Product Description
The application range and characteristics:
2BE3 series water ring vacuum pumps and compressors are designed and manufactured by our company integrating with the advanced technology abroad. They are not only can save energy, but also can work constantly for a long time.
Under the rough vacuum situation, the requirements for the liquid ring vacuum pumps are very rigorous. So the 2BE3 series products are designed for pumping various gases. They are widely used in many industries, such as, the paper, mine, power station, chemical etc.
2BE3 series products can be driven with many different sets, such as, the V-belt, synchronal motor, gear box etc. In order to save space, more than 2 or at most 4 sets of the 2BE3 series pumps can be driven by 1 motor simultaneously.
When set a middle wall in the casing, the pressure tolerance between the 2 sides is lower than 80kPa and the 2 parts can work in different vacuum status respectively. Thus 1 pump can work well like two. Hereby the product operating flexibility is improved effectively.
The main characteristics of 2BE3 series products:
· The tolerance, corrosive status, and the begrime situation can be easily observed by the big inspection port on both sides of the end-shield.
· The 2BE3 series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BE3 series pumps.
· The bearings are all used of the imported products in order to keep the precise orientation and the high stability during the working of the pump.
· The material of the impeller is QT400 nodular iron or steel plates for ensuring the stability of the pump under the various rigorous situations and extending the life of the pump effectively.
· The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE3 series pumps.
· The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material.
· The V-belt pulley (when the pump is driven by the belt) is used of the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
· The unique design of setting the separator above the pump saves the space and decreases the noise efficiently.
· All the spare parts are cast by the resin sands that make the surface of the pump very smooth. So it is not necessary to cover the surface of the pump with putty and gives out the heat efficiently.
· The mechanical seals (optional) are all used the imported products so as to avoid the leakage during the working of the pump for a long time.

Semiconductor manufacturing involves the production of integrated circuits (ICs) and other semiconductor devices used in various electronic applications. Vacuum pumps are used extensively throughout the semiconductor manufacturing process to create and maintain the required vacuum conditions for specific manufacturing steps.
Here are some key roles of vacuum pumps in semiconductor manufacturing:
1. Deposition Processes: Vacuum pumps are used in deposition processes such as physical vapor deposition (PVD) and chemical vapor deposition (CVD). These processes involve depositing thin films of materials onto semiconductor wafers to create various layers and patterns. Vacuum pumps help create a low-pressure environment necessary for precise control of the deposition process, ensuring uniform and high-quality film formation.
2. Etching and Cleaning: Vacuum pumps are utilized in etching and cleaning processes, which involve the removal of specific layers or contaminants from semiconductor wafers. Dry etching techniques, such as plasma etching and reactive ion etching, require a vacuum environment to facilitate the ionization and removal of material. Vacuum pumps aid in creating the necessary low-pressure conditions for efficient etching and cleaning processes.
3. Ion Implantation: Ion implantation is a process used to introduce impurities into specific regions of a semiconductor wafer to modify its electrical properties. Vacuum pumps are used to evacuate the ion implantation chamber, creating the required vacuum environment for accurate and controlled ion beam acceleration and implantation.
4. Wafer Handling and Transfer: Vacuum pumps are employed in wafer handling and transfer systems. These systems utilize vacuum suction to securely hold and manipulate semiconductor wafers during various manufacturing steps, such as loading and unloading from process chambers, robotic transfer between tools, and wafer alignment.
5. Load Lock Systems: Load lock systems are used to transfer semiconductor wafers between atmospheric conditions and the vacuum environment of process chambers. Vacuum pumps are integral components of load lock systems, creating and maintaining the vacuum conditions necessary for wafer transfer while minimizing contamination risks.
6. Metrology and Inspection: Vacuum pumps are utilized in metrology and inspection tools used for characterizing semiconductor devices. These tools, such as scanning electron microscopes (SEMs) and focused ion beam (FIB) systems, often operate in a vacuum environment to enable high-resolution imaging and accurate analysis of semiconductor structures and defects.
