3042-00 - Rotary vane pump CRVpro 4

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
