Can the waterline be purged directly with unpurified air? After draining the pump, do I need to close both the inlet and outlet and then blow air through it?
Unpurified air is compressed air from which water has not been removed using a dryer, and it is used for general purging and displacement.
Should the centrifugal pump’s water line be blown from the return side or from the inlet side?
For a centrifugal pump, should the water line be connected to the inlet for air intake or to the return flow? Or any of them will work?
For a centrifugal pump, should the water line be connected to the inlet for air intake or to the return flow? Or any of them will work? It won’t cause any damage to the pump, right?
Air is introduced at the water inlet to prevent the impeller from rotating in reverse or even falling off.
The plug on the pump body also needs to be removed
