•
Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order
to prevent premature failure at initial startup.
6.1.2 Start the 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.
1.
Fully close 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) 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.
7.
Repeat steps 5 and 6 until the pump runs properly.
6.1.3 Initial start-up
Before starting up the pump, check, if the following points were controlled and carried out:
1.
There is no need to lubricate the pump before starting it up.
2.
Pump and suction pipe must be filled completely with liquid when starting up.
3.
Turn pump unit once again by hand and check that it moves smoothly and evenly.
4.
Turn pump unit once again by hand and check that it moves smoothly and evenly.
5.
Check that lantern guard sheets are mounted and that all safety devices are operational.
6.
Switch on any existing sealing or flushing piping. For quantities and pressures refer to data sheet
and / or order confirmation.
7.
Open valve in suction /intake pipe.
8.
Set discharge side valve to approximately 25% of rated flow quantity. With pumps with a discharge
branch rated width less than 200, the valve can remain closed when starting up.
9.
Secure, that unit is electrically connected according to all regulations and with all safety devices.
