5.14 Prime with an automatic primer pump
This system works well in situations where there is a fluctuating suction lift that occasionally drops below
the normal limits of the pump. The system also works well where there is any quantity of air entrained in
the pumped fluid.
1.
Install a vacuum tank with a vacuum gauge near the primer pump.
2.

WARNING:
Risk of equipment damage, seal failure and breach of containment. Ensure all flush and cool-
ing systems are operating correctly prior to starting pump.
NOTICE:
•
Risk of equipment damage due to dry operation. Immediately observe the pressure
gauges. If discharge pressure is not quickly attained, stop the driver immediately, reprime,
and attempt to restart the pump.
•
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.
