2BE1 Liquid Ring Vacuum Pump

The 2BE1 Liquid Ring Vacuum Pump is a single-stage, single-acting water ring vacuum pump designed for reliable vacuum generation across a wide range of industrial applications. Developed for demanding continuous-duty service, the 2BE1 series combines a simple construction with convenient maintenance, efficient operation, and flexible material configurations for different process media.

Through continuous development, the 2BE1 series has expanded from its original 12 specifications to 22 specifications, providing a broader selection of capacities and configurations for different industrial vacuum requirements.

The pump is suitable for applications requiring relatively high vacuum conditions and can be configured with different wetted-end materials, including carbon steel and cast iron, SS304, SS304L, SS316L, duplex stainless steel, titanium alloy, Hastelloy, and other materials according to process requirements.

Product Introduction

The 2BE1 series is a single-stage, single-acting liquid ring vacuum pump featuring axial suction and discharge. Its straightforward construction helps simplify installation, operation, inspection, and maintenance.

The pump is designed to operate with water or other suitable working fluids and can be equipped with a heat exchanger to enable working-fluid recycling, helping reduce water consumption.

Key Features

Simple and Reliable Construction

The single-stage, single-acting configuration with axial intake and exhaust provides a straightforward structure and convenient maintenance. The pump is suitable for continuous industrial operation where reliable vacuum performance is required.

Automatic Exhaust Adjustment

The exhaust port is equipped with a flexible valve plate that automatically adjusts the exhaust angle according to suction conditions. This helps maintain efficient pump operation across different vacuum conditions.

Automatic Drain Valve

An automatic drain valve controls the starting liquid level of the pump, helping prevent overload during startup and improving operational reliability.

Improved Impeller Design

The impeller end face uses a graded design that reduces the pump's sensitivity to dust and water scaling in the operating medium. Improvements to the impeller ring and overall impeller structure also allow the extracted gas to contain non-granular dust.

Convenient Packing Maintenance

The packing gland uses a half-structure design that can be removed as a complete assembly, making packing replacement and maintenance more convenient.
