Innovative Vacuum Solutions for Beer Bottling: Sustainability, Efficiency, and Quality


In today’s brewing industry, producers face the challenge of reducing operational costs, minimizing environmental impact, and improving product quality. A key aspect of this process is the vacuum system used for beer bottling. Traditional liquid ring pumps (LRPs) are gradually being replaced by modern dry screw vacuum pumps like Leybold’s DRYVAC, which offer significant advantages in sustainability, energy efficiency, and product quality.

Challenges of Traditional Systems
LRPs have long been the standard in beer bottling due to their tolerance for liquid and foam ingress. However, they come with major drawbacks:

  • High water consumption: LRPs require a constant water flow, leading to significant costs and wastewater disposal issues.

  • Low energy efficiency: These pumps consume excessive electricity.

  • Limited vacuum performance: Maximum pressure is capped at 33 mbar under optimal conditions.

  • Cavitation risk: Cavitation can damage pumps and cause downtime.

  • High maintenance costs: Frequent servicing and part replacements increase total ownership costs.

The Solution: DRYVAC Dry Screw Vacuum Pumps
Leybold’s innovative Beer Bottling Vacuum System (BBVS) features DRYVAC DV 650 and 800 FP-r pumps, designed for washdown environments and offering unique benefits:

  1. Sustainability and Eco-Friendliness

    • Up to 80% water savings: No water required, eliminating contaminated wastewater.

    • Energy efficiency: 20% lower electricity consumption vs. traditional pumps.

    • No cavitation risk: Dry screw technology ensures reliable operation.

  2. Enhanced Product Quality

    • Reduced TPO (Total Package Oxygen): Deeper vacuum (down to 0.005 mbar) and higher flow rates lower oxygen levels, extending shelf life and improving taste.

    • Process stability: Consistent vacuum pressure ensures superior bottling quality.

  3. Durability and Low Maintenance

    • Reduced operating costs: No sealing fluids and minimal wear parts cut maintenance expenses.

    • Washdown-ready: Epoxy coating, stainless steel construction, and internal flushing capabilities meet food industry standards.

    • Robust performance: Handles liquid and foam ingress with ease.

Case Study: Customer Results
Implementation at a major brewing company delivered impressive outcomes:

  • TPO reduction: Oxygen levels dropped by 7–35%, depending on beer type.

  • Resource savings: 80% less water and 20% less energy consumed.

  • Cost savings: Total ownership costs were €124,539.45 lower over 4 years vs. LRPs.
