Welch CRVpro 16 Direct Drive Pump - Catalog 3161-01
- 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.
