Liquid Ring Type Vacuum Pumps (2BE3) / Water Ring Vacuum Pump

August 09, 2025

**Water Ring Vacuum Pumps (2BE3)** **Liquid Ring Vacuum Pump**
Greentech International (Zhangqiu) Co., Ltd is a leading supplier of high-quality vacuum pumps. Our 2BE3 series water ring vacuum pumps are designed with advanced technology, offering energy efficiency and long-term reliability. These pumps are ideal for rough vacuum applications and are widely used in industries such as papermaking, mining, power plants, and chemical processing. The 2BE3 series can be driven by various configurations, including V-belt, synchronous motor, or gear box. Multiple pumps can be driven by a single motor to save space and improve efficiency. With an internal baffle, the pump can operate under different vacuum conditions on each side, effectively functioning like two pumps at once, enhancing operational flexibility. Key features of the 2BE3 series include: - Large inspection ports on both ends for easy monitoring of wear, corrosion, and dirt. - Flanges on the top and sides for convenient connection with other 2BE3 models. - High-quality imported bearings for precise operation and stability. - Impellers made from QT400 nodular iron or steel plates for durability in harsh environments. - Casing constructed from steel or stainless steel to extend the pump's lifespan. - Stainless steel shaft bushings that increase pump longevity by up to five times compared to standard materials. - High-precision V-belt pulleys with taper bushings for reliable performance and easy maintenance. - A unique separator design above the pump to reduce noise and save space. - All cast parts are produced using resin sand, resulting in a smooth surface and efficient heat dissipation. - Optional imported mechanical seals to prevent leakage during prolonged use.
