When the water hits the rotating impeller, energy of the impeller is transferred to the water, forcing the water out (centrifugal force). The water is displaced outward, and more water can now enter the suction side of the pump to replace the displaced water.
How Do Water Pumps Work?
Water pumps are essential pieces of equipment that are used in a variety of applications from agricultural irrigation to industrial processes. Understanding how water pumps work is important for maintaining their efficiency and to determine the best type of pump for a particular situation.
Water pumps are typically classified as either centrifugal pumps or positive displacement pumps. Centrifugal pumps use a rotating impeller to draw water into the intake and then use centrifugal force to create a pressure differential that propels the water out of the discharge pipe. Positive displacement pumps, on the other hand, use a piston or diaphragm to draw water in through an intake and then force it out through a discharge pipe.
The most common type of water pump used in residential and commercial applications is the centrifugal pump. These pumps use a rotating impeller to draw the water in through the intake and then spin the impeller to create a pressure differential that forces the water out of the discharge pipe. The pressure differential is created by the spinning of the impeller, which creates a vacuum in the intake and a pressure in the discharge. The pressure in the discharge is greater than the pressure in the intake, creating a pressure differential which forces the water out of the pump.
