Product Overview:

VB The series corrosion-resistant vacuum diaphragm pump is a double-stage pump with a medium of gas. All parts in contact with the gas are polytetrafluoroethylene. (PTFE) The material has a high corrosion resistance and a wide range of application. It can completely replace water circulation pumps. It is suitable for the treatment of corrosive gases in chemical, pharmaceutical, petrochemical and other industries, such as suction filtration, reduced pressure distillation, rotary evaporation, vacuum concentration, centrifugal concentration, solid phase extraction, etc.

Main features:

Resistant to chemical corrosion

● Corrosion-resistant vacuum pump uses special diaphragm (Diaphragm surface composite  PTFE  coating )and pump head design, including all joints and pipelines, ensure that the parts in contact with the gas are imported PTFE Material, therefore resistant to most corrosive gases；

● At the same time, the electrical switches and shells are also corrosion-proof, especially the use of corrosion-resistant materials for the transmission mechanism and circuit parts to form a closed space, which is completely isolated from the external environment, so that the vacuum pump can not only resist corrosion medium, but also perfectly suitable for corrosive environments, completely solving the chemical corrosion resistance of the vacuum pump;

● Professional multi-channel sealing system design, high elasticity PTFE The material diaphragm has the characteristics of high temperature resistance, corrosion resistance and long service life. It is more than twice the service life of products from similar domestic manufacturers, reducing user maintenance costs.

No pollution and maintenance-free

● Diaphragm vacuum pump can achieve complete solvent recycling, eliminate the pollution of toxic and harmful organic solvents to the environment and the health of operators and nearby people. Even mixed solvents can be highly recycled and utilized.； The diaphragm pump is a dry pump without water and oil, making the laboratory clean and quiet. Users do not need to regularly clean, change pipes, water changes and other maintenance work. The diaphragm vacuum pump is 100% maintenance-free;

Low noise, low vibration, low temperature rise

● Corrosion-resistant vacuum pump adopts direct drive power transmission of motors, without intermediate transmissions, and the diaphragm has low stroke, low noise, low temperature rise and other characteristics, making the instrument stable operation and small loss, ensuring safe operation of the instrument；

Overheating protection

● Each product is equipped with a temperature protection switch. When the internal temperature of the machine is too high, it will automatically stop and wait for the temperature to cool down before starting it on its own to ensure the stability and safety of the system's work;
