Diaphragm pumps are positive displacement pumps that use a flexible diaphragm to move fluids, creating a vacuum to draw in and expel liquid or gas. They are highly versatile, capable of handling viscous, abrasive, or chemically aggressive fluids without damaging the pump. Known for their ability to run dry and self-prime, diaphragm pumps are widely used in industries such as chemical processing, food and beverage, pharmaceuticals, and wastewater treatment. Their simple design, reliability, and ability to handle solids make them an excellent choice for demanding applications.
