CAUTION:
When a cartridge mechanical seal is used, ensure that the set screws in the seal locking ring
are tightened and that the centering clips have been removed prior to startup. This prevents
seal or shaft sleeve damage by ensuring that the seal is properly installed and centered on the
sleeve.
NOTICE:
•
Verify the driver settings before you start any pump. Refer to the applicable drive equip-
ment IOMs and operating procedures.
NOTICE:
You must follow these precautions before you start the pump:
•
Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order
to prevent premature failure at initial startup.
5.1.1 Prepare for startup
WARNING:
•
For the VSS motor, do not check the motor rotation unless the motor is bolted to the
pump and the driver hub is disconnected from the pump hub.
•
Do not test the motor for direction of rotation when it is coupled to the pump. If the pump
is driven in the wrong direction, serious damage to the pump, motor, and personnel could
result.
Consult the applicable manufacturer instructions for detailed information for the prime mover (electric
motor, engine, or steam turbine), coupling, drive shaft, gear-head, or mechanical seal.
1.
Confirm that you have completed these procedures:
a) Connected the driver to a power supply.
b) Verified that the driver rotates counterclockwise when viewed from above.
c)
Checked the alignment between the pump and driver.
d) Adjusted the impeller.
e) Attached the mechanical-seal lock collar to the shaft.
2.
Verify that the mechanical seal is properly lubricated and that all piping to the seal is connected.
3.
Verify that all cooling, heating, and flushing lines are operating and regulated.
4.
Verify that all connections to the driver and starting device match the wiring diagram.
5.
Verify that the voltage, phase, and frequency on the motor nameplate agree with the line current.
6.
Rotate the shaft manually to make sure that the impellers are not binding.
7.
Verify that the driver bearings are properly lubricated and check the oil level in the housing.
8.
Verify that the auxiliary seal components are properly vented.
9.
For flush water lubricated lineshafts, see the instructions on General Arrangement Drawing.
