8.9 Priming
Attention: if the pump does not prime, do not operate it for more than 2 minutes to avoid
overheating the liquid and damaging the seal. If the pump does not prime, read paragraph
Engine driven pumps should be brought up gradually to running speed. Never change the accelerator
limit stop: at speeds higher than that for which the engine is set, the pump would absorb more power
than the engine can supply.
Never exceed the maximum speed shown on the pump name plate.
When the pump has primed:
1. Check the shaft seal for leaks.
2. Check that the current absorbed by the motor does not exceed the rated value shown on the
name plate.
3. If the pump does not seem to be operating normally, it must be stopped and the cause found
in troubleshooting section.
