The GCD Series direct drive, oil rotary vacuum pump is corrosion resistant making it an ideal pumping solution for toxic and corrosive gases. Three different sizes are available from 50 to 200 L/min.
Features
- Chemical type of Oil rotary pump with surface treatment on the gas contact surface.
- Connectable to oil filtration system.
- Low noise and low vibration.
- The backflow prevention mechanism prevents oil from flowing back to the vacuum chamber when it is stopped due to a power failure.
- The exhaust speed is stable due to the installation of the forced oil supply mechanism.
- Operation from atmospheric pressure is possible.
- Easy connection with flanged parts and connection by knock pins on internal parts.
