    New CRVpro series of general purpose vacuum pumps from Welch have been added. Discover the evolution of two-stage rotary vane vacuum pumps. Built to last. Born to perform. And designed to simplify your work. Meet the robust vacuum pump series – CRVpro.

    Features and 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.
    - Exceptionally quiet for undisturbed work.
    - Ensures moving parts are bathed in fresh oil. Equilibrates temperature, minimizes oil breakdown, and prolongs mechanical life.\
    - Prevents oil from being sucked into application in the event of a power failure.
    - Minimizes entrained chemicals in pump oil. Protects pump from condensable liquids from application such as water, acetyl nitrile, etc.
    - Compliance with local regulations and safety directives for safety operation.
    - Modern and compact design to fit different applications and performance requirements.
    - IP44 Motors are switchable from 115V to 240V for global use. Each pump includes power cord suitable for country of use.
