Greetings! This is Green Pneumatic Vacuum to Zero (VTZ), a company specializing in vacuum pumps.

Nowadays, a stable vacuum environment is essential in laboratories, research institutes, and various industrial settings. Vacuum is used in diverse applications such as analyzing samples, removing moisture, and accelerating process speeds. However, when trying to build a vacuum system, the question “Which pump should I use?” often arises.

In such cases, the reliable choice is the Edwards RV Series Oil Rotary Vane Pump. This series is a proven model, balancing both stability and performance, with hundreds of thousands of units sold worldwide. It is consistently used as the primary vacuum source in many laboratories.

🔍 2. What are the key features of the RV Series?

The RV Series is a compact yet robust oil-sealed, dual-stage rotary vane pump.
Its biggest advantage is supporting ‘two modes with one unit’.
You can switch between High Vacuum Mode and High Throughput Mode with a single switch.
The two-stage gas ballast function ensures stable performance even in environments with high moisture or vapor content.
Thanks to its low-noise design (around 48 dB), it operates quietly even in a laboratory setting.
Maintenance is simple with well-placed oil level sight glass and oil drain port.
In short, it offers top-tier performance and convenience despite its small size. This is why it remains a consistently popular choice across various fields.

✅ 3. Key Specifications of the RV Series

Let’s briefly summarize the performance of this product line:
• Pumping Speed: Approx.  3 ~ 12 m³/h (Varies by model)
• Ultimate Vacuum Pressure: Approx.  2 × 10⁻³ mbar
• Water/Vapor Handling Capacity: Up to 290 g/hr
• Noise Level: Approx. 48 dB(A)
• Power Options: Supports both Single-Phase and Three-Phase
Just looking at the specifications, any thought that “a small pump might have weak performance” is completely dispelled. In reality, it delivers stability comparable to high-end equipment in various environments.

​

💼 4. Where is it best used?

The RV Series has a very high utility, from laboratories to industrial processes.
For example, it is suitable for:
• Use as the primary vacuum source for analytical instruments (GC-MS, LC-MS, etc.)
• Laboratory processes such as freeze-drying, filtering, and sample concentration
• Backing pump for turbopumps
• Stable operation in high-moisture processes or vapor evacuation environments
I have personally used a similar pump in a lab, and its reliability was truly reassuring. The pump consistently delivered its performance even after handling high-moisture samples, making management much easier.

💡 5. Maintenance is Simple

Another attractive point of the RV Series is the ease of management.
• The oil level is easy to check.
• Cleaning and replacement are simple thanks to the conveniently located bottom drain port for oil discharge.
• The two-stage gas ballast and mode selection switch allow for flexible adaptation to different situations.
• The low-noise design permits use without disruption in sensitive research environments.
These features make equipment management much easier and help reduce maintenance costs. When choosing a pump, maintenance convenience is just as important as mere performance.

🛠 6. Tips to Know Before Purchase

Before introducing the RV Series, be sure to check the following points:
• Calculate your vacuum requirements in advance. The model selection depends on how low a pressure is needed and how fast the pump-down is required.
• Always check the power specifications. Stable operation requires matching the single/three-phase, voltage, and frequency.
• Understanding the gas ballast function significantly boosts moisture handling efficiency.
• Regular oil management is mandatory. The condition of the oil directly affects pump performance.
• Verify the noise conditions. The RV Series is quiet, averaging 48dB, but this can vary depending on the environment.
Carefully checking these items will greatly reduce post-installation issues.
