Reducing Waste with Precision Bottle Filling Systems

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?

Precision by Design The Rotary Liquid Filler achieves fill accuracy of ±1/16" (less than 2 mm), ensuring each container meets strict quality standards. Nozzles insert under gentle control during filling to avoid splashing or aeration, while laminar-flow designs reduce sudden air entrapment. Tailored Filling Technologies Laub\Hunt offers a variety of fill systems to match product characteristics: Gravity fills for water-thin products Balanced pressure for heavier oils and syrups Gravity/vacuum or balanced-vacuum for glass containers or foamy products Each system is finely tuned to deliver consistent filling across diverse product types. Built for High Output and Sanitation Capable of up to 1000 cpm , this filler is suited for high-demand lines. Washdown-capable design, top-mounted drive motors, and CIP flush systems (manual or automatic) support fast, hygienic changeovers. Construction & Operational Excellence Stainless steel frame (T304 standard, up to T316L for pharmaceutical or food-grade) Optional titanium or PVC-lined nozzles for corrosive liquids such as bleach Tool-free changeover for starwheels, centering guides and rails Precision infeed/discharge starwheel control for bottle alignment and minimal product spillage. Versatility Across Containers and Products The Rotary Liquid Filler handles containers from ½ oz up to 5 gallon (standard up to 6.5″ diameter × 12″ height, with special machines up to 11″ × 19″), compatible with glass, plastic, metal or fiber formats. With speeds up to 1000 cpm and options up to 120 filling heads, volume and format agility is assured.
