Laub/Hunt Packaging Systems: Precision, Performance, and Turnkey Excellence

Laub/Hunt Packaging Systems brings over 70 years of experience to the forefront of liquid filling innovation. Their commitment to high-quality engineering and personalized support continues to set industry standards.

High-Speed, High-Volume Fillers

Laub/Hunt’s rotary and in-line liquid filling machines are engineered to meet the pace of modern production. Available with anywhere from 4 to 120 filling heads, these systems can reach speeds of up to 1,000 containers per minute—perfect for fast-moving, high-output operations.

Tailored Filling Technologies

Designed to handle a broad spectrum of product types and container needs, Laub/Hunt offers:

  • Gravity, Pressure/Gravity, and Vacuum systems for products ranging from light juices to delicate or foamy liquids,
  • Pressure metering systems for viscous or thick liquids like lotions and gels.

This flexibility ensures accurate fills across diverse industries.

Superior Build & Sanitation

Every machine is constructed with stainless steel, promoting steel hygiene and durability. The design supports food-grade and chemical-resistant applications, including corrosive products like bleach. Advanced Clean-In-Place (CIP) capabilities and washdown-ready configurations reduce downtime and reinforce operational cleanliness.

Comprehensive Turnkey Solutions

Laub/Hunt goes beyond standalone fillers, offering end-to-end packaging line integration—from bottle unscramblers and cappers to case packers and centralized controls. Their support includes customer training, instructional videos, and full-function trial runs, ensuring seamless implementation from start to finish.

Unparalleled Engineering & Service Support

With a global support infrastructure, they provide:

  • Dedicated on-site start-up, commissioning, and operator training,
  • Responsive field service and technical maintenance,
  • Spare parts availability and system upgrades,
  • Machine rebuilding and optimization services to prolong lifecycle and performance.

MASSFlow and MAGFlow Filling Technologies

March 18, 2026
The primary differences between MASSFlow and MAGFlow filling technologies lie in the type of meter used, their accuracy, and the specific products they are engineered to handle. 1. Meter Technology and Accuracy ● MASSFlow: This technology utilizes Coriolis flowmeters (typically Endress+Hauser DosiMass or Promass F models). It is highly accurate, consistently delivering a fill accuracy of +/- 0.25% (+/- 1/4 of 1%). ● MAGFlow: This technology uses magnetic flowmeters (specifically Endress+Hauser DosiMag models). While some applications for specific chemicals list an accuracy of +/- 0.25%, the general specification for MAGFlow systems is often cited at +/- 0.5% (+/- 1/2 of 1%) throughout the fill range. 2. Product Suitability ● MASSFlow Applications: These systems are extremely versatile and can handle a vast range of viscosities. They are used for motor oils, shampoos, conditioners, solvent-based stains, polyurethanes, and food products like canola or soybean oil. They are even capable of filling heavy materials like asphalt at temperatures up to 350°F. ● MAGFlow Applications: MAGFlow is specifically designed for conductive liquids . It is the preferred technology for aqueous, foamy, and bleach-based household cleaners or car wash products. 3. Operational Requirements and Versatility ● MAGFlow Constraints: For maximum accuracy, MAGFlow requires liquids to be supplied at a constant density, pressure, and temperature . The product must also be free of entrained air or emulsified gases, which can vary the apparent density and affect the meter reading. ● MASSFlow Versatility: MASSFlow systems allow for individual head calibration via the HMI (Human Machine Interface) and can store pre-programmed "recipes" for over 100 different product/bottle combinations. They are best suited for filling volumes ranging from 0.5 to 128 oz. Both systems are often housed on similar frames (T304 or T316 Stainless Steel) and feature "No Bottle, No Fill" nozzle technology to prevent waste. Contact us for more information.
