1.single-stage vacuum pump-2SK
Introduction:
Model 2SK Liquid Ring Vacuum Pump characteristic its energy consumption little,the noise is low,besides canning smoke except the general gas,Too can release and suck steam,change major part material,can also release and breath in the inflammable and explosive and corrosivity gas.So the pump has already widely been applied to the vacuums craft in every profession and trade,such as light industry,chemical industry, food, electric power, medicine,etc. while dealing with.
Main features:
1: Comparison of single stage water ring vacuum pump, high vacuum degree, such as large area in the high vacuum pumping speed characteristics;
2: Compact structure, easy maintenance ;
3: The wide range of applications, can smoke in addition to water vapor, inflammable, explosive, containing a small amount of dust, all kinds of gas containing a small amount of liquid ;
4; Main water as working medium, low maintenance cost;
5: Can work under relatively harsh environment .

2. Water ring vacuum pumps of 2BE
2BE series water ring vacuum pumps and compressors is the basis of years of scientific research and production experience combined with international advanced technology developed energy-efficient products, usually used for suction without solid particles, insoluble in water, non-corrosive the nature of the gas, in order to form a vacuum in the airtight container and pressure. By changing the structural material, the working fluid can also be used for pumping corrosive gases or corrosive liquids. Widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, electrical appliances, coal washing, beneficiation, fertilizer and other industries.
3. Water ring vacuum pumps of 2BV
2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump.
When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure, the larger of the power of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor.
2BV2-Ex,2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.
2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.
2BV series products possess the characteristics as bellow
- The close-coupled design is convenient to install and can save space.
- The standard seals are all used the John Crane mechanical seals.
- 2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.
- Stainless steel impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.
- The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the pump.
- The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.
- The bearings are all used the imported products with brand name of NTN or NSK.
