Introduction to Diaphragm Pumps
A diaphragm pump is a positive - displacement pump that uses a flexible diaphragm to move fluid. The diaphragm moves back and forth, creating a change in volume within the pump chamber. As the diaphragm moves away from the inlet valve, it creates a vacuum that draws fluid into the chamber. When the diaphragm moves towards the outlet valve, it compresses the fluid and forces it out of the pump.
Diaphragm pumps are known for their versatility, reliability, and ability to handle a wide range of fluids, including corrosive, abrasive, and viscous substances. They are widely used in various industries such as chemical processing, food and beverage, pharmaceuticals, and wastewater treatment.
