Rotary Vane Vacuum Pump

Achieve optimal vacuum generation using rotary vane pumps for
both lab and industrial applications


A rotary vane vacuum pump uses rotating vanes to create and maintain essential vacuum conditions, forming the foundation of advanced vacuum technology, and driving scientific, research, and industrial advances. Welch's wide range includes both low and high-capacity models each designed for specific vacuum requirements, with pump speed ranges from 3 to 109 m³h and vacuum pressures up to 0.0004 mbar. Witness precision and innovation harmonize across industries, refining outcomes in laboratories, manufacturing, and beyond.
