The 2BE1S series water ring vacuum pump is an advanced two-stage version of the single-acting 2BE1 series. It offers improved performance, especially in high vacuum applications. While the 2BE1 series has an ultimate pressure of 3300 Pa and is ideal for working pressures between 20 kPa and 100 kPa, its efficiency drops significantly when the inlet pressure falls below 20 kPa. The 2BE1S series addresses this by incorporating a two-stage compression process, ensuring stable pumping speed in high vacuum ranges and maintaining a high level of vacuum across a wide range of pumping rates. This model improves efficiency by 35–40% compared to single-stage pumps and reduces energy consumption.
Working Principle
The 2BE1S two-stage water ring vacuum pump operates similarly to the single-stage 2BE1 model. When the impeller rotates, it creates an eccentric water ring inside the casing. Water fills the spaces between the blades, and as the impeller rotates, the volume between the blades changes periodically, enabling the suction, compression, and discharge processes. In the two-stage system, gas from the first stage is drawn into the second stage for further compression before being discharged. This design enhances efficiency and performance at lower pressures.
Features
- Limit pressure up to 2 kPa
- Working pressure range: 5 kPa – 20 kPa
- Wide range of specifications: 200 – 7500 m³/h
- Available in various materials such as stainless steel, duplex steel, titanium, and Hastelloy
- Reliable locking mechanism for wheel fixation
- Mechanical seals at both ends with optional flushing programs
- Standard anti-cavitation device
- Energy-efficient and highly reliable
- Precision castings, high-standard bearings, and accessories
- Excellent design and structure, suitable for industries like chemical, food, pharmaceutical, textile, power, papermaking, and metallurgy
This pump is particularly effective when used in conjunction with a Roots vacuum pump, offering enhanced performance in vacuum drying, concentration, evaporation, distillation, dehydration, degassing, and filtration processes.
