Product Description

Dry Screw Vacuum Pump is composed of a pair of screw rotors meshing in the opposite and synchronous way in the pump casing to form the suction and discharge operations. By using the maintenance-free technology, our screw vacuum pump has fewer problems about the difficulty and high cost of maintenance. Without any lubricants and sealing liquid in the pump housing, screw vacuum pumps can be used to recycle many condensable gases. This feature can solve the pollution and eco-issues of many vacuum systems such as the steam-jet pumps, slide valve pumps, rotary vane pumps and liquid ring pumps, meanwhile the recycled materials can create additional economic benefits for clients.
