CRVpro 8 115V 1Ph Direct Drive Rotary Vane Vacuum Pump w/ US Plug & NW16 5/8" Hose Barb
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.
Includes
- Pump with motor
- Line cord (US-plug; 115V Nema-5)
- Manual (english)
- 1 quart (0.94 liter) vacuum oil bottle
- Centering ring with dirt trap
- Centering ring
- Protection cap
- Plastic ring
- Clamping ring (DN16KF)
- Hose barb adapter
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.
The CRVpro series vacuum pumps are oil-sealed, two-stage rotary vane vacuum pumps. The drive motor is directly flange-mounted onto the motor cover of the pump holder and the pump shaft and the motor shaft are connected to each other by an elastic coupling. The bearings of the interior pump body are force-fed lubricated sliding bearings.
The range of application of our oil-sealed rotary vane vacuum pumps encompasses the entire field of vacuum technology, both for use in the laboratory and in industry. The task is to create end pressures (partial) down to around 10-3mbar:
- as a single vacuum pump
- as a fore-vacuum pump for oil diffusion pumps or as turbomolecular pumps
The rotary vane vacuum pump can evacuate containers or vacuum installations up into the high vacuum range.
