Introduction to Diaphragm Pumps
Diaphragm pumps, also known as membrane pumps, are positive - displacement pumps that use a flexible diaphragm to transfer fluids. The diaphragm moves back and forth, creating a change in volume within the pump chamber. This action alternates between drawing fluid into the chamber and then expelling it out. Diaphragm pumps are widely used in various industries such as chemical, food and beverage, pharmaceutical, wastewater treatment, and mining due to their ability to handle a wide range of fluids, including corrosive, abrasive, and viscous substances. They are self - priming, can operate dry without damage in some cases, and offer accurate flow control.
