diaphragm pump
Quick Summary
A diaphragm pump is a type of pump that uses a flexible diaphragm instead of a piston to move fluids. This design is similar to a piston pump, but the diaphragm's pulsation replaces the piston's back-and-forth motion.12
Diaphragm pumps are beneficial because they eliminate the need for piston packings that come into contact with the fluid being pumped. They are useful for handling liquids with solid particles, as well as expensive, toxic, or corrosive chemicals where leaks must be prevented. These pumps can operate dry for extended periods, and their pumping rate can often be adjusted during operation.2
