•
To avoid risk of equipment damage, observe the pump for vibration levels, bearing tem-
perature, and excessive noise. If normal levels are exceeded, shut down the pump and
resolve the issue.
•
On frame mounted units, ensure that the oil level is correct prior to starting pump. Close
coupled pumps do not have oil lubricated bearings.
NOTICE:
Risk of equipment damage on pure or purge-oil mist-lubricated units. Remove the viewing port
plugs to verify that oil mist is flowing properly. Reinstall the plugs after confirming.
Before you start the pump, you must perform these tasks:
•
Open the suction valve.
•
Open any recirculation or cooling lines.
1.
Fully close or partially open the discharge valve, depending on system conditions.
2.
Start the driver.
3.
Slowly open the discharge valve until the pump reaches the desired flow.
4.
Immediately check the pressure gauge to ensure that the pump quickly reaches the correct dis-
charge pressure.
5.
If the pump fails to reach the correct pressure, perform these steps:
a) Stop the driver.
b) Prime the pump again.
c)
Restart the driver.
6.
Monitor the pump while it is operating:
a) Check the pump for bearing temperature, excessive vibration, and noise.
b) If the pump exceeds normal levels, then shut down the pump immediately and correct the prob-
lem.
A pump can exceed normal levels for several reasons. See Troubleshooting for information about
possible solutions to this problem.
7.
Repeat steps 5 and 6 until the pump runs properly.
