• ### Pump theory - ScienceDirect

1. All pumps use basic forces of nature to move a liquid. As the moving pump part (impeller, vane, piston diaphragm,etc.) begins to move, air is pushed out of the way. The movement of air creates a partial vacuum (low pressure) which can be filled up by more air, or in the case of water pumps, water.

2021-1-15 · However, centrifugal and diaphragm pumps do not actually suck water so much as they raise or lift it with help from mother nature. Water, like electricity, will always flow along the path of least resistance. In order to lift water the pump must provide a path (area of low pressure or low resistance) to which the water will naturally seek to flow.

• ### Basic pump theory - step 2 for beginners

Because the impeller moves fast, the centrifugal force compresses the water against the outside of the blade. This pressure causes the water to rocket forward in a high-speed jet out of the impeller. This speed creates pressure on the outlet side of the pump, pushing the water through the pipe.
