Product information
The pump is equipped with two double-lobe or multi-lobe rotors rotating synchronously in opposite directions. A certain gap is maintained between the rotors and between the rotors and the inner wall of the pump casing. It belongs to a rotary variable displacement vacuum pump. Mechanical booster pumps are this form of vacuum pumps.
application recommendation
The following is a detailed analysis of the main application areas and recommended scenarios of Roots vacuum pumps: 1. Industrial applications in the chemical industry Vacuum distillation, dehydration, impregnation and other processes Treatment of viscous/corrosive media (such as petroleum, asphalt) Equipped with insulation layers to adapt to high-temperature fluids Electronic semiconductors Vacuum coating pre-pumping Semiconductor manufacturing High vacuum environment (Extreme vacuum up to 0.1Pa) Clean pumping of LCD/LED production line Power equipment Transformer vacuum drying Capacitor dipping 2. Medical equipment supporting for medical field applications Medical suction system (operating room/ambulance) Central oxygen supply system Negative pressure maintenance Rapid suction of dental surgical fluids Pharmaceutical process Drug raw material transportation Online cleaning in compliance with GMP standards 3. Environmental protection and special fields water treatment systems Sludge treatment Groundwater table reduction Scientific research experiments Space simulation experiments Material preparation High vacuum environment 4. Recommended combined systems High vacuum units Roots pump + screw pump (Extreme vacuum 0.1Pa) Roots pump + water ring pump (processing vapor-containing media) Energy-saving configuration Two-stage Roots pump system (energy consumption reduced by 12%) Air-cooled Roots pump (direct discharge atmospheric pressure difference 8.7×10 Pa) Note: Specific selection needs to match application requirements based on flow rate (30- 20,000 L/s), pressure range (0.05-0.2MPa) and other parameters.
