The Welch Oil-Free High Capacity Diaphragm Pumps use dry, oil-free membrane (diaphragm) technology to deliver faster pumping dynamics that support filtration, evaporation, drying, degassing, impregnation, and other rough vacuum applications. The superior vapor tolerance and gas ballast valve for handling heavy vapor loads.

or high vapor flow in larger scale laboratory vacuum applications
Used where vacuum pressure requirements are to the low Torr range(~1.5 to 56 TORR) and low maintenance is a priority
All internal parts in contact with gases are made of chemically resistant fluoroplastics
Superior vapor tolerance and gas ballast valve for handling heavy vapor loads. The gas ballast valve preserves the pump performance under heavy vapor load by leaking air into second stage to inhibit condensation
Rotary evaporation is a laboratory technique commonly used for a variety of applications. These uses include: removing (distilling or “stripping”) a solvent or solvents from a sample, concentrating a solution, recycling solvents, or synthesizing chemicals.
