Laboratory vacuum pump CRVpro 6

vanerotary vanebuilt-in

Overview
The CRVpro 6 is a two-stage rotary vane vacuum pump engineered for low maintenance and consistent performance. It incorporates a gas ballast valve, forced oil lubrication, anti-suckback mechanism and thermal overload protection. Designed as a direct-drive unit, it is suitable for laboratory and light industrial vacuum service.

Key Benefits

• Consumes up to 36% less oil than comparable pumps
• Operates up to 10°C cooler than comparable pumps, reducing corrosion risk
• 40% larger oil capacity than comparable pumps, helping to dilute aggressive chemicals
• Chemical-resistant coating in the oil case and pump module to protect non-moving parts

Typical Applications

• Freeze drying (lyophilization)
• Vacuum ovens
• Schlenk lines
• Backing pumps for turbomolecular pumps
• Degassing
• Vessel/chamber evacuation

Performance Summary

• Max pumping speed: 6 m3/h (100 l/min)
• Ultimate pressure (typical): 2x10-3 mbar

Notes

• Direct-drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other applications requiring sustained operation above 30 torr.
