2BV Water Ring Vacuum Pumps: Simple, Reliable, and Ready for Tough Jobs

1. What Makes the 2BV Series Special

1.1 Strong Performance with Gas and Steam

The 2BV water ring vacuum pumps are designed to handle gas and steam with ease. They can reach a vacuum level of up to 97%. And when transformer oil is used as the working liquid, the vacuum level can go even higher—up to 99%. This makes them a great replacement for old-style reciprocating vacuum pumps.

1.2 Built to Work Under Hard Conditions

When the pump runs near its limit vacuum for a long time, cavitation may happen. To prevent this, the 2BV series includes a cavitation protection port. This helps reduce noise and protects the pump from damage so it can keep running smoothly.

2. Where the 2BV Pumps Are Used

2.1 Industries That Count on 2BV Pumps

The 2BV pumps are widely used in many fields, such as:

Power industry – transformer vacuum pumping and drying.

Food and pharma – vacuum concentration, distillation, and drying.

Electronics and packaging – vacuum sealing and molding.

General manufacturing – vacuum lifting, conveying, and forming.

2.2 Handling Dangerous or Special Gases

The 2BV2-Ex and 2BV6 series are designed for explosive or flammable environments. Their performance is the same as standard 2BV models but with added safety features. This makes them ideal for chemical plants, gas treatment systems, and oil refineries.

2.3 For Corrosive or Clean Environments

Stainless steel versions of the 2BV pump can deal with stronger corrosive gases or liquids. They are also perfect for industries that require high cleanliness, such as food, medicine, and fine chemicals.

3. Smart Design That Saves Time and Space

3.1 Simple to Install

The close-coupled structure makes the pump compact and easy to fit into small spaces. It’s a plug-and-play design that reduces installation work.

3.2 Strong Parts for Long Life

The pump uses a John Crane mechanical seal, a high-strength aluminum bronze impeller, and top-quality bearings from NSK or NTN. These features help the pump work longer, resist wear, and handle tough conditions.

3.3 Safe Operation and Energy Use

A specially designed discharge port helps avoid over-pressure, improving working efficiency. When used as a compressor, the pump can handle pressure up to 0.26 MPa, but choosing the right motor is important because higher pressure means higher power use.

Final Thoughts

The 2BV series water ring vacuum pumps are simple to use, safe to operate, and suitable for a wide range of industries. Whether dealing with explosive gases, corrosive environments, or everyday vacuum tasks, the 2BV pumps deliver steady and reliable performance.
