Pneumatic diaphragm pump in filter press

what's the pneumatic diaphragm pump?

A pneumatic diaphragm pump is a type of positive displacement pump that uses compressed air to move a flexible diaphragm back and forth, creating a vacuum that draws in fluid and then forcing it out through the discharge port. The diaphragm separates the air from the fluid, preventing contamination of the pumped material. These pumps are commonly used in industries such as chemical processing, food and beverage, and wastewater treatment. They are known for their reliability, versatility, and ability to handle a wide range of fluids, including abrasive and viscous materials.
