Dry Screw Vacuum Pump Boosts Efficiency for German Chemical Plant

Client: A specialty chemicals manufacturer based in Bavaria, Germany.
Industry: Fine Chemicals Production
Application: Solvent Recovery in a multi-stage distillation process.
Challenge: The client's existing oil-sealed pumps caused frequent contamination of recovered solvents, leading to product quality issues, costly reprocessing, and high maintenance costs due to oil degradation when handling condensable vapors.
Solution: After a technical evaluation, our engineers recommended two Kaien LGV-540 Water-Cooled Dry Screw Vacuum Pumps. The key decision factors were:

· Oil-Free Operation: Guaranteed no hydrocarbon contamination of the high-value solvents.
· Handling Condensable Vapors: Excellent performance in pumping large volumes of solvent vapors without pump damage.
· High Vacuum Performance: The ability to reach and maintain a stable vacuum below 5 Pa was critical for the distillation efficiency.
· Energy Efficiency: The variable pitch screw design offered lower power consumption compared to their old system.
  Results:
· Product Purity: Achieved a significant improvement in the purity of recovered solvents, eliminating reprocessing steps.
· Maintenance Reduction: Maintenance intervals were extended by over 300%, and costs for oil changes and filter replacements were eliminated.
· Energy Savings: Recorded a 15% reduction in energy consumption for the vacuum system.
· ROI: The client reported a full return on investment within 14 months through increased yield and reduced operational costs.
  Client Testimonial: "The switch to Kaien's screw vacuum pumps was a strategic move for our green chemistry goals. The reliability and cleanliness have exceeded our expectations." – Plant Operations Manager
