Vacuum Distillation Pump

The vacuum distillation pump plays a crucial role in the thermal separation process. Its main function is to convey the more volatile medium at the column head, facilitating further separation through pressure change. Additionally, the vacuum pump helps remove non-condensable water and light solvents from the system, enabling the extraction of target compounds from the reaction mixture. Vacuum distillation is particularly useful for handling compounds with high boiling points, heat sensitivity, and explosiveness, such as active pharmaceutical ingredients. With its ability to lower boiling points under vacuum, this method provides an ideal solution for efficient and safe separation processes. As a leader in vacuum pump production, we are committed to providing reliable and high-quality equipment for various industrial applications.

Screw vacuum pump advantages for the vacuum distillation:

  • High vacuum: High vacuum levels are achieved through the use of screw vacuum pumps, which provide smooth and efficient processes in the chemical industry. Screw vacuum pumps offer a versatile solution in the field of distillation by providing the capability to form a separate vacuum system or be used as a backing pump in combination with Roots pumps. This unique combination allows for the achievement of a higher vacuum level while maintaining a large pumping speed. By using screw vacuum pumps, not only can stable and optimal conditions be provided for the operation of Roots vacuum pumps, but also the need for multiple Roots pumps can be reduced. In comparison to commonly used liquid ring pumps as backing pumps in the chemical industry, screw vacuum pumps offer adjustable configurations, such as transitioning from a two-stage Roots + liquid ring setup. This adaptability makes screw vacuum pumps an efficient choice for distillation processes, offering improved performance and productivity.
  • Good stability: The screw vacuum pump has a straightforward design, is reliable, and does not experience issues. The chemical distillation process can be maintained without fluctuations in vacuum performance due to the stability of vacuum performance.
  • Energy-saving and environmental protection: the energy consumption of screw vacuum pump is low, the main process has no oil, water and other media involved, and it is a kind of dry vacuum pump, which will not pollute the environment, thus meeting the energy-saving and environmental protection requirements of the modern chemical industry.

Roots vacuum pump(Roots vacuum booster) advantages for the vacuum distillation:

  • It has a high pumping speed and a low pumping time, which enables it to rapidly and effectively reduce the system pressure during distillation, achieving a high pumping speed and a low pumping time.
  • The low noise and minimal vibration of the Roots vacuum pump allow for the quiet and stable operation of distillation equipment.
  • Roots vacuum pumps have low maintenance costs and long service life, and can maintain stable performance during long-term operation, thus saving costs and maintenance time for users.
  • The Roots pump possesses a high ultimate vacuum and can maintain a large pumping speed at a high vacuum, enabling it to perform some distillation applications requiring high vacuum and high flow rate.
  • Roots vacuum pumps can enhance the efficiency of degassing and dehydrating during distillation, as they provide steady vacuum levels. The Roots vacuum pump is capable of extracting a significant amount of gas in a brief period of time and generating an instantaneous vacuum process. Roots vacuum pumps can withstand certain gas flux impacts and are suitable for processing a variety of gas components, allowing for greater flexibility in distillation operation
