CRVPRO BROCHURE

Product catalog summary

Introduction
The document introduces the CRVpro series of two-stage rotary vane vacuum pumps by Welch Vacuum, highlighting their durability, performance, and user-friendly design.

Key Features

Large Oil Capacity: Dilutes chemical vapors, minimizing oil breakdown and chemical attacks.
Cool Running: Enhanced airflow reduces operating temperature by 10°C, decreasing chemical activity and oil consumption.
Internal Surface Protection: PTFE and black oxide coatings slow corrosion and extend service intervals.
Low Noise Level: Designed for quiet operation.
Forced Oil Lubrication: Ensures fresh oil circulation, equilibrates temperature, and prolongs mechanical life.
Anti-Suck Back Valve: Prevents oil backflow during power failures.
Gas Ballast with Inert Gas Option: Minimizes chemical entrainment and protects against condensable liquids.
Certifications: cUL and CE certified for safety compliance.
Dual Voltage Motor: Switchable between 115V and 240V for global use.
Labyrinth Exhaust Baffling System: Reduces oil mist emission and noise (excluding CRVpro2).

Applications
The CRVpro series is suitable for various applications, including Schlenk lines, freeze dryers, vacuum ovens, glove boxes, and vacuum concentrators.

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. COOL RUNNING INTERNAL SURFACE PROTECTION Enhanced air flow allows the pump to run 10°C cooler than standard rotary vane pumps. The lower temperature leads to reduced chemical activity within the pump and slows down rates of oil consumption. Inside surface of the oil case has a PTFE coating and the outer surface of the pumping module has a black oxide coating. Both coatings act to slow metal corrosion and, when coupled with...

MASS SPECTROMETER PERFORMANCE NEW CRVpro GAS BALLAST SYSTEM Pump It's important to use the gas ballast function when pumping condensable vapours to ensure that they don't condense inside of the pump and cause oil degradation. As well as having a standard gas ballast valve for operation with atmospheric air, all CRVpro now come with the option to use dry inert gas for more efficient gas ballast performance. Use adapter kit to facilitate inert gas connection. Port enables use of dry inert gas for gas ballast DESCRIPTION ** CRVpro 2,4,6,8 are switch selectable between 220-240 V / 50 Hz; 230 V /...
