Description

All Welch CRVpro high vacuum pumps rebuilt and sold through AVAC have been completely disassembled, cleaned, re-machined and carefully inspected for wear by our factory trained technicians. Units are assembled with new vanes, shaft seals, exhaust valves, gaskets, springs, oil pumps and bushings, prior to undergoing an extended performance test to meet or exceed OEM specifications. All pumps are then painted, detailed, and pass a final quality assurance inspection prior to shipping. A final test certificate is provided with each pump, which will be covered with a one-year warranty.

LOW NOISE LEVEL
Exceptionally quiet for undisturbed work.

FORCED 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
Minimizes entrained chemicals in pump oil. Protects pump from condensable liquids from application such as water, acetonitrile, etc.

cUL and CE CERTIFICATION
Compliance with local regulations and safety directives for safety operation.

SIZED TO FIT YOUR APPLICATION
Modern and compact design to fit different applications and performance requirements.

DUAL VOLTAGE MOTOR
IP44 Motors are switchable from 115V to 240V for global use. Each pump includes power cord suitable for country of use.

YOUR 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

Highest reliability for stable operation and long product lifespan

Extended oil change intervals for less maintenance costs
