Rotary Volumetric Filler – High‑Speed Fillers Accommodate a Wide Range of Containers and Products, from Water‑Thin to Heavy Syrups, Oils and Shampoos

July 24, 2025

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

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.
