2BV liquid-ring vacuum pump operates on a liquid-ring principle, using water or other suitable liquids as the sealing medium to prevent contamination during operation while continuously extracting air, water vapor, and other gases with excellent adaptability to moisture and condensed vapor. The product is equipped with a water tank, which helps reduce fluctuations in vacuum level caused by temperature changes, thereby effectively improving the equipment’s overall operational efficiency and service life. At the same time, it guarantees a stable liquid level and a consistent supply of working fluid during continuous operation, avoiding performance degradation caused by insufficient water supply.
Product Details:
2BV series vacuum pumps with a water tank generate a stabilized liquid ring along the inner wall of the pump chamber through the centrifugal force produced by the high-speed rotation of the impeller. As the volume of the sealed space formed between the impeller blades continuously changes with rotation, gas is drawn into the pump chamber when the volume gradually increases. With the continued rotation of the impeller, the volume continuously decreases, compressing the drawn-in gas until it is ultimately discharged, thereby continuously maintaining a stable vacuum environment. After the discharged liquid enters the water tank, it undergoes gas-liquid separation and natural cooling before re-entering the vacuum pump, enabling a closed-loop operation.

Application:
2BV sugar processing vacuum pump delivers excellent performance in pumping air, water vapor, and various industrial gases that do not contain large amounts of solid particles and are unlikely to undergo violent chemical reactions with the working fluid. As a result, it is effectively utilized in fields such as chemical processing, power generation, environmental protection, papermaking, metallurgy, textiles, pharmaceuticals, vacuum packaging, vacuum filtration, and evaporation and concentration. The product also allows for the selection of corrosion-resistant materials and seals tailored to specific operating conditions to meet the process requirements of various applications.
Feature:
1. It equipped with water tanks offer significant economic advantages, as their recirculation system effectively reduces water consumption on the production floor and lowers wastewater treatment costs, making them ideal for use in water-scarce regions.
2. The stable temperature of the recirculating fluid improves the vacuum pump’s operating conditions, reduces the likelihood of cavitation, and enhances pumping efficiency, enabling the equipment to withstand prolonged continuous operation.
3. Whether used as standalone equipment or as part of a large-scale vacuum system, this series of equipment provides a stable and reliable vacuum environment, thereby improving production efficiency.
4. The equipment features a compact overall design and high transmission efficiency, with minimal vibration and low noise during operation, meeting the stability requirements of industrial production.
