Product Features
It can run at full speed under atmospheric pressure and ultimate vacuum.
A single stage can achieve a higher vacuum degree, with an ultimate pressure of 2-5Pa.
There is no oil or water in the working chamber of the pump that contacts the process gas.
The rotors do not touch each other, reducing wear; the rotors, housings, and flow-through parts can be coated with anti-corrosion coatings such as Teflon and Hastelloy.
The gas channel in the pump is short and can be exhausted quickly.
It can be operated alone or as a fore-stage pump.
Dry screw vacuum pumps are available in two types: equal pitch and variable pitch, also known as external compression screws and internal compression screws. Compared with equal pitch screws, variable pitch screw pumps have lower exhaust temperature and higher efficiency.
