2BA series oil (liquid) ring vacuum pump and compressorDetailed product description：

Scope of use of 2BA series oil (liquid) ring vacuum pumps and compressors

The 2BA series oil ring vacuum pump is based on the 2BV series water ring vacuum pump, which changes the working fluid from water to transformer oil. The ultimate vacuum degree of the water ring vacuum pump is significantly increased due to the low saturation vapor pressure of the oil, reaching an absolute pressure below 6.7 mbar, or even 1.3 mbar. However, the water ring vacuum pump can only reach an absolute pressure of 33 mbar due to the high saturation vapor pressure of water. When extracting gases with high pollution and in certain special working situations, the working fluid of the 2BA series oil ring vacuum pump can also use water or other liquids. As the pump is a closed-loop system, it greatly reduces environmental pollution, and its ultimate vacuum degree is determined by the saturated vapor pressure of the working fluid.

Oil ring vacuum pumps are widely used for evaporation crystallization, drying and filtration in refining, pigments, plastics, soap, food, sugar production, pharmaceuticals and other fields; Concrete work in the field of construction; Vacuum degassing and other processes in the metallurgical industry. Due to its compact structure, low maintenance, reliable operation, and high efficiency, it can replace reciprocating vacuum pumps such as W, WY, WL in many occasions.
