Top 10 Diaphragm Vacuum Pump Manufacturers in China 2026

Introduction to Diaphragm Vacuum Pumps

Diaphragm vacuum pumps are a type of positive - displacement pump that use a flexible diaphragm to create a vacuum. The diaphragm moves up and down, changing the volume of the pumping chamber. When the diaphragm moves down, the volume of the chamber increases, creating a low - pressure area that allows gas to enter the chamber. When the diaphragm moves up, the volume decreases, and the gas is expelled from the chamber. These pumps are known for their oil - free operation, which makes them suitable for applications where oil contamination is a concern, such as in the pharmaceutical, food, and semiconductor industries. They are also relatively quiet, have a long service life, and are easy to maintain.
