Explosion-proof rotary vane vacuum pump
Ensure safety and efficiency in flammable environments with this explosion-proof vacuum pump, designed for critical gas removal and pressure reduction in demanding petrochemical and chemical processes.
Generates Vacuum and Reduces Pressure Safely
The Welch CRVPro Rotary Vane Vacuum Pump, equipped with an explosion-proof motor, is designed specifically for petrochemical, chemical, and oil extraction industries. Its two-stage direct-driven design ensures reliable vacuum generation, essential for evacuating flammable and volatile gases. The pump offers free air displacement capacities from 2.8 cfm to 12.8 cfm, achieving ultimate pressures as low as 2×10⁻³ torr. This capability makes it ideal for applications involving ethylene, benzene, and solvent-based paints. Engineered for robust performance, it features a built-in oil filtration system and a larger oil chamber to minimize risk of chemical attacks, promoting extended operational intervals. The CRVPro series is cUL listed and rated for Class I, Groups C&D, and Class II, Groups F&G, ensuring compliance in explosive environments. Its manual or continuous operation, paired with a specialized coating on the pump module, provides resistance against corrosive vapors, integrating seamlessly into safety and environmental control measures within processing lines.
