Analysis of the reason of the sudden stop of the self priming pump:
1. The pump head is too high, the current regulation; the outlet valve, reducing the current flow driving
2. The impeller or pipeline blocked; check the barrier.
3. Air or entrance pipeline leakage inspection; entrance pipeline has no cavitation and / or air leakage.
4. Stuffing box packing or seal wear, so that the air leakage into the pump casing; check the packing or seal and the need to replace. Check if the lubrication is normal.
5. Pumping hot or volatile liquid inhalation of low flow; increase the suction head, to consult manufacturers.
6. Pump casing sealing gasket damage; check the situation of the gasket and according to the requirements of the replacement.
7. Valve entrance pipe or the immersion depth is not enough; the right to consult manufacturers immersion depth, eliminate swirl baffle.
