Technical Transformation Project of Dry Vacuum System in a Pharmaceutical Industry

In the drug extraction and concentration section of a pharmaceutical company workshop, a liquid ring pump was used to provide vacuum in the ethanol solvent recovery device of the multi-effect evaporator. Due to the low recovery rate of ethanol gas in this system, The consumption and waste of ethanol were increased in the extraction process; at the same time, in the process of ethanol condensation, a large amount of waste liquid will be formed, which increases the cost of waste water treatment.

The APUMP technical team upgraded the system for the solvent recovery section of the company: using a single-pole claw dry vacuum pump to replace the raw liquid ring pump, the system greatly improves the recovery rate of ethanol, and at the same time, there is no waste water during the working process,  reducing the operating cost of the equipment.

The characteristics of the single-pole claw dry vacuum pump:

 1. High efficiency, low power consumption;

 2. No emissions, pollution, and friendly to the environment;

 3. Low maintenance cost;

 4. High recovery rate.
