Welch® CRVpro™ Rotary Vane Vacuum Pumps
These two-stage rotary vane vacuum pumps are designed to simplify task and provides highest reliability for stable operation and long product lifespan.
- Low noise level
- Anti-suck back valve
- Forced oil lubrication
The motors of these pumps are dual voltage functional that is switchable from 115 to 240 V. Cool running operation of this pump provides less oil consumption and slowing down corrosion.
These provide a measure of protection from sublimed chemical vapors with coating on pump module and oil case. Ensures the extended usability of oil due to high dilution effect by a larger oil chamber.
CRVpro starter package includes CRVpro with oil mist separator AKD 16, 2-way ball valve, hose connector DN 16KF-10/8 mm, vacuum hose (1,5 m), oil change set.
CRVpro premium package includes CRVpro with digital vacuum gauge PIZA 111 cr-gold, oil mist separator AKD 16, 2-way ball valve, T-piece, hose connector DN16KF-10/8 mm, vacuum hose (2,5 m), oil change set.
: Supplied complete with Directorr™ Premium vacuum pump oil, centering rings, clamping rings and motor overload protection. Ready for use after oil filling.
