DRY SCREW PUMP GSD series Dry Screw Vacuum Pump System
Features:
· 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.
· Double-ended bearing support design for reliable rotor support, extremely low vibration and superior starting reliability,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 maintenance 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.
