  • 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.​

Precision Filling with Laub/Hunt Pressure Metering Fillers

September 2, 2025
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? Contact Laub/Hunt today to learn how our Pressure Metering Fillers can improve your efficiency and deliver unmatched accuracy in your production process.

Information about Mag Flow (Magnetic Flow) Rotary Fillers

August 29, 2025
Information about Mag Flow (Magnetic Flow) Rotary Fillers Mag Flow (Magnetic Flow) Rotary Fillers are a type of filling machine commonly used in the beverage industry for filling liquid products into bottles or containers. These fillers utilize magnetic flow meter technology to achieve precise and accurate filling. Here's an overview of Mag Flow Rotary Fillers: Magnetic Flow Meter Technology: Principle: Mag Flow Fillers rely on the principles of electromagnetic flow measurement. When a conductive liquid flows through a magnetic field, it induces a voltage that is directly proportional to the flow rate. Accuracy: This technology provides high accuracy in measuring the flow rate of liquids, making it suitable for applications where precise filling volumes are crucial. Rotary Filling Mechanism: Design: Mag Flow Rotary Fillers are equipped with a rotary mechanism that allows bottles to move through the filling station in a circular or rotary fashion. Advantages: The rotary design enables high-speed filling operations, making these fillers suitable for high-throughput production lines. Bottle Handling System: Conveyor System: Bottles are typically transported on a conveyor system that moves them through different stations, including filling and capping. Indexing: The rotary mechanism indexes the bottles through each station, ensuring that they are precisely positioned for filling. Filling Process: Precision Filling: Mag Flow technology ensures accurate and repeatable filling volumes. The flow meter measures the liquid flow rate, and the filling nozzles dispense the exact amount of product into each bottle. Clean Filling: These fillers are suitable for filling a variety of liquid products, including beverages, and are often used in applications where cleanliness and hygiene are essential. Capping Station: Integration: Mag Flow Rotary Fillers are often part of a larger packaging line that includes a capping station. After filling, bottles move to the capping station where caps are applied and secured. Control System: Automation: These fillers are typically equipped with an automated control system that oversees the filling process. This system ensures that the correct fill volume is maintained, and it may interface with a central control system for the entire packaging line. Cleaning and Maintenance: CIP (Clean-in-Place): Mag Flow Rotary Fillers are designed to facilitate cleaning between product changeovers. Some models may have integrated Clean-in-Place systems to streamline the cleaning process. Versatility: Product Range: Mag Flow Rotary Fillers are versatile and can handle a wide range of liquid products, including carbonated and non-carbonated beverages, juices, water, and more. These fillers are a popular choice in industries where precise and high-speed filling is required, and the use of magnetic flow meter technology enhances their accuracy and reliability in achieving consistent fill volumes.
