Fundamentals of Vacuum Pumps (High Vacuum)
Screw Pump
What is a Dry Screw Vacuum Pump?
Dry Screw Vacuum Pump has two parallel screw-shaped rotors precisely tolerating each other. The pump's cylinder transfers and compresses gasses continuously in the direction of the screw axis.
There are some screw rotors shape types such as rectangular, spiral, lysholm, and so on.
| Advantage | Disadvantage |
| Enables continuous operation from atmospheric to ultimate pressure. | Single-stage compression creates high internal temperatures, which may create intake gas restrictions. |
