Welch CRVpro Direct Drive Rotary Vane Vacuum Pump

Welch CRVpro Direct Drive Rotary Vane Vacuum Pump

CRVpro provides reliability for stable operation and long product lifespan. Customers benefit from a reduced risk of chemical attacks and oil breakdown by diluting aggressive chemicals with a larger oil chamber. Its cool running characteristic also slows down any corrosion process. Additionally a chemical resistant coating protects the stationary components. Furthermore the CRVpro enables extended oil change intervals for less maintenance costs. Less oil consumption is a result of the cool running operation and the extended usability of oil based on a high dilution effect because of a larger oil chamber. Moreover, the low weight, flexible handle and compact design of the pump makes the rotary vane pump a portable and flexible partner in laboratories and industrial applications. With its low sound level the CRVpro series ensures that users work in a calm surrounding.
