Strong chemical corrosion resistance
● The corrosion-resistant vacuum pump uses a special diaphragm (the surface of the diaphragm is compounded with PTFE coating) and pump head design, including all joints and pipelines, to ensure that the parts in contact with the gas are imported PTFE materials, so it can withstand most corrosive gas;
● At the same time, the electrical switches and casings are also treated with anti-corrosion treatment, especially the transmission mechanism and circuit parts are made of corrosion-resistant materials to form a closed space, which is completely isolated from the external environment, so that the vacuum pump is not only resistant to corrosive media, but also suitable for corrosive environments. , completely solve the problem of chemical corrosion resistance of vacuum pump;
● Professional multi-channel sealing system design, high elastic PTFE material diaphragm, with high temperature resistance, corrosion resistance, long service life and other characteristics, more than double the service life of domestic similar manufacturers' products, reducing user maintenance costs.

No pollution, no maintenance
● The diaphragm vacuum pump can realize the complete recovery of the solvent, eliminate the pollution of toxic and harmful organic solvents to the environment and the health hazards of the operators and nearby personnel, and even the mixed solvent can be highly recycled; the diaphragm pump is an oil-free dry The pump makes the laboratory clean and quiet, and users do not need to regularly clean, change pipes, change water and other maintenance work, and the diaphragm vacuum pump is 105% maintenance-free;
Low noise, low vibration, low temperature rise
● The corrosion-resistant vacuum pump adopts electric motor direct-drive power transmission without intermediate transmission parts, coupled with the characteristics of low stroke, low noise and low temperature rise of the diaphragm, which makes the instrument run stably, with little loss, and ensures the safe operation of the instrument;

Overheating protection
● Each product is equipped with a temperature protection switch. When the internal temperature of the body is too high, it will automatically stop, and then it will start automatically after the temperature cools down to ensure the stability and safety of the system.
