Top 10 Screw Vacuum Pump Suppliers in China

Introduction to Screw Vacuum Pump

A screw vacuum pump is a type of dry vacuum pump that uses two screw rotors to create a vacuum. The rotors are precisely machined and rotate in opposite directions within a housing. As the rotors turn, they trap and compress gas from the inlet and discharge it at the outlet. This design offers several advantages over other types of vacuum pumps. It has a high pumping speed, good vacuum performance, and is suitable for a wide range of applications, including chemical, pharmaceutical, food processing, and semiconductor industries. The dry operation of screw vacuum pumps eliminates the need for oil or other working fluids, reducing the risk of contamination and making them more environmentally friendly.
