Overview
The Welch DryFast 2014 is a single-stage, oil-free PTFE diaphragm pump for chemical duty. It moves 1.2 cfm (35 L/min) of free air at 60 Hz and reaches an ultimate pressure of 40 Torr (53 mbar).
The heads are PTFE, the valves are perfluoroelastomer and the wetted surfaces are fluorinated plastic, so it stands up to solvent, acidic and basic vapours. Welch rates it for evaporating solvents with atmospheric boiling points up to 80 °C. A fine-tune knob on the pump lets you adjust the vacuum.
