Discover the evolution of two-stage rotary vane vacuum pumps. They are built for durability, performance, and to simplify your work.
It includes all the standard features of a direct-drive rotary vane pump: gas ballast, forced oil lubrication, an anti-suckback mechanism, and thermal overload protection.
This pump consumes up to 36% less oil than comparable pumps and runs 10 °C cooler, which slows corrosion throughout the system.
It also offers a 40% larger oil capacity than comparable pumps, helping dilute aggressive chemicals and extend oil life. In addition, it features a chemical‑resistant coating in the oil case and pump module that protects non‑moving parts.
Reduces the risk of chemical attacks and oil degradation by diluting chemical vapors with a larger oil chamber
Slows down corrosion through cool-running operation
Provides additional protection against sublimed chemical vapors with coatings on the pump module and oil case
Reduces oil consumption through cool-running operation
Extends oil life thanks to a larger oil chamber that provides a high dilution effect
Low noise level
Exceptionally quiet operation ensures an undisturbed work environment.
Forced oil lubrication
Keeps all moving parts continuously bathed in fresh oil, equilibrates temperature, minimizes oil degradation, and extends mechanical life.
Anti-suck back valve
Prevents oil from being drawn back into the application in the event of a power failure.
Gas ballast with inert gas option
Minimizes entrained chemicals in the pump oil and protects the pump from condensable liquids, such as water or acetonitrile.
Certifications
cUL and CE certified to comply with local safety regulations and directives.
Sized to fit your application
Modern, compact design fits a variety of applications and performance requirements.
Dual voltage motor
IP54-rated dual voltage motors (CRVpro 2, 4, 6, 8) are switchable between 115 V and 240 V for global use (excluding 100 V and 200 V versions). Each pump includes a power cord suitable for the local country.
Labyrinth exhaust baffling system
Reduces oil mist emissions and lowers noise levels (not available on CRVpro 2).
