Laboratory vacuum pump CRVpro 16

rotary vanelubricatedmulti-stage

Overview
The CRVpro family delivers high-performance two-stage rotary vane pumping with features expected in direct drive rotary vane pumps: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection.

Key features

• Consumes up to 36% less oil than comparable pumps.
• Runs ~10°C cooler than comparable pumps, reducing corrosion.
• 40% larger oil capacity than comparable pumps to dilute aggressive chemicals.
• Chemical-resistant coating in the oil case and pump module to protect non-moving parts.
• Includes gas ballast, forced oil lubrication, anti-suckback and thermal overload protection.
• Max pumping speed (nominal): 18.3 m3/h (305 l/min).
• Ultimate pressure (typical): see technical data table below.

Applications

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

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