Features
Chemical Duty Diaphragm Pump
- Chemical resistant against solvents, acidic and basic vapors
- Constructed with corrosion resistant PTFE and perfluoro plastic materials
- Oil-free for low maintenance operation
- Comes standard with fine tune adjustable knob
- Wired for 110V 60HZ
- Free air displacement @60Hz: 0.9 cfm (25 L/min)
- Ultimate pressure: 2 Torr (2.7 mbar)
The 2032 sits at the top of the DryFast Ultra range for depth of vacuum: at 2 Torr it can handle high-boiling solvents such as DMF, which shallower diaphragm pumps cannot pull off. Welch rates it to strip 2-4 ml/min of DMF at 35 C when used with a dry ice condenser, so heat-sensitive extracts stay cool.
Every wetted part is chemical-resistant: solid PTFE heads, PTFE diaphragms, Kalrez valves and fluorinated plastics. Advanced Vapor Management (AVM) gives you precise control during distillation of organic solvents, and the adjustment knob sits front and centre.
Because it runs dry, no cold trap is needed to protect pump oil, and maintenance is limited to occasional diaphragm and valve service. It is certified for rotary evaporation, concentrators, vacuum ovens, filtration and degassing.
