| Features
1. Overview of functions and advantages
2. Advanced shaft seal technology
The GXS uses innovative technology inside to protect the gearbox from pollution and keep the vacuum chamber oil-free. Non-contact permanent seals ensure efficient sealing performance for reliable pumping performance.
3. Smart pump with stable and trouble-free output
Smart onboard control panel allows you to automatically control the production process, with automatic start-stop routines, power saving, green mode AUC and self-cleaning function options.
4. Advanced pumping mechanism design
GXS is a silent power equipment; updated technology and design can ensure low vibration and quiet operation, which is ideal for sensitive working environments. The enhanced screw rotor enables progressive compression, which improves thermal control and optimizes pumping at each stage of the process.
Long-lasting bearing, long-term lubrication
uses oil to lubricate the gear, which can extend the service life and save maintenance costs, without grease and maintenance.| Purpose1. Metallurgy: metal injection molding, vacuum brazing, vacuum sintering, molten steel degassing, low pressure nitriding (carbon)
2. Vacuum coating: winding coating, hard coating (CVD/DLC), surface activation, plasma spraying, glass coating
3, drying: freeze drying, capacitor drying, lithium battery drying, pipe drying,
4, plasma process: plasma welding, plasma carburizing, plasma cleaning -
