HIB--SZ series chemical anticorrosive ceramic water ring vacuum pump
People often encounter the transfer of chemical gases during use, which requires the introduction of a new concept of corrosion-resistant vacuum pumps. It uses ceramic as a special medium to make the over-current part, which truly meets the requirements of the usual "wear, acid, alkali and high temperature".
2BV series direct water ring vacuum pump
2BE type water ring type vacuum pump is a new generation of water ring type vacuum pump developed by our factory on the basis of the original SK type and 2BV type water ring type vacuum pump to meet the requirements of vacuum pump with water suction. It is advanced in design and novel in structure, and is suitable for a variety of more demanding and complex applications. It can pump media containing a large amount of water vapor and condensable gas. It is not easy to be dangerous when pumping flammable, explosive or toxic and corrosive gases, so it can be widely used in machinery, petroleum, chemical, electric power, pharmaceutical, Food, ceramics, sugar, printing and dyeing, metallurgy, plastics, tile, leather and other industries, especially suitable for plastic use, 2BA water ring vacuum pumps replace SZ, SK, 2SK-3, 2SK-6, 2S-185 , 2SK-230 and W reciprocating vacuum pumps.
The 2BV series water ring vacuum pump is suitable for pumping out gas and water vapor, and the water absorption pressure can reach 33mmbar absolute pressure (97% vacuum pump). When using transformer oil as working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum pump), which can completely replace the reciprocating vacuum pump. When the vacuum pump is working for a long time when the suction pressure is close to the ultimate vacuum, the cavitation protection tube should be connected to protect the pump. When used as a compressor, the pressure is up to 0.26 MPa (absolute pressure). As a new generation of energy-saving products, 2BV series water ring vacuum pump will completely replace the SK, 2SK, W, WY and WL series water ring vacuum pumps and reciprocating vacuum pumps with the same performance and many advantages.
SK series water ring vacuum pumps and compressors are vacuum pumps developed in the 1980s. The SK series is technically completely replaceable by the 2BV, 2BE series. The company does not recommend the use of SK series products.
