Laboratory vacuum pump CRVpro 48

rotary vanelubricated

Overview

• CRVpro family includes direct-drive rotary vane vacuum pumps with standard features: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection.
• Consumes up to 36% less oil than comparable pumps.
• Operates approximately 10°C cooler than comparable pumps, reducing internal corrosion rates.
• 40% larger oil capacity than comparable pumps to help dilute aggressive condensable vapors.
• Chemical-resistant coating on the oil case and pump module to protect non-moving parts.
• Max pumping speed: 55.7 m3/h (≈928 l/min @ 50 Hz)
• Ultimate pressure: 3 x 10^-3 to 3 x 10^-4 mbar depending on conditions (see Technical data).

Applications

• Freeze drying (lyophilization)
• Vacuum ovens
• Schlenk lines
• Backing (roughing) pump for turbomolecular pumps
• Degassing
• Vessel / chamber evacuation
• Not recommended for filtration, aspiration, drying electrophoresis gels, or continuous operation above 30 torr.
