Laboratory vacuum pump CRVpro 2

rotary vanemulti-stagelubricated

Overview
The CRVpro 2 is a two-stage rotary vane vacuum pump designed for laboratory and light industrial evacuation tasks. It features gas ballast, forced oil lubrication, an anti-suckback mechanism and thermal overload protection to support intermittent vacuum operations and protect the pump during normal use.

Applications

• Freeze drying (lyophilization)
• Vacuum ovens
• Schlenk lines and glovebox backing
• Backing turbo-molecular pumps
• Degassing liquids and resins
• Vessel and chamber evacuation

Key features

• Two-stage rotary vane design for improved ultimate pressure
• Gas ballast port for humidity and vapor handling
• Forced oil lubrication and larger oil capacity (450 ml) for chemical dilution
• Chemical-resistant coating on oil case and pump module for non-moving part protection
• Low noise level (≤50 dB(A) at 50 Hz)
• Max pumping speed: 2.5 m³/h (42 l/min); ultimate pressure: 3×10⁻4 mbar

Notes for users

• Direct-drive rotary vane pumps are not recommended for continuous operation above ~30 torr or for filtration/aspiration processes that draw particulate matter.
• Use appropriate vacuum tubing and KF adapters to maintain performance; follow oil-change intervals and safety procedures for pumped vapors.
