Product Description

GSD300B(D) 300m³/h Oil-Free Dry Screw Vacuum Pump 


*Constant lead screw

*All B-type series screw vacuum pump is with base plate, frequency convertor, silencer, check valves.

*Based on the B-type,  all D-type series products have addirional sheet metal housing and electrical controls.


Features and Benefits



*Efficient rotor profile design with the high ultimate pressure.

*Oil-free, clean vacuum, combine with roots pump for system.

*Good geometrical symmetry, low noise, long working life.

*remove condensable steam, dust, toxic and other gases, and will not be trapped in the pump chamber.

*Double-ended bearing support design for reliable rrotor support, extremely low vibration and superior starting reliablity, especially for special demanding process.

*Combined with lip-style seal and labyrinth oil-repellent structure to achieve strong sealing performance and long service life, with nitrogen purging to prevent gear box from the pollution of process medium to achieve oil-free vacuum environment.

*High-efficiency permanent magnet synchronous motor with frequency converter to maximize torque output for harsh processing demand water-cooled integral sealed motor design to eliminate oil leakage to improve operational reliability, extend service life and reduce maitenance costs.

*Intelligent control system design to realize the one-button start and stop by using intelligent program. The pump chamber can be automatically cleaned during shut down, and the remote control and monitoring functions can be realized through the external control I/O interface and RS485 interface (Modbus protocol).

*Compact-size, few parts, few spares, stable running, light weight, small size, easy installation.
