What is diaphragm pumps?

Diaphragm pumps (also known as membrane pumps) are positive displacement pumps that use a diaphragm to move fluid. The diaphragm, typically made of rubber, thermoplastic, or Teflon, reciprocates, creating a pumping action. They are commonly used for pumping a wide variety of fluids, including abrasive, corrosive, and viscous materials. Common applications include chemical processing, wastewater treatment, and food and beverage production. They are valued for their ability to handle solids and for their self-priming capabilities.
