Advantage:
There is no water or oil in the working chamber, and a clean vacuum can be obtained.
The single-stage design ensures that solid waste is more easily discharged and significantly reduces the residue in the pump.
Through special coating treatment, it can be used to extract toxic, corrosive and condensable gases.
Work in a way that does not use oil or water, significantly reducing operating costs.
The sealing mode is mechanical seal & lip seal.
The simple design structure is easy to maintain.
There is no metal contact between screw and pump body and screw, and the service life is long.
Short gas path can make gas discharge quickly.
The screw rotor has higher working efficiency.
Low noise, low vibration.
