3. Check that the pump draws by freeing the suction as close as possible to the pump:
a) if the pump does not draw despite being sufficiently full of priming water
1. Tighten the bolts and pipe accessories on the suction side.
2. Check the voltage to ensure that the pump is rotating at the correct speed.
3. Open the pump and check that nothing is blocking it inside,
4. Set a priming speed that is fast enough
5. Clean the filter and try again
6. Replace the mechanical shutter.
b) Try priming in re-circulation mode. If the pump is drawing normally, check the suction pipe and strainer which may be
blocked or be allowing air to enter.
E) Noisy pump, check
1. That no air is entering the suction side and causing dull crackling in the pump.
2. That there is no cavitation caused by insufficient diameter or a restriction in the suction tube. An over-sized discharge
pipe can also cause cavitation. Use pipes of the correct size or purge the pipes if necessary.
3. That no vibration is occurring due to incorrect fitting.
4. That there are no foreign bodies in the pump housing.
5. That the motor bearings have not seized due to excessive clearance, rust or prolonged overheating.
