A liquid filling machine is the heart of any bottling line, designed to accurately dispense a precise amount of product into containers. The choice of filling technology—Piston, Overflow, Flowmeter, Peristaltic—is critical and depends entirely on the product's characteristics, such as viscosity, foaming tendency, and required accuracy.

Choosing the right liquid filler is key to efficiency and product quality. Piston fillers are versatile workhorses, ideal for both thin liquids and thick pastes like creams and sauces. Overflow fillers are perfect for achieving a consistent cosmetic fill level in transparent bottles, regardless of minor volume variations in the containers. Flowmeter fillers (magnetic or mass) offer high precision and are excellent for a wide range of conductive or non-conductive liquids. Peristaltic fillers provide the ultimate hygienic solution for pharmaceutical and biotech applications, as the product only touches a disposable tube. We analyze your product and process to recommend and build the optimal filling solution.

FAQ - English

Q1: I have a clear bottle. Which filling machine ensures all bottles on the shelf look equally full?
A1: An Overflow Filler is the perfect choice. It fills to a specific level on the neck of the bottle, not by a specific volume. This creates a visually perfect, uniform appearance on the retail shelf, even if the internal volume of the bottles varies slightly.
Q2: I fill a very expensive product. What technology gives the highest accuracy to avoid giveaway?
A2: For ultimate accuracy, either a Mass Flowmeter filler or a Piston Filler integrated with a weigh scale (Net Weight filling) are the best options. They are not affected by temperature or density changes and ensure you dispense the exact amount of product every time.
Q3: How do you handle very thick products like peanut butter or heavy creams?
A3: A Piston Filler is the ideal technology for high-viscosity products. We use a large-diameter cylinder and heavy-duty pneumatic or servo-driven piston to provide the force needed to push the thick product cleanly and accurately into the container. Often, this is paired with a heated hopper to reduce viscosity.
Q4: We fill multiple products and bottle sizes. How long does a changeover take?
A4: Our machines are designed for quick changeovers. Adjusting guide rails, nozzle heights, and fill volumes is done via digital readouts or recipes on the HMI. Swapping contact parts for cleaning is often tool-less. A typical changeover can take anywhere from 15 to 40 minutes depending on the complexity.
Q5: Can your fillers handle flammable or corrosive liquids?
A5: Yes. For such applications, we build "explosion-proof" or intrinsically safe machines. This involves using pneumatic logic instead of electronics, specialized ATEX-rated motors, and ensuring all wetted parts are made from chemically resistant materials like Kynar (PVDF) or Teflon.
