Oil sealed rotary vane vacuum pumps play a vital role in the vacuum food packaging industry, offering the performance and reliability required to extend shelf life, preserve freshness, and ensure food safety.

In vacuum food packaging, efficiency, hygiene, and reliability are crucial. Among the most trusted technologies that enable these standards are Leybold Oil Sealed Rotary Vane Vacuum Pumps. These high-performance pumps are essential for removing air and moisture from packaging environments. By doing so, they extend the shelf life of food products while preserving their quality, flavor, and safety.

Leybold’s rotary vane pumps maintain consistent vacuum levels, which are critical in food packaging lines that require air-tight sealing. They quickly extract air from food containers—whether for meats, dairy, vegetables, or ready-to-eat meals—helping to create an oxygen-free environment. This environment significantly slows microbial growth and oxidation processes.

A significant advantage of Leybold’s oil-sealed models is their exceptional durability and ability to operate continuously, even in the most demanding industrial environments. Their compact design, low vibration, and quiet performance make them ideal for integration into automated packaging systems. Additionally, Leybold pumps feature robust oil circulation systems, ensuring effective sealing and cooling. Leybold’s vacuum pump contributes to lower maintenance needs and a longer operational life.

Food packaging requires strict adherence to hygiene and safety standards. Leybold pumps support clean operations by using high-grade materials and precision sealing to minimize contamination risks. Their compatibility with food-safe lubricants and efficient filtration systems makes them a reliable choice for food processors aiming to comply with international food safety regulations.

How Oil-Sealed Rotary Vane Pumps Work in Food Packaging

These pumps function by removing air from packaging, creating a vacuum that inhibits the growth of spoilage organisms and slows oxidation. This process helps keep food fresh for longer periods.

The oil in the pump serves several functions: it lubricates moving parts, seals internal chambers to achieve high vacuum levels, and dissipates heat generated during compression.

Their ability to maintain a consistent, deep vacuum ensures proper sealing of every package, which is vital for food safety and quality.

Why Oil-Sealed Rotary Vane Pumps Are Preferred in Food Packaging

• High Vacuum Performance: Oil-sealed rotary vane pumps achieve the deep vacuum levels (typically between 100–300 mbar) needed for effective food packaging and modified atmosphere packaging (MAP).
• Reliability and Consistency: These pumps deliver steady, reliable vacuum performance, which is crucial for automated packaging lines where consistency is paramount to maintaining product quality.
• Cost-Effectiveness: Oil-sealed rotary vane pumps are robust, durable, and relatively inexpensive to maintain compared to other vacuum technologies.
• Long Service Life: The oil creates a barrier that reduces wear on internal components, thus extending the pump’s lifespan.

What to Consider When Using Oil-Sealed Rotary Vane Pumps

• Clean Air Requirement: Food packaging environments typically maintain clean air, which minimizes the risk of contaminants entering the pump and causing oil degradation or clogging—a challenge in other applications.
• Maintenance: These pumps require regular oil changes and filter replacements, but their simple design makes maintenance cost-effective and straightforward.
• Limitations: Oil-sealed rotary vane pumps are not ideal for processes with high moisture or particulate loads, as these could emulsify the oil or cause contamination. However, in food packaging, where air quality is controlled, this is rarely an issue.

Applications in the Food Industry

• Vacuum Sealing: Removes air from packages to prevent spoilage and extend shelf life.
• Modified Atmosphere Packaging (MAP): creates a controlled environment inside the package to enhance product preservation.
• Thermoforming and Blister Packaging: Forms packaging materials around food products using a vacuum.
• Bottling and Canning: Ensures proper sealing and prevents contamination by removing excess air.
