A diafragmapump, also known as a diaphragm pump, is a positive displacement pump that uses a flexible diaphragm to move fluid. The diaphragm is typically made of rubber or plastic and is attached to a connecting rod. As the rod moves back and forth, it causes the diaphragm to flex, creating a pumping action.

The operation of a diaphragm pump involves two chambers, each equipped with check valves. In one chamber, the diaphragm moves away from the pump casing, increasing the volume and drawing fluid in through the inlet valve. Simultaneously, the diaphragm in the other chamber moves towards the casing, decreasing its volume and forcing fluid out through the outlet valve. The two chambers operate in an alternating sequence, ensuring a continuous flow of fluid.

Diaphragm pumps are known for their ability to handle a wide range of fluids, including those with high viscosity, solids, or abrasive particles. They are also capable of operating dry without sustaining damage, making them suitable for applications where the fluid supply may be intermittent. Their simple design with few moving parts contributes to their reliability and ease of maintenance.

Common applications for diaphragm pumps include chemical processing, water treatment, food and beverage production, and the transfer of slurries and viscous materials. They are often chosen for their ability to provide a gentle pumping action, which is important for shear-sensitive fluids. The materials used in their construction can be selected to ensure compatibility with corrosive or aggressive chemicals.
