Vacuum Pumps for laboratories
The new CRVpro family of direct drive vacuum pumps offers increased reliability and longer service interval vs. other direct drive rotary vane vacuum pumps. The CRVpro family consumes up to 36% less oil than comparable pumps. Three features drive these benefits:
Runs 10°C cooler than comparable pumps. Slows corrosion.
Has a 40% larger oil capacity than comparable pumps. Dilutes aggressive chemicals.
Has a chemical resistant coating in the oil case and pump module. Protects non-moving parts.
The CRVpro family from Welch includes all the features you'd expect in a direct drive rotary vane pump: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection.
CRVpro2 vacuum pumps can be used for freeze drying, vacuum ovens, schlenk lines, backing turbo molecular pumps, degassing, vessel/chamber evacuation.
The LabTech vacuum pumps are totally oil free, featuring an advanced design, low noise level, high efficiency and long lifespan. LabTech pumps are specially designed for laboratory operations to meet the highest expectations for precision, reliability and ease of use. They can be used in a multitude of applications, such as vacuum filtration, degassing, impregnation, drying chambers, rotary evaporation, distillation, gel dryers, gas analytical systems and roughing of a wide-range of turbo molecular pumps.
In spite our membrane pumps have been created as ancillary items for our rotary evaporators they are pretty successful even in case of other applications such as vacuum filtration, degassing, impregnation, drying, rotary evaporation, distillation and so on, having being conceived for laboratory operations to meet the highest expectations for precision, reliability and ease of use. Compact and light they can be easily moved according to the user requirements. 3 models are available featuring pumping speeds from 18 to 50 L/min.
