An alternative to imported products; an all-new design.
Product Overview
The VB series corrosion-resistant diaphragm vacuum pump is a two-stage pump for gaseous media. All gas-contacting parts are made of polytetrafluoroethylene (PTFE), providing high corrosion resistance and a wide range of applications. It can fully replace water circulation pumps and is suitable for handling corrosive gases in the chemical, pharmaceutical and petrochemical industries, including vacuum filtration, reduced-pressure distillation, rotary evaporation, vacuum concentration, centrifugal concentration and solid-phase extraction.
Product Features
Resistance to Strong Chemical Corrosion
The corrosion-resistant vacuum pump uses a special diaphragm with a composite PTFE surface coating and a specially designed pump head, including all fittings and tubing. All gas-contacting parts are made of imported PTFE, providing resistance to most corrosive gases;
- The electrical switches and housing also receive anti-corrosion treatment. In particular, corrosion-resistant materials enclose the drive mechanism and circuitry in a sealed space isolated from the external environment. The vacuum pump can therefore handle corrosive media and operate in corrosive environments, fully addressing chemical corrosion resistance;
- A dedicated multiple-seal system and highly elastic PTFE diaphragms provide high-temperature resistance, corrosion resistance and a long service life. The service life is more than twice that of comparable products from domestic manufacturers, reducing users’ maintenance costs;
Pollution-Free and Maintenance-Free
- The diaphragm vacuum pump enables complete solvent recovery, eliminating environmental pollution from toxic and harmful organic solvents and the health hazards they pose to operators and nearby personnel. Even mixed solvents can be recovered to a high degree for reuse. This water-free, oil-free dry pump keeps the laboratory clean and quiet. Users do not need routine cleaning, tubing replacement, water changes or similar maintenance: the diaphragm vacuum pump is 100% maintenance-free;
Low Noise, Low Vibration and Low Temperature Rise
- The corrosion-resistant vacuum pump uses direct motor drive without intermediate transmission components. Combined with the diaphragm’s short stroke, low noise and low temperature rise, this provides stable operation, low wear and safe instrument operation;
Overheating Protection
- Each unit has a thermal protection switch. The pump automatically stops if its internal temperature becomes too high and restarts after cooling, ensuring stable and safe system operation;
