How does a pool pump work?
Pool pumps are self-priming centrifugal pumps; they have a vacuum chamber, which must be filled with water in order for the pump to create a vacuum, resulting in the pump pulling the water out of the pool. When we turn on the pump the motor will begin to rotate on high speed. The motor drives the pump impeller, located inside the pumps center at the opposite end, away from the electrical switch portion of the motor. While the motor is rotating, the tips of the impeller are sealed hydraulically inside of the pump diffuser, this allows self-priming to occur and the diffuser eliminates any air coming into the pool hence we see bubbles returning to the pool.
