The details of this product are relatively simple and clear. The manufacturer has several explanations regarding this:
1. Regarding product quality. Our factory has been established for nearly 25 years, focusing on the production of water ring vacuum pumps and vacuum pump units. During this period, we have never produced other types of pumps, and we always choose the best accessories. We strictly test the vacuum degree, pumping volume, motor condition, pump operation, etc. before leaving the factory, which is known as "our advantages or why we are chosen". Our factory believes that there is no need or energy to present this in exquisite pictures.
2. Regarding after-sales service: The product has a one-year warranty, and our after-sales team consists of many experienced employees with strong professionalism. There are no after-sales problems that are pushed to customers or caused by working conditions, and we are responsible and conscientious (just selling without repairing cannot last for 25 years). Our factory believes that it is not necessary to present this in the form of exquisite images.
3. Regarding the details of this product, based on years of production and sales experience and customer concerns, our factory has designed a relatively simple design, including company introduction, product structure, operating principle, parameters, application scope, etc. (directly include the details related to these points in the product sample). If you need a size chart, you can refer to the attached manual or consult our factory directly. There is no need to cover everything.
4. In addition to the main image of this product, there are physical images and related videos in the details,All photos were taken in the workshop without any modifications except for adding our factory watermark. Advocate for practicality and oppose extravagance without substance.The vacuum pump was not invented by any manufacturer. If the assembly accuracy is accurate, the parameters will be the same, only there will be differences in the quality of the accessories.
5. Regarding the price:The 2BE series water ring vacuum pump comes with multiple power options for each model, corresponding to different pumping volumes (details provided). Therefore, the motor prices are different and the overall price cannot be indicated. In addition, the raw materials fluctuate frequently, and some customers do not require tax invoices. Therefore, the listed price is the pump head reference price (excluding tax). Please negotiate based on the regional shipping cost, whether it includes tax and whether it is a complete machine.
In conclusionMake pumps solidly and sell them practically.Welcome new and old customers to inquire and purchase.

Product Overview of 2BE Water Ring Vacuum Pump:
The 2BE water ring vacuum pump and compressor developed by our company is an efficient and energy-saving product based on years of scientific research and production experience, combined with advanced technology of similar international products. It is usually used to pump gases that do not contain solid particles, are insoluble in water, and are non corrosive, in order to form a vacuum and pressure in a closed container. By changing the result material, it can also be used to extract corrosive gases or use corrosive liquids as working fluids. The 2BE water ring vacuum pump is widely used in industries such as papermaking, chemical, petrochemical, light industry, food, metallurgy, building materials, stone tools, coal washing, mineral processing, and fertilizer.
The 2BE water ring vacuum pump adopts a single-stage single action structure, which has the advantages of simple structure, easy maintenance, reliable operation, high efficiency and energy saving, and can adapt to harsh working conditions such as large drainage volume and load impact fluctuations.
We have systematically optimized the key components of the 2BE water ring vacuum pump, such as the distribution plate, impeller, and pump shaft, simplifying the structure, improving performance, and achieving energy savings. The impeller is welded, and the blades are stamped and formed in one go with a reasonable profile; The complete processing of the hub fundamentally solves the problem of dynamic balance. The impeller and pump shaft adopt a hot fit interference fit, with reliable performance and smooth operation. After the impeller is welded, the overall operation is well heat treated, and the blades have good toughness, which fundamentally guarantees the impact resistance and bending resistance of the blades. The 2BE water ring vacuum pump can adapt to harsh working conditions with load impact fluctuations.
The 2BE type water ring vacuum pump comes with a gas water separator, but there are no exhaust ports in multiple positions. The pump cover is equipped with an exhaust valve maintenance window, and the gap between the impeller and the distribution plate is adjusted by pressing the covers at both ends of the positioning shaft. It is easy to install, operate, and maintain.
Application range of 2BE water ring vacuum pump:
1. The 2BE water ring vacuum pump is capable of long-term continuous operation within the ambient temperature range of 5-40 ℃ and under inlet pressure less than 1330Pa.
2. The 2BE type water ring vacuum pump is not suitable for extracting gases with high oxygen content, toxicity, explosiveness, corrosive effects on metals, chemical reactions on pump oil, or gases containing particles and dust. It is also not suitable for transporting gases from one container to another as a transport pump.
3. The continuous working time of the 2BE water ring vacuum pump under inlet pressure ranging from atmospheric pressure to 6000Pa should not exceed 3 minutes to avoid pump damage caused by oil injection or poor lubrication.
2BE type water ring vacuum pump model meaning:


The 2BE water ring vacuum pump has significant advantages over the widely used SK, 2SK, and SZ series water ring vacuum pumps in China, such as high vacuum degree and low power consumption. It is an ideal substitute for the SK, 2SK, and SZ series water ring vacuum pumps. The main structural features of the 2BE water ring vacuum pump and compressor produced by our company are as follows:
1. All bearings are imported with original equipment, ensuring precise positioning of the impeller and high stability during operation of the 2BE water ring vacuum pump.
2. The impeller material is all cast with ductile iron or welded with steel plates, fully ensuring the stability of the 2BE water ring vacuum pump impeller under various harsh working conditions, and greatly improving the service life of the 2BE water ring vacuum pump.
4. The pump body is entirely made of steel plates, which improves the service life of the 2BE water ring vacuum pump.
5. The shaft sleeve of the 2BE water ring vacuum pump is a vulnerable component, and our company uses high chromium stainless steel for all parts, which increases the service life by 5 times compared to ordinary materials.
6. The 2BE water ring vacuum pump belt pulley (belt drive) adopts a standard high-precision cone sleeve belt pulley, which runs reliably, has a long belt life, and is easy to disassemble.
7. The 2BE water ring vacuum pump coupling (direct drive) adopts a standard high-strength elastic coupling, and the elastic element is made of polyurethane material, which runs stably and reliably with a long service life.
8. The unique upward mounted air-water separator saves space and effectively reduces the noise of the 2BE water ring vacuum pump.
9. All castings are made of resin sand casting, with good surface quality. The surface of the casting does not need to be greased, making the 2BE water ring vacuum pump have better heat dissipation effect.
10. All mechanical seals (optional accessories) are imported, fully ensuring that the 2BE water ring vacuum pump has no leakage during long-term operation.
11. The inner wall profile of the 2BE water ring vacuum pump adopts an approximately elliptical profile to ensure better pumping effect.
