The EvapoBean™ DP-F20 II Diaphragm Vacuum Pump is a two-stage, oil-free vacuum solution engineered for chemically aggressive laboratory environments. Featuring an all-PTFE gas-contact design, dry operation, and compact footprint, it delivers clean, reliable vacuum performance without oil mist, wastewater, or routine maintenance. Designed to replace traditional water circulation vacuum pumps, the DP-F20 II ensures stable operation for a wide range of laboratory vacuum applications.
• Two-Stage Oil-Free Vacuum Technology: Dry, oil-free and water-free operation eliminates contamination risks and reduces environmental impact.
• High Vacuum Performance: Ultimate vacuum of approximately 10-15 mbar (no-load) with maximum flow rate up to 20 L/min.
• Low Noise and Low Vibration: Direct-drive motor and low-stroke diaphragm design maintain noise levels below 70 dB.
• Integrated Overheat Protection: Automatic thermal protection shuts down the pump if internal temperature exceeds safe limits.
• Compact Benchtop Design: Small footprint and moderate weight (~9.4 kg) for easy integration into laboratory setups.
• Wide Application Range: Suitable for rotary evaporation, vacuum filtration, distillation, drying, concentration, degassing, and solid-phase extraction.
