Description

Welch CRV Pro 4 Model 3047-01 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.

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Belt Drive Rotary Vane Vacuum Pumps
A Belt Drive Rotary Vane Pump is almost identical to a Direct Drive Rotary Vane Pump. The only difference between the two is that the belt drive Rotary Vane Vacuum Pump is driven by a belt. There are several advantages why a belt drive vacuum pump would be preferable. One of these reasons is that the belt drive Rotary Vane Vacuum Pump runs at a slower RPM therefore the temperature created is lower, the wear and tear is less, and the overall lifetime of the pump is longer. The disadvantages are a lower CFM and performance.
Our Work: Bubble Leak Testing System with a Dry off Sink used for Leak Testing Large Bags
How do you leak test Large Food Bags? This is the same question a Large Food and Beverage Processor had asked themselves because they had need for a bubble leak testing system which could be used to detect presence of leaks in their large bags. Their requirements were to test several sized bags with the largest bag being 24 inches Wide by 12 inch Deep by 9 inches High. In addition to the bubble leak testing system, they also needed a way to dry the bags after the test.
