Welch Gardner Denver CRVpro 2 Two-Stage Rotary Vane Vacuum Pump - NEW
The robust vacuum pump CRVpro 2 belongs to the new high-performance two-stage rotary vane pumps generation of Welch. The pump impresses with its long service life, absolute reliability and its low maintenance requirements.
This has been enabled thanks to 3 major innovations:
- Its low running temperature, which slows down potential corrosion processes and reduces the oil consumption.
- Its large oil reservoir ensures a low chemical concentration, which contributes to the prolongation of the oil exchange intervals.
- Its special inside coating increases the chemical resistance of the pump.
Scope of delivery: Pump with motor, 3 line cords (EU/UK/US), 2 liters of oil, centering ring with dirt trap, centering ring, 2 clamping rings.
