Product Description
Application scope and characteristics:
Greentech International (Xihu (West Lake) Dis.) Co., Ltd is the professional vacuum pump supplier. 2BE1 series water ring vacuum pumps and compressors are the products with high efficiency and economic power, which are manufactured by our company integrating with the advanced technology of the imported products from Germany.
These series products adopt CHINAMFG and single action structure and have many advantages, such as, compact structure, convenient maintenance, reliable running, high efficiency and economic power.
The main characteristics of 2BE1 series products:
All the bearings are the imported products with the brand name of CHINAMFG orNTN for ensuring the precise orientation and the high stability during the working of the pump.
The material of the impeller is QT400 nodular iron or stainless steel for ensuring the stability when the pump works under the rigorous condition and can extend the lifetime of the pump.
The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE1 series pumps.
The shaft bushing is made of stainless steel to improve the lifetime of the pump 5 times than the normal material.
The V-belt pulley (when the pump is driven by the belt) is used 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 coupling is used to drive the pump directly. The flexible part connecting the 2 half coupling is made of polyurethane that makes the pump more reliable.
The unique design to set the separator above the pump saves the space and decreases the noise efficiently.
All the parts are cast by the resin sands that make the pump surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.
The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.

What Is the Impact of Altitude on Vacuum Pump Performance?
The performance of vacuum pumps can be influenced by the altitude at which they are operated. Here’s a detailed explanation:
Altitude refers to the elevation or height above sea level. As the altitude increases, the atmospheric pressure decreases. This decrease in atmospheric pressure can have several effects on the performance of vacuum pumps:
1. Reduced Suction Capacity: Vacuum pumps rely on the pressure differential between the suction side and the discharge side to create a vacuum. At higher altitudes, where the atmospheric pressure is lower, the pressure differential available for the pump to work against is reduced. This can result in a decrease in the suction capacity of the vacuum pump, meaning it may not be able to achieve the same level of vacuum as it would at lower altitudes.
2. Lower Ultimate Vacuum Level: The ultimate vacuum level, which represents the lowest pressure that a vacuum pump can achieve, is also affected by altitude. As the atmospheric pressure decreases with increasing altitude, the ultimate vacuum level that can be attained by a vacuum pump is limited. The pump may struggle to reach the same level of vacuum as it would at sea level or lower altitudes.
3. Pumping Speed: Pumping speed is a measure of how quickly a vacuum pump can remove gases from a system. At higher altitudes, the reduced atmospheric pressure can lead to a decrease in pumping speed. This means that the vacuum pump may take longer to evacuate a chamber or system to the desired vacuum level.
4. Increased Power Consumption: To compensate for the decreased pressure differential and achieve the desired vacuum level, a vacuum pump operating at higher altitudes may require higher power consumption. The pump needs to work harder to overcome the lower atmospheric pressure and maintain the necessary suction capacity. This increased power consumption can impact energy efficiency and operating costs.
5. Efficiency and Performance Variations: Different types of vacuum pumps may exhibit varying degrees of sensitivity to altitude. Oil-sealed rotary vane pumps, for example, may experience more significant performance variations compared to dry pumps or other pump technologies. The design and operating principles of the vacuum pump can influence its ability to maintain performance at higher altitudes.
It’s important to note that vacuum pump manufacturers typically provide specifications and performance curves for their pumps based on standardized conditions, often at or near sea level. When operating a vacuum pump at higher altitudes, it is advisable to consult the manufacturer’s guidelines and consider any altitude-related limitations or adjustments that may be necessary.
In summary, the altitude at which a vacuum pump operates can have an impact on its performance. The reduced atmospheric pressure at higher altitudes can result in decreased suction capacity, lower ultimate vacuum levels, reduced pumping speed, and potentially increased power consumption. Understanding these effects is crucial for selecting and operating vacuum pumps effectively in different altitude environments.
What Is the Difference Between Dry and Wet Vacuum Pumps?
Dry and wet vacuum pumps are two distinct types of pumps that differ in their operating principles and applications. Here’s a detailed explanation of the differences between them:
Dry Vacuum Pumps:
Dry vacuum pumps operate without the use of any lubricating fluid or sealing water in the pumping chamber. They rely on non-contact mechanisms to create a vacuum. Some common types of dry vacuum pumps include:
1. Rotary Vane Pumps: Rotary vane pumps consist of a rotor with vanes that slide in and out of slots in the rotor. The rotation of the rotor creates chambers that expand and contract, allowing the gas to be pumped. The vanes and the housing are designed to create a seal, preventing gas from flowing back into the pump. Rotary vane pumps are commonly used in laboratories, medical applications, and industrial processes where a medium vacuum level is required.
2. Dry Screw Pumps: Dry screw pumps use two or more intermeshing screws to compress and transport gas. As the screws rotate, the gas is trapped between the threads and transported from the suction side to the discharge side. Dry screw pumps are known for their high pumping speeds, low noise levels, and ability to handle various gases. They are used in applications such as semiconductor manufacturing, chemical processing, and vacuum distillation.
3. Claw Pumps: Claw pumps use two rotors with claw-shaped lobes that rotate in opposite directions. The rotation creates a series of expanding and contracting chambers, enabling gas capture and pumping. Claw pumps are known for their oil-free operation, high pumping speeds, and suitability for handling dry and clean gases. They are commonly used in applications such as automotive manufacturing, food packaging, and environmental technology.
