Product Description
Summarize:
Models 2BV and SK are CHINAMFG liquid ring vacuum pumps.
Model 2SK is double stages liquid ring vacuum pump.
The liquid-ring vacuum pump compresses gas by rotating a vaned impeller within a cylindrical casing. Liquid (usually water) is fed into the pump, and by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. This liquid ring creates a series of seals in the space between the impeller vanes, which form compression chambers. The eccentricity between the impeller’s axis of rotation and the casing geometric axis results in a cyclic variation of the volume enclosed by the vanes and the ring.
Gas, often air, is drawn into the pump through an inlet port in the end of the casing. The gas is trapped in the compression chambers formed by the impeller vanes and the liquid ring. The reduction in volume caused by the impeller rotation compresses the gas, which reports to the discharge port in the end of the casing.
Compressed gas on discharge of pump contains certain amount of working liquid which is usually removed in vapor-liquid separator.

How Do Vacuum Pumps Assist in Freeze-Drying Processes?
Freeze-drying, also known as lyophilization, is a dehydration technique used in various industries, including pharmaceutical manufacturing. Vacuum pumps play a crucial role in facilitating freeze-drying processes. Here’s a detailed explanation:
During freeze-drying, vacuum pumps assist in the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. The freeze-drying process involves three main stages: freezing, primary drying (sublimation), and secondary drying (desorption).
1. Freezing: In the first stage, the pharmaceutical product is frozen to a solid state. Freezing is typically achieved by lowering the temperature of the product below its freezing point. The frozen product is then placed in a vacuum chamber.
2. Primary Drying (Sublimation): Once the product is frozen, the vacuum pump creates a low-pressure environment within the chamber. By reducing the pressure, the boiling point of water or solvents present in the frozen product is lowered, allowing them to transition directly from the solid phase to the vapor phase through a process called sublimation. Sublimation bypasses the liquid phase, preventing potential damage to the product’s structure.
The vacuum pump maintains a low-pressure environment by continuously removing the water vapor or solvent vapor generated during sublimation. The vapor is drawn out of the chamber, leaving behind the freeze-dried product. This process preserves the product’s original form, texture, and biological activity.
3. Secondary Drying (Desorption): After the majority of the water or solvents have been removed through sublimation, the freeze-dried product may still contain residual moisture or solvents. In the secondary drying stage, the vacuum pump continues to apply vacuum to the chamber, but at a higher temperature. The purpose of this stage is to remove the remaining moisture or solvents through evaporation.
The vacuum pump maintains the low-pressure environment, allowing the residual moisture or solvents to evaporate at a lower temperature than under atmospheric pressure. This prevents potential thermal degradation of the product. Secondary drying further enhances the stability and shelf life of the freeze-dried pharmaceutical product.
By creating and maintaining a low-pressure environment, vacuum pumps enable efficient and controlled sublimation and desorption during the freeze-drying process. They facilitate the removal of water or solvents while minimizing the potential damage to the product’s structure and preserving its quality. Vacuum pumps also contribute to the overall speed and efficiency of the freeze-drying process by continuously removing the vapor generated during sublimation and evaporation. The precise control provided by vacuum pumps ensures the production of stable and high-quality freeze-dried pharmaceutical products.
