Welch Explosion Proof CRVpro4 Direct Drive Rotary Vane Vacuum Pump

The new CRVpro family of direct drive vacuum pumps offers increased reliability and longer service interval vs. other direct drive rotary vane vacuum pumps. The CRVpro family consumes up to 36% less oil than comparable pumps. Three features drive these benefits: 

• Runs 10°C cooler than comparable pumps. Slows corrosion. 
• Has a 40% larger oil capacity than comparable pumps. Dilutes aggressive chemicals. 
• Has a chemical resistant coating in the oil case and pump module. Protects non-moving parts. 

The CRVpro family includes all the features you'd expect in a direct drive rotary vane pump: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection. 

Suitable applications include freeze drying, degassing, vacuum ovens and concentrators.

 

3046E-01 comes with an explosion proof motor. Conduit wiring installation required. No cord, plug, or switch provided. 

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