Welch CRVpro4 Model 3041-01 Rotary Vane Vacuum Pump 2.8 CFM, Ultimate Pressure 2x10⁻³ mbar
Product Description
The Welch CRVpro4 (Model 3041-01) is a high-performance, two-stage rotary vane vacuum pump engineered for laboratory and bioprocessing applications requiring reliable vacuum generation. Key technical specifications include:
- Free air displacement of 2.8 CFM (78 L/min) at 60 Hz, suitable for continuous vacuum processes in molecular diagnostics and synthetic biology workflows.
- Ultimate vacuum pressure capability of 2x10⁻³ mbar (1.5x10⁻³ Torr), supporting sensitive fluorescence analysis and live-cell imaging systems.
- Energy-efficient design consuming up to 36% less oil than comparable pumps while running 10°C cooler to minimize corrosion and prolong service life.
- Chemical-resistant coating and a 40% larger oil capacity enable extended durability and effective dilution of aggressive chemicals common in biomanufacturing and gene editing environments.
- Versatile voltage compatibility with options for 115V/60Hz and 208-230/460V 50/60Hz configurations, allowing integration into diverse laboratory power setups.
- Includes essential operational accessories: Oil Mist Separator (P/N 320015) and Vacuum Inlet Separator (P/N 320016), critical for maintaining clean vacuum lines in clinical diagnostics and biotechnology research.
- Constructed in the United States, the pump weighs 47 lbs (actual) and measures 7" x 19" x 11", optimizing bench space efficiency in biomedical engineering labs.
Widely adopted in biopharmaceutical production pipelines and molecular cloning workflows, the CRVpro4 rotary vane vacuum pump offers robust, low-maintenance vacuum performance. Its ability to maintain low ultimate pressures with high chemical resistance makes it essential for advanced research fields including neuroscience, biotechnology, and molecular biology. The pump’s proven reliability and performance align with quality standards expected in clinical research and synthetic biology laboratories.
