CRVpro – Welch's innovation in the field of two-stage rotary vane vacuum pumps

Available in three different versions – CRVpro 4, 6 and 8 – the products provide highest reliability for stable operations as well as a long product lifespan.

Due to its low noise level the robust vacuum pumps series ensures undisturbed working. Furthermore the cool running CRVpro pumps guarantee less oil consumption and a slowed down corrosion. By diluting chemical vapors with a larger oil chamber there is also a reduced risk of chemical attacks and oil breakdowns.

Convincing with a modern and compact design, the CRVpro vacuum pump series fits different performance requirements perfectly and is for example applicable to freeze dryers, vacuum concentrators, schlenk lines, glove boxes, industrial applications, HVAC and vacuum ovens.
