The application range and characteristics:

2BE4 series water ring vacuum pumps and compressors (liquid ring vacuum pump) are designed and manufactured by our company integrating with the advanced technology abroad. They are not only can save energy, but also can work constantly for a long time. Under the rough vacuum situation, the requirements for the liquid ring vacuum pumps are very rigorous. So the 2BE4 series products are designed for pumping various gases.

The main characteristics of 2BE4 series water ring vacuum pump:

1. The tolerance, corrosive status, and the begrime situation can be easily observed by the big inspection port on both sides of the end-shield;

2. The 2BE4 series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BE4 series pumps;

3. The bearings are all used of the imported products in order to keep the precise orientation and the high stability during the working of the pump;

4. The material of the impeller is QT400 nodular iron or steel plates for ensuring the stability of the pump under the various rigorous situations and extending the life of the pump effectively;

5. The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE4 series pumps;

6. The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material;

7. The V-belt pulley (when the pump is driven by the belt) is used of the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle;

8. The unique design of setting the separator above the pump saves the space and decreases the noise efficiently;

9. All the spare parts are cast by the resin sands that make the surface of the pump very smooth. So it is not necessary to cover the surface of the pump with putty and gives out the heat efficiently;

10. The mechanical seals (optional) are all used the imported products so as to avoid the leakage during the working of the pump for a long time.

The 2BE4 liquid ring vacuum pump and compressor series is an upgrade to the proven 2BE3 modeland has been engineered to deliver improved perfomance, reliability, and efficiency over the previousmodels. Compared to previous models the 2BE4 offers efficiency improvements up to 8% and hasreduced maintenance requirements.

Based on the proven reliable flat sided liquid ring vacuum pump design the 2BE4 has a polyisoprenelined body, flexible inlet and discharge connections, and a large inspection port for improvedperfomance and reliability, With capacity ranging from 2,000 to 32,300 m%h, the 2BE4 is wellmatched to demanding environments like the paper, powver, mining, and chemical process industries.

Suction Capacity:1,200 to 19,000 ACFM (2.000 to 32.300 m3/h)Vacuum Range: to to l60 mbar abs.

Discharge Pressure Range: 2.5 bars abs

Differential Pressure: to l.5 barShaÃt Seals: $uffing box (standard)Mechanical Seals (single acting / double acting) on requestMaterials ofConstruction: Duetile iron, stainless steel, combination of both materials

2BE4 series products can be driven with many different sets, such as, the V-belt, synchronal motor,gear box etc. In order to save space, more than two or at most four sets of the 2BE4 series pumps canbe driven by one motor simultaneously.

To satisfy the customer's different ways of installation, both top and side inlet and outlet are opened andmachined, our standard pump material is cast iron, for special application, pump in stainless steelS8304, stainless steel $S3l6L, stainless steel $S32l, duplex stainless steel $S2205 and cast iron pumpwith stainless steel flow parts are available.

When set a middle wall in the casing, the pressure tolerance between the two sides is lower than 80kPaand the two parts can work in different vacuum status respectively, Thus, one pump can work well liketwo. Hereby the product operating flexibility is improved effectively.
