The application range and characteristics:
2BE3 series water ring vacuum pumps and compressors 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 2BE3 series products are designed for pumping various gases. They are widely used in many industries, such as, the paper, mine, power station, chemical etc.
2BE3 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 2BE3 series pumps can be driven by one motor simultaneously.
When set a middle wall in the casing, the pressure tolerance between the two sides is lower than 80kPa and the two parts can work in different vacuum status respectively. Thus one pump can work well like two. Hereby the product operating flexibility is improved effectively.
The main characteristics of 2BE3 series products:
· The tolerance, corrosive status, and the begrime situation can be easily observed by the big inspection port on both sides of the end-shield.
· The 2BE3 series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BE3 series pumps.
· 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.
· 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.
· The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE3 series pumps.
· The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material.
· 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.
· The unique design of setting the separator above the pump saves the space and decreases the noise efficiently.
· 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.
· 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.
