Description
This used Welch MPC 301 E Diaphragm Vacuum Pump is a chemical-duty diaphragm (membrane) vacuum pump designed for laboratories and analytical use. It provides a clean, oil-free vacuum with excellent chemical resistance thanks to PTFE wetted materials.
This single-stage direct-drive pump delivers free air displacement in the range of 38–41 L/min, and an ultimate vacuum pressure under 75 mbar, making it suitable for applications like vacuum filtration, rotary evaporation, degassing, and solvent removal. The wetted parts are robust for handling aggressive vapors and solvents.
Compact, durable, and versatile, it’s ideal for labs needing a reliable chemical-resistant vacuum source without oil contamination.
