2BE1 series water ring vacuum pumps and compressors are highly efficient and energy-saving products developed by our company based on the advanced technology of imported products. This series of pumps has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving. Compared with the SK, 2SK, and SZ series water ring vacuum pumps widely used in China, have remarkable advantages such as high vacuum degree, low power consumption, reliable operation, etc., and are ideal replacement products for SK, 2SK and SZ series water ring vacuum pumps. The main characteristics of the “Zhongni brand” 2BE1 series water ring vacuum pump and compressor produced by our company are as follows: the bearings are all made of original imported bearings, which ensures the precise positioning of the impeller of the 2BE1 vacuum pump and the high stability during operation. The impeller materials are all made of ductile iron casting or steel plate welding, which fully guarantees the stability of the 2BE1 vacuum pump impeller under various harsh working conditions, and greatly improves the service life of the 2BE1 vacuum pump. The pump body is all made of steel plate, which increases the service life of the 2BE1 vacuum pump. As the most vulnerable part, the shaft sleeve of 2BE1 vacuum pump is made of high chromium stainless steel, which is 5 times longer than that of ordinary materials. The belt pulley (belt drive) adopts standard high-precision taper sleeve pulley, reliable operation, long belt life, and easy disassembly. Coupling (direct transmission) adopts standard high-strength elastic coupling, elastic components are made of polyurethane, stable and reliable operation, and long service life. The unique top-mounted air and water separator saves space and effectively reduces noise. All castings are made of resin sand, and the surface quality is good. The surface of the casting does not need to be greasy, which guarantees the heat dissipation effect of the 2BE1 vacuum pump. All mechanical seals (optional accessories) are imported, which fully guarantees that the 2BE1 series vacuum pump has no leakage during long-term operation. The pump body wall profile adopts an approximately elliptical profile to ensure efficient pumping effect.
