Molecular Distillation Gear Metering Pump
Molecular distillation gear metering pump
The molecular distillation gear metering pump is a high-precision positive displacement pump specifically designed for demanding fine chemical applications involving high vacuum and high temperatures-such as short-path distillation, molecular distillation, and thin-film evaporation. Its primary function is to facilitate the continuous, stable, and precise transfer of materials into and out of distillation systems.
It is particularly well-suited for handling heat-sensitive and high-viscosity substances-including Vitamins A and E, oils and fats, fragrances, higher alcohols, and pharmaceutical intermediates-and serves as a critical metering component within molecular distillation units.
Application of the molecular distillation gear metering pump
-
1. Molecular Distillation Unit Feed Metering Pump
2. Distillation System Reflux Pump and Light Component Discharge Pump
3. Discharge and Transfer Pump for Heavy Components and High-Viscosity Bottoms
4. Purification Processes for Vitamin A/E, Fish Oil, Natural Flavorings, Sterols, Dimer Acids, etc.
5. Continuous Proportioning and Quantitative Transfer under High-Temperature and High-Vacuum Conditions
Advantages of molecular distillation gear metering pump
-
1. Molecular distillation requires a high - vacuum environment, and dedicated pumps can meet this requirement, ensuring the vacuum degree of the system during the distillation process. This provides a favorable environment for molecular distillation, allowing light molecules to smoothly fly from the evaporation surface to the condensation surface, achieving efficient separation.
-
2. The circular - arc rotors of molecular distillation pumps have a very low relative sliding speed, operate smoothly, have less wear, no oil - trapping phenomenon, and low noise. Magnetic gear pumps and other pumps, which use magnetic drive, can also reduce vibration and noise, have little impact on the process, and are conducive to maintaining a stable distillation process and ensuring product quality.
