Welch CRVpro4 Rotary Vane Vacuum Pump 2.8 CFM 115V, Low Noise, Chemical-Resistant, Reliable Performance

The Welch CRVpro4 Rotary Vane Vacuum Pump is a versatile and high-performance vacuum pump ideal for various applications. This direct drive vacuum pump series is engineered to offer increased reliability and longer service intervals compared to other direct drive rotary vane vacuum pumps. The CRVpro family stands out due to its innovative design and superior functionality, making it a top choice for professionals requiring high-quality vacuum solutions.

One of the standout features of the CRVpro4 is its impressive flow rate of 2.8 CFM (79 l/min). This efficient flow rate allows for effective vacuum creation, making it suitable for applications such as freeze drying, degassing, vacuum ovens, and concentrators. The pump is designed to handle the demands of these applications with ease, providing consistent performance.

Moreover, the CRVpro4 incorporates a large oil capacity, which significantly minimizes oil breakdown rates. This means less frequent oil changes and reduced downtime for maintenance, contributing to overall efficiency. Additionally, the chemical-resistant coating applied to both the oil case and pump module protects non-moving parts, ensuring longevity and reliability even in demanding environments.

Noise level is often a concern in laboratory settings, and the CRVpro4 addresses this issue effectively. With a noise level of up to ≤50 dB (A), this pump operates quietly, allowing for undisturbed work conditions. This feature is especially important where concentration and focus are crucial, making the CRVpro4 an excellent choice for laboratory and industrial use.

The CRVpro4 is wired for North American 115V, 60 Hz operation and comes complete with a North American line cord, a vacuum inlet hose barb designed for gum rubber hoses ranging from 5/8′ to 3/4′ ID, along with a charge of oil. This comprehensive package ensures that you have everything you need to get started right out of the box.

For users requiring a 230V option, the CRVpro2-01 variant is available, featuring a 230V North American line cord, UK cord, and Skuko cord, also including a charge of oil. This flexibility in voltage options makes the CRVpro series suitable for a wide range of international applications.

While the CRVpro4 excels in numerous applications, it is essential to note that direct drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other tasks that necessitate sustained operation above 30 torr. Be sure to consider your specific needs when selecting the right pump for your application.

In conclusion, the Welch CRVpro4 Rotary Vane Vacuum Pump is an excellent investment for those seeking a reliable, efficient, and quiet vacuum solution. With its robust features and advanced design, it stands out as a leader in the marketplace, ready to meet the demands of modern laboratories and industrial environments.
