CRVpro Direct Drive Rotary Vane Vacuum Pumps
Manufacturer: Welch Ilmvac
Description
The Welch CRVpro Direct Drive Rotary Vane Vacuum Pumps offer increased dependability and overall satisfaction for your lab applications. CRVpro vacuum pumps are two-stage direct-driven vacuum pumps. CRVpro 2, 4, 5, 6, 8 are switch selectable between 115V, 60Hz, and 230V, 50/60Hz operation; CRVpro 16, 24, and 30 models are not switch selectable; they are dedicated to either 115V, 60Hz or 230V, 50/60Hz. Each motor includes overload protection.
Enhanced airflow 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 foreline traps, extend service interval. Chemical vapors that sublime from the foreline cold trap into the pump oil are more diluted due to the larger oil capacity. This minimizes the rates of oil breakdown and reduce chemical attacks within the pump.
Features:
- Exceptionally quiet for undisturbed work
- Force Oil Lubrication ensures moving parts are bathed in fresh oil - Equilibrates temperature, minimizes oil breakdown, and prolongs mechanical life
- Anti Suck Back Valve prevents oil from being sucked into application in the event of a power failure
- Gas Ballast with Inert Gas Option minimizes entrained chemicals in pump oil - Protects pump from condensable liquids from application such as water, acetyl nitrile, etc.
- cUL / CE Certification compliance with local regulations and safety directives for safety operation
- Modern and compact design to fit different applications and performance requirements
- Dual voltage motors meet IP54 standard
Please Note: Always use a certified electrician for proper installation of pumps with 3 phase or explosion proof pumps motors. Conduit wiring required. (No cord, plug, or switch included.) 3 phase, CE, cUL on motors only. 60Hz Explosion proof motor rating is Class 1, Groups C&D; Class 2, Groups F&G. 50 Hz Explosion Proof motor rating is class I, Group D; Class 2, Groups F&G.
