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.​

At Laub\Hunt, we understand that modern production lines demand high-speed volumetric filling coupled with industry-leading accuracy , versatility , and robust engineering . Our Rotary Volumetric Filler , also known as the Posifiller , delivers just that—precise, high-output filling for countless container and product types. High Speed, High Throughput Built for demanding operations, the Rotary Volumetric Filler runs at up to 600 containers per minute (cpm) while offering fill accuracy of ±¼ % , minimizing product waste and inconsistencies. Its rotary design supports speeds up to 600 cpm and accommodates up to 120 nozzles on large-frame machines. Wide Range Compatibility: From Thin to Thick This filler is engineered to handle a broad viscosity range—from water-thin liquids like water or light juices, to heavier syrups, oils, detergents and shampoos . Its enclosed filling system ensures product integrity and precision across the spectrum. Containers from 1 oz to 5 gallon volumes are accommodated with minimal changeover time and tool-free adjustments. Precision Mechanics at Work At the heart of the Posifiller is a unique enclosed piston‑cylinder assembly. A free-floating piston delivers exact volumes by displacement between positive stops, controlled by an adjustable volume rod. The four‑way spool valve maintains balanced pressure and enables accurate two-phase pistoning for each fill. These design features deliver consistent fill volumes and ensure extremely low deviation—critical in regulated or costly product environments. Watertight Design for Hygiene and Efficiency Sanitary operation is built into the design. No ambient air enters the system—from surge tank to nozzle—thanks to the closed construction of the Posifiller. This reduces contamination risk and maintains product quality. The system is also washdown-capable , with all drive motors placed atop the unit; and CIP (clean-in-place) product flush systems are standard or optionally automated. Engineered for Flexibility and Ease Designed for minimal downtime, the machine enables on‑the‑fly volume adjustment across stations via a motorized volume plate—ideal for format changes or multiple SKUs. Starwheels and nozzle assemblies allow tool‑free starwheel changes , making size changeovers fast and operator‑friendly. Industry‑Grade Features Stainless steel construction (T304 standard, optional T316 or specialty materials for caustic applications) Individually adjustable cylinders and nozzles Safety-interlocked guarding and AC drive with clutch Premium options including explosion-proof (NEMA‑4X or NEMA‑7) electrics and automatic CIP Conveyor lengths up to 10 ft with precision Delrin chain guides Why Choose Laub\Hunt’s Rotary Volumetric Filler? With unmatched precision, high-speed throughput, and broad product/container adaptability, Laub\Hunt’s Posifiller is trusted in food & beverage, personal care, chemicals, household products, and more.
