**Water Ring Vacuum Pumps (2BE3)** **Liquid Ring Vacuum Pump** Liquid Ring Type Vacuum Pumps (2BE3) / Water Ring Vacuum Pump
Greentech International (Zhangqiu) Co., Ltd is a professional supplier of vacuum pumps. Our 2BE3 series water ring vacuum pumps and compressors are developed using advanced foreign technology, offering energy efficiency and long-term stable operation. These pumps are ideal for rough vacuum applications and can handle various gases. They are widely used in industries such as papermaking, mining, power stations, and chemical processing. The 2BE3 series is designed to be flexible, allowing multiple pumps to be driven by a single motor, saving space and improving efficiency. With an internal partition wall, the pump can operate under different vacuum conditions on both sides, effectively doubling its functionality. This enhances operational flexibility and reliability. Key features of the 2BE3 series include: - Large inspection ports for easy observation of wear, corrosion, and dirt. - Flanges on both top and side for convenient connection with other 2BE3 models. - High-quality imported bearings ensure precise alignment and stability during operation. - Impeller made from QT400 nodular iron or steel plates for durability under harsh conditions. - Casing constructed from steel or stainless steel to extend pump life. - Stainless steel shaft bushings increase pump longevity by up to five times. - High-precision V-belt pulleys with taper bushings ensure reliable performance and easy maintenance. - A separator mounted above the pump saves space and reduces noise. - All spare parts are cast using resin sand, resulting in a smooth surface and efficient heat dissipation. - Optional high-quality mechanical seals prevent leakage during prolonged use.
