2BE1 Series Liquid Ring Vacuum Pump

2BE series liquid ring vacuum pumps are usually used to suction the gas without solid particles, undissolved, and noncorrosive gas to generate vacuum and pressure in the closed container. Changing the pump material can also be used to suction corrosive gas or use the corrosive liquid as an operating liquid. They are widely used in paper-making, chemical, petrification, light industry, pharmacy, instruments, metallurgy, construction, electronical appliance, coal-cleaning, mineral concentration, fertilizer, etc.

2BE liquid ring vacuum pump is a single-stage pump with a simple structure. It’s easy maintenance, reliable, efficient, and energy-saving operation. They can run under harsh working conditions with large drainage discharge and changing load impact. 2BE vacuum pumps adopt unique polytetrafluoroethylene valve plates (former liquid ring pumps use ball valves) for their exhausting systems. Each valve plate is covered by vents on the outer side of a port plate and fixed by a stainless steel baffle on its other side. The curvature of the valve plate changes with inlet pressure so that the pumping medium can be discharged when it reaches the inlet pressure. Such a structure avoids over-compression in a vacuum system and automatically adjusts exhausting areas to lower power consumption. Thus the best operating efficiency can be obtained.

Features of 2BE1 Series Liquid Ring Vacuum Pump

The critical parts of 2BE series liquid ring vacuum pumps, such as the distribution plate, impeller, and pump shaft, are simplified in structure with improved performance. Thus it’s very energy-saving.

The dynamic balance problem is radically solved because blades are formed by one-step stamping with rational molded lines during impeller welding, and all wheel hubs are processed. The impeller and pump shaft, combined with shrinkage interference, perform reliably and smoothly. The blades of the impeller will obtain good ductility after the impeller is welded and processed by overall heat treatment; thus, impact resistance and flexure resistance of the blades are fundamentally guaranteed for the application under challenging working conditions with changing load impact.

The 2BE pumps are equipped with gas-water separators themselves; Many positions have an exhausting hole. It is straightforward to connect with the vacuum system; what’s more, the pump is covered with an inspection window which can regulate the gland packing of the shaft to adjust the impeller and to distribute the plate. All vacuum pumps will be subjected to strict inspections and tests in our testing center to guarantee their excellent, reliable, and long-lasting performances.
