at the pump is correct.
See Section 6.1.3 "Checking the Direction of Rotation" for details.
13) The pump set is primed.
See Section 6.2.1. "Priming the Pump"
14) The desired operating conditions do not exceed those allowed by the pump.
See Section 6.4 "Operating Limits" for details.
6.1.1
Bearing Lubrication
CAUTION
Pump bearing units are shipped empty of oil. Before starting the pump, fill them to the center of the oil level sight
gauge using the GIW Blue 150 synthetic bearing oil supplied with the unit. For vertical pumps, fill the oil reservoir.
If locally obtained oil is desired, use an equivalent synthetic or a high quality ISO220 or 320 mineral oil suitable for use
with heavy industrial equipment, anti-friction bearings and oil circulating systems. Such oil typically has high
temperature stability, resistance to oxidation and foaming, and inhibits rust, corrosion, and the formation of deposits.
Oils with EP (Extreme Pressure) additives are not generally recommended. Detailed bearing oil specifications and GIW
Blue replacement oil are available from GIW.
