Rotary Vane Pump & System
CRV PRO 2

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.

Benefits:

• Reduced risk of chemical attacks and oil breakdown by diluting chemical vapors with a larger oil chamber
• Slowing down corrosion by cool running operation
• Provides a measure of protection from sublimed chemical vapors with coating on pump module and oil case
• Less oil consumption by cool running operation
• Extended usability of oil due to high dilution effect by a larger oil chamber
