Product Details

Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Product Overview:
HC series corrosion-resistant vacuum diaphragm pump is a two-stage pump with gas medium. All parts in contact with gas are made of polytetrafluoroethylene (PTFE). It has high corrosion resistance and wide application range. It can completely replace water circulation pump. It is suitable for the treatment of corrosive gases in chemical, pharmaceutical, petrochemical and other industries, such as suction filtration, vacuum distillation, rotary evaporation, vacuum concentration, centrifugal concentration, solid phase extraction, etc.
Key features:
Strong chemical corrosion resistance
● The corrosion-resistant vacuum pump uses a special diaphragm (PTFE coating on the surface of the diaphragm) 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 resist most corrosive gases. At the same time, the electrical switches and housings are also treated with corrosion prevention, especially the transmission mechanism and circuit parts are completely isolated from the external environment by using corrosion-resistant materials, the vacuum pump can not only resist corrosion medium, but also be perfectly suitable for corrosive environment, which completely solves the problem of chemical corrosion resistance of vacuum pump;
No pollution, no maintenance
● Diaphragm vacuum pump can realize complete solvent recovery, eliminate toxic and harmful organic solvent pollution to the environment and harm to the health of operators and nearby personnel, and even mixed solvents can be highly recycled. Diaphragm pump is a dry pump without water and oil, which makes the laboratory clean and quiet. Users do not need regular cleaning, pipe change, water change and other maintenance work. Diaphragm vacuum pump is 100 maintenance-free;
Low noise, low vibration
● Corrosion resistant vacuum pump adopts motor direct drive power transmission, no intermediate transmission parts, coupled with the diaphragm low stroke, low noise characteristics, so the product noise can be kept below 70dB; overheat protection
● Each product is equipped with a temperature protection switch, which will automatically stop when the internal temperature of the body is too high, and then start by itself after the temperature is cooled to ensure the stability and safety of the system;
