Overview    
The 2BE3 liquid ring vacuum pumps and compressors are high-efficient and energy-saving products developed by our company on the basis of our scientific achievements and production experiences over the years and internationally advanced technique of similar products. They have low vacuum and high extraction capacity and are usually applied to exhausting water insoluble, noncorrosive and solid particle-free gases for creating vacuum and pressure in closed containers. They are also applicable for corrosive gases, or corrosive liquid can be used as treatment fluid by modifying materials of parts. The products are being widely used in fields of paper making, chemistry, pharmacy, coal dressing, mineral separation, petrochemistry, light industry, food, metallurgy, building material, stoneware and chemical fertilizer due to their outstanding and reliable performances and durability.

Compared with 2BE1 series, 2BE3 series are different in the following aspects: 
They have higher suction capacity and lower vacuum, thus they are suitable for operations requiring large suction capacity such as mine gas discharge and pressure swing adsorption for chemical plants. 
Cylindrical ball bearings are replaced by double-row tapered roller bearings, thus service lives of the bearings are prolonged and load carrying capacities are improved.
The‘concave-convex connector’for locating the pump and distribution plate is replaced by‘two pins on one surface’. The stop pins ensure the radial clearance between the impeller and pump. 
Air inlets and vents are arranged on both top and side end of the pump cover. In case that the gas shall be filled or discharged from the top, the side air inlets and vents are sealed by blank caps, thus there are more assembly options.
High voltage motor may be available for the 2BE3 series since their energy consumptions and powers are increased due to large volumes and large suction capacities. The transmission is usually carried out by reducers. Pumps 50/52 may use belt transmission while pump 60 and superior ones shall adopt reducers for transmission. 
2BE3 series have additional eccentric clapboards for dividing the pumps into two chambers with impeller middle plates. Air inlets and vents on side flanges make one pump adequate for operations requiring two pressure points, such as paper making.


Water ring vacuum pump: mode expression method 

Models of 2BE3 series are expressed by 7 words (letters) and numbers as follows:

2BE3-- <1><2> -<3>

2BE3 is the name of the single-stage water ring vacuum series and 3 stands for 2BE low vacuum series;

<1><2> stands for nominal radius (cm) of the impeller; and

<3> stands for code of minimal suction pressure, specifically, 0 stands for limiting vacuum of 33hpa and 1 stands for limiting vacuum of 160hpa.     

For example, "2BE3-40-1" stands for a single-stage liquid ring vacuum pump in which nominal diameter of the impeller is 800mm and minimal absolute suction pressure can reach 160hPa. Such pump can also be recorded as 2BE3-40 (since limiting vacuum of 2BE1 series is 33hpa and that of 2BE3 series is 160hpa, the <4> is usually ignored).

 Note: 
The suction capacity in the table is maximal capacity. Actual speed of exhaust changes with the suction pressure. Specific operating pressure and the performance curves shall be considered when selecting pumps.


Motor powers of the vacuum pumps are appropriate in most cases, but shall be increased accordingly when vent pressures (gage pressure 0.04-0.12MPa) are high so as to suit to the function as liquid ring compressors. The table also includes performance curves of the pumps when they function as compressors. Pumps can be selected according to the curves in case of such situation.

Water consumptions of the pumps under different pressures are shown by the performance curves.


2BE3-80N is an ultra-large water ring pump independently developed by our company on the basis of foreign advanced products, possessing an extraction capacity of 40000 m3/h. It is applied to operations requiring large extraction capacity such as mine gas discharge.


2BE series are usually used in combination with front separators, rear separators and heat exchangers. The integral water ring pump units manufactured by our company can be referred for type selection.
