In the pharmaceutical, chemical, and petrochemical industries, vacuum distillation serves as the core method for separating high-boiling-point and heat-sensitive substances. Typically, for every 100 mbar reduction in vacuum pressure achieved by the pump, the solvent's boiling point decreases by approximately 8°C, directly impacting production efficiency and energy consumption levels. However, the 2BV series liquid ring vacuum pump, featuring isothermal compression, mechanical seals, and zero-leakage operation, has become one of the preferred vacuum solutions for chemical distillation units. The device also features a flexible exhaust valve that automatically adjusts the compression endpoint. Vacuum fluctuations remain within ±3 mbar year-round, eliminating weather-related distillation time variations and significantly boosting production efficiency and output. 2BV series vacuum pump achieves an ultimate vacuum of 33 mbar, enabling solvents to boil at lower temperatures. This instantly reduces reboiler steam consumption by 15-25% while simultaneously minimizing side reactions such as high-temperature cracking and polymerization. Furthermore, the pump employs a double-ended mechanical seal with leakage levels below 3 drops per hour. When equipped with an optional condenser, the resulting exhaust gas concentration can fall below international standards, thereby enhancing production environment protection.
To enable direct passage of condensate, this pump features a large-channel drainage design that expels both water and gas simultaneously. Consequently, it can also transport liquids similar to solvents like ethanol, allowing direct reuse after condensation and boosting solvent recovery rates by 8-12%. The 2BV series vacuum pump also employs isothermal compression. In other words, the water ring pump's compression process is nearly isothermal, preventing sudden temperature spikes in the gas. This enables the use of water as the sealing fluid to extract flammable, explosive, dust-laden, or water-containing mixed gases. It also meets the transportation requirements for organic vapors and acidic gases commonly encountered in chemical operations, eliminating the need for additional drying. 2BV series horizontal vacuum pumps, characterized by high vacuum levels, high operational efficiency, and stable delivery, can assist chemical distillation processes by lowering temperatures, conserving steam, reducing emissions, and enhancing recovery. This capability helps minimize production costs, thereby improving economic efficiency.
