Introduction to Diaphragm Pump
A diaphragm pump is a type of positive - displacement pump that uses a flexible diaphragm to move fluid. The diaphragm oscillates back and forth, creating a change in volume within the pump chamber. This volume change causes the fluid to be drawn into the chamber during the suction stroke and then pushed out during the discharge stroke. Diaphragm pumps are known for their versatility, as they can handle a wide range of fluids, including corrosive chemicals, viscous liquids, and abrasive slurries. They are also self - priming, can operate dry without damage for short periods, and offer good suction lift capabilities. These features make diaphragm pumps popular in various industries such as chemical processing, food and beverage, pharmaceuticals, water treatment, and mining.
