Screw pump EXS750/4200
The EXS screw pump uses the same technology as the GXS screw pump and is designed to integrate our market-leading technology advantages into complete equipment that focuses on simplicity and durability. With better performance, simple control concepts and low maintenance costs, EXS pumps will operate reliably for many years to come. Our EXS series dry screw vacuum pumps are available in EXS450, EXS750 and EXS750/4200 models. Mainly used in metallurgy, plasma processing, LED manufacturing, solar energy, coating and other industries.

| Features
1. Rugged and durable design features
Reliable new gas system, equipped with manual gas ballast control device and beautiful metal plate protective shell.
2. Simple electrical strategy
Built-in ready-made inverter simplifies connection and communication. Installation of protective sensors, reliable electrical design, insurance.
3. Low power consumption and low power consumption
Due to low power consumption and low power consumption, EXS has very low carbon emissions. It does not produce waste or dirty engine oil that requires special disposal, which is also beneficial to the environment.
4, improved rough pumping speed, improved low pressure performance
faster processing speed, shorter evacuation time, thus higher production efficiency; The ultimate low pressure of the dry screw vacuum pump is reduced to <1 x 10-2, and the combined low pressure of the pump and the booster is reduced to <1 x 10-3.
5. Non-contact long-lasting seal
Non-contact long-lasting seal, equipped with an integrated oil-blocking labyrinth seal, provides effective sealing performance.
6. Advanced core technology
Advanced high-quality bearings and special oils with low vapor pressure ensure application compatibility.| Purpose1. Metallurgy: vacuum brazing, electron beam welding, nitro carbonization, low pressure nitriding, low pressure carbonization, carbon vapor impregnation, sintering, metal injection molding, Precision investment casting, vacuum arc refining, molten steel degassing,
2, plasma processing: plasma welding, plasma nitriding, vacuum chamber evacuation
3, space simulation cabin: gas recovery/circulation, load fixing cabin
4, LED manufacturing
5, solar energy: silicon crystal drawing, photovoltaic lamination
6, coating: Roller coating/winding coating, hard coating (CVD/DLC), surface activation, plasma spraying, glass coating -
