Description

Welch CRV Pro2 Model 3021-01 direct drive Rotary Vane Vacuum Pump. One advantage of the CRV Pro Vacuum pump is that has an much more increased reliability and longer service life vs other high performance, heavy duty vacuum pumps. The reason this rotary vane vacuum pump can achieve much higher robustness and reliability is because of three main point. First, this vacuum pump will run 10 Degrees Celsius cooler than other comparable pumps which means that the corrosion and wear and tear is slowed down. Second, this vacuum pump has 40% larger oil capacity than comparable vacuum pump, this larger oil capacity will further dilute any corrosive constituents inside the vacuum pump. Third, this vacuum pump has a chemical resistant coating in the oil case and pump module which means that all non-moving parts are protected from corrosion. Furthermore, the CRV Pro Rotary Vane Vacuum Pump consumes up to 36% less oil than other comparable vacuum pumps – this decreases the service and maintenance requirements of this vacuum pump.

The CRVPro Vacuum Pump includes all feature you need from a direct drive rotary vane vacuum pump such as Quick Flange Intake and Exhaust, Fastening Holes, Gas Ballast, Force Oil Lubrication, Anti-Suckback valve, and thermal overload protection

Common Applications include but are not limited to: degassing, vacuum ovens, vacuum concentrations, vacuum leak testing, altitude simulation, freeze drying, electronic equipment testing, and other vacuum applications. Please note that Direct drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other applications requiring sustained operation above 30 torr. Contact us to discuss your vacuum applications.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.
