Types of Bottling Systems: Choosing the Right Solution for Your Production Line

March 1, 2025

Selecting the appropriate bottle filler is crucial for optimizing your production line's efficiency and ensuring product quality. At Laub/Hunt, we offer four distinct types of bottle fillers, each designed to meet specific production needs.​

Rotary Mag-Flow Filler

Our Rotary Mag-Flow Filler utilizes electromagnetic flow meter technology to achieve precise and accurate filling. This system is ideal for the beverage industry, ensuring consistent fill volumes for products like juices, water, and other non-carbonated drinks. The rotary design enables high-speed operations, making it suitable for large-scale production lines. ​

Key Features:

  • High Precision: Magnetic flow meters provide accurate measurement of liquid flow rates.​
  • High-Speed Operation: Rotary mechanism allows for efficient filling at high speeds.​
  • Versatility: Suitable for a wide range of liquid products.​

Pressure Metering Filler

Designed for high-viscosity and semi-liquid products, the Pressure Metering Filler employs a positive displacement pump to maintain consistent pressure, ensuring uniform fills. This filler is perfect for products like sauces, creams, and other thick substances. Its sanitary design includes stainless steel construction and Clean-In-Place (CIP) systems, facilitating easy cleaning and maintenance. ​

Key Features:

  • Accurate Filling: Achieves fill accuracies of +/- 0.5%.​
  • Sanitary Design: Stainless steel construction suitable for food and cosmetic products.​
  • Versatility: Handles a wide range of high-viscosity products.​

Rotary Volumetric Filler

The Rotary Volumetric Filler operates on a positive displacement principle, ensuring each container receives an exact volume of product. This system is beneficial for products where precise volume is critical, such as in pharmaceuticals or specialty chemicals. The enclosed design prevents air from entering the system, maintaining product integrity and reducing oxidation.​l

Key Features:

  • Precision: Delivers exact volumes for each fill.​
  • Enclosed System: Prevents contamination and maintains product quality.​
  • Adaptability: Suitable for various liquid viscosities.​

Rotary Liquid Filler

Our Rotary Liquid Filler offers multiple filling methods, including gravity, pressure, and vacuum systems, to accommodate different product characteristics. This flexibility makes it ideal for a diverse range of products, from thin liquids like water to more viscous substances. The machine's design ensures high-speed filling with fill accuracy of +/- 1/16 inch, enhancing both efficiency and precision. ​

Key Features:

  • Multiple Filling Methods: Customizable to product-specific requirements.​
  • High-Speed Filling: Capable of speeds up to 1,000 containers per minute.​
  • Precision: Ensures consistent fill levels across all containers.​

Choosing the right bottle filler depends on factors such as product viscosity, desired fill speed, and specific industry requirements. At Laub/Hunt, we are committed to providing tailored solutions that meet your unique production needs.​

Laub/Hunt Looks Ahead: Innovation and Growth After a Successful 2025 PACK Event in Las Vegas After a standout showing at the Pack Event trade show in Las Vegas in September 2025, Laub/Hunt Packaging Systems is poised to enter an exciting new chapter of growth, innovation, and industry leadership. The buzz generated at our booth—where we showcased multiple types of bottle filling setups—has opened new doors, galvanized partnerships, and sharpened our vision for the future. At the Las Vegas event, attendees got a firsthand look at how Laub/Hunt tackles different filling challenges: from rotary volumetric and rotary liquid fillers , to pressure metering systems , and mag-flow electromagnetic fillers . Our flexible displays allowed visitors to see side-by-side comparisons of fill accuracy, speed, and hygiene features. That level of transparency and capability put the power in the hands of prospects to envision our equipment integrated into their production lines. Looking ahead, the future for Laub/Hunt hinges on several pillars: 1. Expanding Modular & Custom Solutions We know that no two production lines are identical. Some clients need high-speed rotary fillers, others need gentle bottom-up filling for foamy or delicate products, still others require viscosity-handling systems. Laub/Hunt is doubling down on modular designs, which allow upgrades or swapping of modules (e.g. nozzles, pumps, control systems) without needing to replace the entire machine. Customization—whether for unique bottle shapes, unusual liquids, or strict hygiene standards—will remain central to how we serve new customers. 2. Smarter Machines, Predictive Maintenance & AI We are actively investing in sensor integration, IoT connectivity, and machine-learning models to predict wear, flag performance degradation, and schedule maintenance before issues arise. Future Laub/Hunt machines will better communicate with upstream/downstream equipment, reducing downtime and boosting throughput. 3. Global Reach, Local Support From our base in Norwalk, CA, Laub/Hunt has manufactured liquid fillers for over 75 years. As we expand, the next phase is to strengthen regional service centers, spare parts networks, and local technical teams. That way, whether a beverage company in Europe or a cosmetics firm in Asia is deploying our rotary or pressure metering fillers, they’ll experience responsive support and faster turnarounds. 4. Vertical Market Focus & Industry Compliance As clients in food & beverage, personal care, household chemicals, and pharmaceutical industries grow more stringent in hygiene, regulatory, and sustainability demands, Laub/Hunt will double efforts in sanitary design (CIP, washdown compatibility), environmental efficiency, and compliance certifications. Our bottle filling machines will continue evolving to meet these vertical market needs. 5. Education, Training & Partnership We plan to host more webinars, interactive demos, and on-site training for customers, ensuring their operators can get optimal performance out of their equipment. Our Field Service and Technical Support teams will play a bigger role in post-sale success. Inspired by what you saw at the tradeshow? Let’s bring that momentum into your line. Explore our full line of rotary fillers , mag-flow filling systems , pressure metering machines , and Rotary Liquid bottle filling solutions .

At Laub/Hunt, we specialize in Pressure Metering Fillers designed for high-viscosity foods and semi-liquid products. These systems are built to handle challenging applications while delivering precise, consistent fills every time. The heart of the Pressure Metering system lies in its innovative filling head. This head is made of three plates carefully engineered to work together: The top two plates remain stationary to stabilize the flow. The bottom plate rotates , controlling the product’s movement and ensuring accurate portioning. This unique design allows for efficient filling of products that are too thick or uneven in texture for standard filling systems. From sauces and creams to chunky spreads and semi-liquid foods, our Pressure Metering Fillers are built to keep production lines running smoothly without sacrificing quality. Manufacturers trust Laub/Hunt for equipment that is durable, easy to maintain, and adaptable to a variety of product types. By combining precision engineering with robust construction, our fillers offer long-term reliability in even the most demanding environments. Looking to upgrade your filling line?
