A diaphragm water pump works follows the same principles as the engine cylinders of a vehicle.

Inside the pump there is a diaphragm made of a rubber or plastic material. As the diaphragm bends, the pressure inside the pump decreases, attracting the fluid. Depending on the water pump, the diaphragm can use different bending methods.

When the diaphragm moves backwards, the liquid is ejected from the pump to the other side, continuing to feed and discharge the liquid to be pumped.

Many diaphragm water pumps have non-return valves to prevent liquid from flowing back into the pump.

Another helpful comparison to help you understand how a membrane water pump works is to compare the appearance of the membrane in your body. These pumps work according to a similar principle to that used by the body to breathe.

The diaphragm is a muscle that is located under the lung and contracts, causing the lung to expand. As it expand, the air pressure in the lungs decreases. The result is inhalation.

When the diaphragm relaxes, the lungs contract and the person releases air. Similarly, the diaphragm in these pumps pushes the liquids inwards and outwards, except that the liquid does not escape in the same way as it entered.

One of the advantages of a diaphragm water pump is its ability to pump a wide range of liquids, including highly viscous ones. Diaphragm pumps are versatile because they work well, even when pumping against high pressure or the so-called head.

They can also be used for pumping corrosive chemicals because the diaphragm is made of reaction resistant materials such as Teflon.

Diaphragm water pumps can be operated with compressed air, whereby air is applied on one side of the diaphragm and the liquid to be pumped is sealed on the other side. Others can use electric motors or mechanical means to move the diaphragm and generate force.
