When water is supplied to the pump outlets and pipelines, air accumulations in the system narrow the passage area of the water and cause a decrease in productivity. Single-ball and double-ball suction cups are used to prevent this negative process. The air formed in the system fills the suction cup before the water and is thrown out through the hole in the lid. The suction cup is then filled with water and lifts the ball up, at which point the holes are closed and sealed.
