The Welch CRVpro2 Rotary Vane Vacuum Pump, 1.5 CFM, 230V (79206-03; Welch 3022-01) is a two-stage, direct-drive vacuum pump providing a free air capacity of 1.5 CFM (42 L/min). Designed for 230 VAC, 50/60 Hz operation, it combines a cooler-running oil-sealed design with gas ballast, forced oil lubrication, anti-suckback protection and thermal overload protection for laboratory vacuum applications.
Key Features
- 1.5 CFM free air capacity, equivalent to 42 L/min on the verified Cole-Parmer configuration
- Two-stage direct-drive rotary vane design, providing oil-sealed vacuum performance for laboratory applications
- Deep vacuum capability, with a specified maximum vacuum of 0.0705 Torr
- Gas ballast operation, with a maximum vacuum of 9 × 10^-2 mbar (7 × 10^-2 Torr) when the ballast is used
- Lower ultimate pressure without gas ballast, rated at 3 × 10^-3 mbar (2 × 10^-3 Torr)
- Cooler-running airflow design, operating 10°C cooler than comparable pumps and consuming up to 36% less oil
- Low operating noise, rated at ≤50 dB(A)
- IP54 enclosure protection, providing a defined level of enclosure protection
- 450 mL oil capacity, supporting the pump's oil-sealed rotary vane operation
- NW 16 flange outlet, providing the specified vacuum connection format
- PTFE wetted parts, as specified for this exact Cole-Parmer item
- 230 VAC, 50/60 Hz operation, matching the electrical configuration of this variant
- Integrated operating safeguards, including anti-suckback and thermal overload protection
- Supplied operating components, including Directorr Premium vacuum pump oil, centering rings, clamping rings and a power cord
Benefits
- Reduces oil consumption through a cooler-running design that limits unnecessary oil degradation during operation.
- Helps protect non-moving pump components through a chemical-resistant coating in the oil case and pump module.
- Reduces condensable vapours entering the pump oil by allowing the gas ballast to use outside air or dry inert gas.
- Supports quieter laboratory operation with a specified noise level of no more than 50 dB(A).
- Supports applications including freeze drying, degassing, vacuum ovens and concentrators.
- Helps protect the vacuum system during operation through anti-suckback and thermal overload features.
