Condensate returns flow into the receiver tank.
The pump chamber fills up with water, but the pump remains off. [This action occurs inside the pump and is not shown here. Refer to various pump style simulations.]
The water level rises in the receiver tank from the returning condensate causing the float to rise.
At the HIGH water level setting, the float switch sends a signal to turn ON the pump.
The water in the pump chamber is forced upward into the eye of the pump's impeller which is rotating clockwise. Centrifugal force pushes the water out along the blades of the impeller and through the pump discharge. [This action occurs inside the pump and is not shown here. Refer to various pump style simulations.]
Condensate is pumped out of the receiver tank causing the water level to fall.
At the LOW water level setting, the float switch sends a signal to turn OFF the pump. With the pump off, the water level will begin to rise again and the fill/pump cycle repeats.
