    Product description

    　　The 2BE type water ring vacuum pump and compressor is an efficient and energy-saving product developed by our company based on years of scientific research results and production experience, combining advanced technology from similar international products. It is commonly used to suction gases that do not contain solid particles, are not soluble in water, and are not corrosive, in order to create vacuum and pressure in a closed container. By changing the rotor material, it can also be used to suction corrosive gases or use corrosive liquids as the working fluid. The 2BE type water ring vacuum pump is widely used in the paper manufacturing, chemical, petrochemical, light industry, pharmaceutical, food, metallurgical, building materials, stone, coal washing, mineral processing, fertilizer, and other industries.

    Structural features of the 2BE type water ring vacuum pump:

    　 Structural diagram of the 2BE type water ring vacuum pump

    　　The 2BE type water ring vacuum pump adopts a single-stage, single-action structure, with advantages of simple structure, convenient maintenance, reliable operation, and high energy efficiency, and can adapt to adverse conditions such as large discharge volume and load fluctuations caused by shock waves.

    　　We have systematically optimized key parts of the 2BE type water ring vacuum pump, such as the distributor plate, impeller, and pump shaft, simplifying the structure, improving performance, and achieving energy savings. A welded impeller is used, with blades stamped and formed in one piece, with a reasonable profile; all machining is done to fundamentally solve the dynamic balance problem. The impeller and pump shaft adopt an interference fit by heating, with reliable performance and stable operation. After welding the impeller, comprehensive heat treatment is performed for good operation, and the blades have good toughness, fundamentally ensuring resistance to impact and bending of the blades. The 2BE type water ring vacuum pump can adapt to adverse conditions with load fluctuations caused by shock waves.

    　　The 2BE type vacuum pump comes with a built-in gas and water separator, no exhaust outlet in multiple positions, the pump cover has an inspection window for the exhaust valve, and the space between the impeller and the distributor plate is adjusted by press covers at both ends of the positioning shaft, facilitating installation, use, simple operation, and maintenance.

    　　The 2BE type water ring vacuum pump has significant advantages such as a high vacuum degree and low energy consumption compared to the widely used SK, 2SK, and SZ series water ring vacuum pumps in the country, making it an ideal product to replace these series. The main structural features of the 2BE type vacuum pump and compressor produced by our company are as follows:

    　　1. All bearings use original imported bearings, ensuring precise positioning of the impeller and high stability during the operation of the 2BE type water ring vacuum pump.

    　　2. The impeller material is fully cast in ductile iron or welded with steel plate, fully ensuring the stability of the 2BE type water ring vacuum pump impeller under various adverse conditions, and significantly increasing the pump's service life.

    　　4. The pump body is fully made of steel plate, improving the service life of the 2BE type water ring vacuum pump.

    　　5. The sleeve of the 2BE type water ring vacuum pump shaft, as the most wear-prone part, is made entirely of high-chromium stainless steel, increasing its service life five times compared to common materials.

    　　6. The pulley of the 2BE type water ring vacuum pump (belt drive) uses a standard high-precision tapered pulley, with reliable operation, long belt life, and easy disassembly.

    　　7. The coupling of the 2BE type water ring vacuum pump (direct drive) uses a standard high-strength elastic coupling, with polyurethane elastic elements, stable and reliable operation, and long service life.

    　　8. The unique gas and water separator mounted on top saves space and effectively reduces the noise of the 2BE type water ring vacuum pump.

    　　9. All cast parts are made by resin sand casting, with good surface quality. It is not necessary to apply putty on the surface of the cast parts, which improves the heat dissipation effect of the 2BE type water ring vacuum pump.

    　　10. The mechanical seal (optional part) uses fully imported components, ensuring that the 2BE type water ring vacuum pump does not leak during prolonged operation.

    　　11. The inner surface of the 2BE type water ring vacuum pump body uses an approximately elliptical profile to ensure the suction effect.

    Usage range of the 2BE type water ring vacuum pump:

    　　1. The 2BE type water ring vacuum pump can operate continuously for a long time within an ambient temperature range of 5 to 40℃ and with an inlet pressure less than 1330Pa.

    　　2. The 2BE type water ring vacuum pump is not suitable for extracting gases with high oxygen content, toxic, explosive, corrosive to metals, chemically reactive with the pump oil, or gases containing dust particles. It is also not suitable for transporting gases from one container to another as a transfer pump.

    　　3. The 2BE type water ring vacuum pump should not operate continuously for more than 3 minutes under an inlet pressure from atmospheric to 6000Pa to avoid damage caused by oil spray or poor lubrication.

    FAQ

    Q

    What products do you mainly produce?

    A

    Zoomlion Pump Industry manufactures various large industrial centrifugal pumps. The main products include: self-balancing multistage pumps, multistage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condenser pumps, and more.

    Q

    Can you help me choose a model?

    A

    Of course! If the water pump model is not selected accurately, it can cause significant problems. After you take it back, it might be either too small to meet the usage requirements or too large, resulting in higher electricity and fuel costs, increasing the operating expenses.

    Q

    Why is the price quotation so slow?

    A

    Because centrifugal pumps are non-standard custom products with many models and a wide price range. Even for the same model, the price varies greatly depending on the materials and configurations used. Taking the most common pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clearly confirm the relevant information to provide you with an accurate price. Normally, if you provide comprehensive information, we can quote within 5 minutes.

    Q

    What information should I provide when I need a quote?

    A

    Usually, if you want to get an accurate quote, it is recommended that you provide us with the following information: pump flow rate, head, on-site operating voltage, frequency, temperature of the conveyed liquid, pH value, solid particle content, on-site installation conditions (horizontal or vertical installation), and other related details. If you are not very familiar with these, it’s okay; our sales manager will assist you in determining them.

    Q

    Do you have centrifugal pumps in stock?

    A

    There are many models and configurations of centrifugal pumps. Except for a small number of commonly used standard models that are in stock, the vast majority of models and configurations are not stocked and are customized products. We need to first select the pump based on your site conditions such as flow rate, head, medium temperature, pH value, and installation conditions. After determining the pump model and configuration, we can then place an order with the workshop for production.

    Q

    What is your usual delivery time?

    A

    Models in stock can be shipped by the next day at the latest. Others are custom-made, and depending on the product size and specific project conditions, the delivery time is generally between 7-90 days. Please consult our sales manager for details: 0731-88632200 。
