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. 
Free Air Displacement @ 60 Hz, cfm (L/min) 12.8 (363)
Free Air Displacement @ 50 Hz, m³/hr (L/min) 18.3 (305)
Ultimate Pressure, torr (mbar) 2x10⁻­³ (3x10⁻³)
Noise Level, dBA 55
Motor Speed, RPM, @60Hz, @50Hz 1750 (1450)
Motor Power, HP (kW) 1.1 (0.85)
Oil Capacity, mL 2400
Connection Flanges NW25
Inlet Hose Connection* 5/8" to 3/4"
Weight, lbs (kg) 81.6 (37)
Dimensions, LxWxH, in (mm) 22.4x8.1x11.4 (569x206x289)

 

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.

    CRV Pro16 catalog# 3161-01 is wired for North American 115V, 60Hz operation. Includes North American line cord, vacuum inlet hose barb suitable for gum rubber hose from 5/8" to 3/4" ID, and a charge of oil.

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