Welch Gardner Denver CRVpro 4 Two-Stage Rotary Vane Vacuum Pump - NEW

The robust vacuum pump CRVpro 4 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.
