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.
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
