Alcatel 2004A Dual Stage Rotary Vane Vacuum Pump

The Alcatel 2004A Dual Stage Rotary Vane Vacuum Pump is a two-stage, oil-sealed rotary vane pump designed for medium vacuum work in laboratory and industrial settings. It provides a nominal pumping speed of about 3.2 CFM and can achieve deep vacuum levels on the order of 1×10^-4 Torr, enabling use in degassing, drying, simple distillation, and sample preparation where steady vacuum is needed. As part of the Adixen/Alcatel Pascal/A-series family, the 2004A is commonly configured for both single-phase and three-phase service, with voltages such as 115/230 V for single-phase and 220/380 V for three-phase installations, and many units are listed around 1/2 HP. The pump's oil-sealed mechanism supports continuous operation while requiring periodic maintenance and oil changes to sustain performance. Its design emphasizes serviceability, with documentation noting easy dismantling and reassembly for field servicing. Overall, the 2004A provides a robust, compact solution for mid-to-high vacuum tasks in research, chemistry, and other applications that rely on reliable, repeatable vacuum generation.
