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.

Pressure Decay Leak Testing Systems
Pressure Decay Leak Testing Systems are instruments that detect and quantify a leak by measuring the pressure drop over specified amount of time. Any specimen that is inflated will stay inflated if it is leak tight. On the other hand, of a leak exists in the inflated specimen, air will escape through the orifice and decrease the pressure inside the specimen. The higher the pressure drop, the high the leak.
Digital Vacuum Gauge Instruments
A Digital Vacuum Gauge is an instrument which precisely measures a vacuum level inside a vacuum chamber. Unlike a rough dial vacuum gauge, which shows only where the vacuum chamber is roughly with an error of up to 3% (a high as 1 inHg) a digital vacuum gauge will show vacuum levels up to 3 significant figure in Torr and millitorr – this makes the digital vacuum gauge ten thousand times more accurate than the dial vacuum gauge.
Our Work: Electronic Component Testing of Satellites at High Altitudes
Electronic Components of Satellites behave differently in outer space as compared to how these behave at sea level. How do you know that your satellite will survive outer space? How do you confirm that your circuit boards will function properly at higher altitudes? There is only one way to find out, and that is to test and validate your design.

How do you know that you have a good part during your leak test? In order to understand your leak test, you must first understand the Test Decay Curve and what it tells you about your test specimen. There is a certain way that a test specimen behaves during the leak test.