7. Leak Detection: Vacuum pumps are employed in leak detection systems to identify and locate leaks in vacuum chambers, process lines, and other components. These systems rely on vacuum pumps to evacuate the system and then monitor for any pressure rise, indicating the presence of leaks.

Overall, vacuum pumps are indispensable in semiconductor manufacturing, enabling the creation of the necessary vacuum conditions for various processes, ensuring the production of high-quality semiconductor devices.
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.
Can Vacuum Pumps Be Used in Food Processing?
Yes, vacuum pumps are widely used in food processing for various applications. Here’s a detailed explanation:
Vacuum pumps play a crucial role in the food processing industry by enabling the creation and maintenance of vacuum or low-pressure environments. They offer several benefits in terms of food preservation, packaging, and processing. Here are some common applications of vacuum pumps in food processing:
1. Vacuum Packaging: Vacuum pumps are extensively used in vacuum packaging processes. Vacuum packaging involves removing air from the packaging container to create a vacuum-sealed environment. This process helps extend the shelf life of food products by inhibiting the growth of spoilage-causing microorganisms and reducing oxidation. Vacuum pumps are used to evacuate the air from the packaging, ensuring a tight seal and maintaining the quality and freshness of the food.
2. Freeze Drying: Vacuum pumps are essential in freeze drying or lyophilization processes used in food processing. Freeze drying involves removing moisture from food products while they are frozen, preserving their texture, flavor, and nutritional content. Vacuum pumps create a low-pressure environment that allows frozen water to directly sublimate from solid to vapor, resulting in the removal of moisture from the food without causing damage or loss of quality.
3. Vacuum Cooling: Vacuum pumps are utilized in vacuum cooling processes for rapid and efficient cooling of food products. Vacuum cooling involves placing the food in a vacuum chamber and reducing the pressure. This lowers the boiling point of water, facilitating the rapid evaporation of moisture and heat from the food, thereby cooling it quickly. Vacuum cooling helps maintain the freshness, texture, and quality of delicate food items such as fruits, vegetables, and bakery products.
4. Vacuum Concentration: Vacuum pumps are employed in vacuum concentration processes in the food industry. Vacuum concentration involves removing excess moisture from liquid food products to increase their solids content. By creating a vacuum, the boiling point of the liquid is reduced, allowing for gentle evaporation of water while preserving the desired flavors, nutrients, and viscosity of the product. Vacuum concentration is commonly used in the production of juices, sauces, and concentrates.
5. Vacuum Mixing and Deaeration: Vacuum pumps are used in mixing and deaeration processes in food processing. In the production of certain food products such as chocolates, confectioneries, and sauces, vacuum mixing is employed to remove air bubbles, achieve homogeneity, and improve product texture. Vacuum pumps aid in the removal of entrapped air and gases, resulting in smooth and uniform food products.
6. Vacuum Filtration: Vacuum pumps are utilized in food processing for vacuum filtration applications. Vacuum filtration involves separating solids from liquids or gases using a filter medium. Vacuum pumps create suction that draws the liquid or gas through the filter, leaving behind the solid particles. Vacuum filtration is commonly used in processes such as clarifying liquids, removing impurities, and separating solids from liquids in the production of beverages, oils, and dairy products.
7. Marinating and Brining: Vacuum pumps are employed in marinating and brining processes in the food industry. By applying a vacuum to the marinating or brining container, the pressure is reduced, allowing the marinade or brine to penetrate the food more efficiently. Vacuum marinating and brining help enhance flavor absorption, reduce marinating time, and improve the overall taste and texture of the food.
8. Controlled Atmosphere Packaging: Vacuum pumps are used in controlled atmosphere packaging (CAP) systems in the food industry. CAP involves modifying the gas composition within food packaging to extend the shelf life and maintain the quality of perishable products. Vacuum pumps aid in the removal of oxygen or other unwanted gases from the package, allowing the introduction of a desired gas mixture that preserves the food’s freshness and inhibits microbial growth.
These are just a few examples of how vacuum pumps are used in food processing. The ability to create and control vacuum or low-pressure environments is a valuable asset in preserving food quality, enhancing shelf life, and facilitating various processing techniques in the food industry.
