Built for Demanding Applications
If you're working with sensitive biotech samples, freeze drying processes, or high-precision vacuum environments, pump reliability isn't optional. Welch’s CRVpro series is engineered for consistent performance under demanding conditions—whether you're running vacuum ovens, glove boxes, schlenk lines, or backing turbo molecular pumps.
These two-stage, oil-sealed rotary vane pumps deliver high pumping speeds down to 0.0015 torr. With nine models ranging from 1.8 to 52.5 cfm, CRVpro covers a wide spectrum of lab and industrial needs. Each unit is compact, quiet, and built with protective internal coatings to extend service life. Models prepared with PFPE are available for oxygen service.