Wet Vacuum Pumps:
Wet vacuum pumps, also known as liquid ring pumps, operate by using a liquid, typically water, to create a seal and generate a vacuum. The liquid ring serves as both the sealing medium and the working fluid. Wet vacuum pumps are commonly used in applications where a higher level of vacuum is required or when handling corrosive gases. Some key features of wet vacuum pumps include:
1. Liquid Ring Pumps: Liquid ring pumps feature an impeller with blades that rotate eccentrically within a cylindrical casing. As the impeller rotates, the liquid forms a ring against the casing due to centrifugal force. The liquid ring creates a seal, and as the impeller spins, the volume of the gas chamber decreases, leading to the compression and discharge of gas. Liquid ring pumps are known for their ability to handle wet and corrosive gases, making them suitable for applications such as chemical processing, oil refining, and wastewater treatment.
2. Water Jet Pumps: Water jet pumps utilize a jet of high-velocity water to create a vacuum. The water jet entrains gases, and the mixture is then separated in a venturi section, where the water is recirculated, and the gases are discharged. Water jet pumps are commonly used in laboratories and applications where a moderate vacuum level is required.
The main differences between dry and wet vacuum pumps can be summarized as follows:
1. Operating Principle: Dry vacuum pumps operate without the need for any sealing fluid, while wet vacuum pumps utilize a liquid ring or water as a sealing and working medium.
2. Lubrication: Dry vacuum pumps do not require lubrication since there is no contact between moving parts, whereas wet vacuum pumps require the presence of a liquid for sealing and lubrication.
3. Applications: Dry vacuum pumps are suitable for applications where a medium vacuum level is required, and oil-free operation is desired. They are commonly used in laboratories, medical settings, and various industrial processes. Wet vacuum pumps, on the other hand, are used when a higher vacuum level is needed or when handling corrosive gases. They find applications in chemical processing, oil refining, and wastewater treatment, among others.
It’s important to note that the selection of a vacuum pump depends on specific requirements such as desired vacuum level, gas compatibility, operating conditions, and the nature of the application.
In summary, the primary distinction between dry and wet vacuum pumps lies in their operating principles, lubrication requirements, and applications. Dry vacuum pumps operate without any lubricating fluid, while wet vacuum pumps rely on a liquid ring or water for sealing and lubrication. The choice between dry and wet vacuum pumps depends on the specific needs of the application and the desired vacuum level.
Can Vacuum Pumps Be Used in Laboratories?
Yes, vacuum pumps are extensively used in laboratories for a wide range of applications. Here’s a detailed explanation:
Vacuum pumps are essential tools in laboratory settings as they enable scientists and researchers to create and control vacuum or low-pressure environments. These controlled conditions are crucial for various scientific processes and experiments. Here are some key reasons why vacuum pumps are used in laboratories:
1. Evaporation and Distillation: Vacuum pumps are frequently used in laboratory evaporation and distillation processes. By creating a vacuum, they lower the boiling point of liquids, allowing for gentler and more controlled evaporation. This is particularly useful for heat-sensitive substances or when precise control over the evaporation process is required.
2. Filtration: Vacuum filtration is a common technique in laboratories for separating solids from liquids or gases. Vacuum pumps create suction, which helps draw the liquid or gas through the filter, leaving the solid particles behind. This method is widely used in processes such as sample preparation, microbiology, and analytical chemistry.
3. Freeze Drying: Vacuum pumps play a crucial role in freeze drying or lyophilization processes. Freeze drying involves removing moisture from a substance while it is in a frozen state, preserving its structure and properties. Vacuum pumps facilitate the sublimation of frozen water directly into vapor, resulting in the removal of moisture under low-pressure conditions.
4. Vacuum Ovens and Chambers: Vacuum pumps are used in conjunction with vacuum ovens and chambers to create controlled low-pressure environments for various applications. Vacuum ovens are used for drying heat-sensitive materials, removing solvents, or conducting reactions under reduced pressure. Vacuum chambers are utilized for testing components under simulated space or high-altitude conditions, degassing materials, or studying vacuum-related phenomena.
5. Analytical Instruments: Many laboratory analytical instruments rely on vacuum pumps to function properly. For example, mass spectrometers, electron microscopes, surface analysis equipment, and other analytical instruments often require vacuum conditions to maintain sample integrity and achieve accurate results.
6. Chemistry and Material Science: Vacuum pumps are employed in numerous chemical and material science experiments. They are used for degassing samples, creating controlled atmospheres, conducting reactions under reduced pressure, or studying gas-phase reactions. Vacuum pumps are also used in thin film deposition techniques like physical vapor deposition (PVD) and chemical vapor deposition (CVD).
7. Vacuum Systems for Experiments: In scientific research, vacuum systems are often designed and constructed for specific experiments or applications. These systems can include multiple vacuum pumps, valves, and chambers to create specialized vacuum environments tailored to the requirements of the experiment.
Overall, vacuum pumps are versatile tools that find extensive use in laboratories across various scientific disciplines. They enable researchers to control and manipulate vacuum or low-pressure conditions, facilitating a wide range of processes, experiments, and analyses. The choice of vacuum pump depends on factors such as required vacuum level, flow rate, chemical compatibility, and specific application needs.
