DTM Purefil Liquid Fillers
Clean & Accurate Filling on Your Line, Every Time
DTM Packaging’s Purefil Liquid Filler line combines precision, flexibility, and sanitary design to deliver consistent, high-quality in-line flow meter liquid filling performance. Designed for accuracy-driven, multi-product production lines, Purefil systems offer unmatched cleanliness, repeatability, and easy maintenance — all within a robust, ergonomic design.
Available in three configurations — the Purefil 1500, Purefil 2000, and Purefil 2500 — this series accommodates everything from small-batch runs to high-speed continuous production, ensuring every bottle, jar, or container is filled perfectly, every time.
DTM’s Purefil Liquid Filler’s sanitary design and built-in Clean-in-Place (CIP) functionality streamline cleaning between batches, minimizing downtime and reducing contamination risk.
From personal care and OTC pharmaceuticals to food, beverage, and specialty chemicals, the Purefil line represents a premium, U.S.-made solution for reliable filling operations.
How It Works
The Purefil uses flow meter-based filling technology — either Mass or Magnetic Flow Meters — to achieve exceptional accuracy, averaging ±0.25% standard deviation.
- The Purefil 1500 operates as an indexing system — bottles advance via a servo-controlled conveyor, stop under the fill heads, and are filled simultaneously. Once complete, the filled set exits and the next group indexes in.
- The Purefil 2000 and 2500 models feature a walking beam system, where filling heads move with the containers, allowing continuous filling without pauses. This delivers faster throughput, up to 300 bottles per minute, with no “gaps” in production.
In all models, servo-controlled nozzle bars, height adjustments, and programmable recipes ensure consistent operation and minimal setup time between product changes.
Every unit is constructed with 316L stainless steel contact parts and FDA-compliant sanitary fittings, eliminating potential contamination points across the product path.
