Other methods of priming the pump
You can also use these methods in order to prime the pump:
• Prime by ejector
• Prime by automatic priming pump
Start the pump
WARNING:Immediately observe the pressure gauges. If discharge pressure is not quickly attained, stop
the driver immediately, reprime, and attempt to restart the pump.
CAUTION:
• Immediately observe the pressure gauges. If discharge pressure is not quickly attained, stop the
driver, reprime, and attempt to restart the pump.
• Observe the pump for vibration levels, bearing temperature, and excessive noise. If normal levels
are exceeded, shut down the pump and resolve the issue.
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
discharge 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 problem.
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.
Activate the i-ALERT Condition Monitor
WARNING:
Never heat the condition monitor to temperatures in excess of 300°F (149°C). Heating to these
temperatures could result in death or serious injury.
CAUTION:
Always wear protective gloves. The pump and condition monitor can be hot.
