Liquid Filling Machines — Piston, Gravity, Overflow, and Pump Systems

Who It's For
Food & Beverage
Water, juice, sauce, oil, vinegar, dairy, condiments — food-grade contact materials and hygienic design.
Cosmetics & Personal Care
Shampoo, lotion, cream, perfume, hand sanitizer — overflow fillers for consistent fill level in clear bottles.
Chemical & Cleaning
Detergent, disinfectant, industrial lubricant, pesticide — chemical-resistant materials and enclosed design.
Pharmaceutical
Bottles, vials, syringes — GMP-compliant systems with SUS316L contact parts and cleanroom-ready designs.
Suitable Products
Thin / low-viscosity
- Water
- Juice
- Vinegar
- Alcohol
- Cleaning agents
Medium viscosity
- Cooking oil
- Ketchup
- Salad dressing
- Honey
- Shampoo
High viscosity / paste
- Tomato paste
- Cream
- Ointment
- Adhesive
Foamy liquids
- Beer
- Carbonated beverages — special filling head required
Viscosity and foam level determine the optimal filling method. We recommend based on product data.
Packaging & Output Options
All stated ranges are configuration-dependent — we confirm based on your container, fill volume, and liquid type.
Available Configurations
Piston Filler
High accuracy (±0.5–1%), suitable for thick to thin liquids. Adjustable piston stroke for volume. Servo-driven for highest accuracy.
Gravity Filler
For thin, free-flowing liquids. Simple, low maintenance. Fill by weight or time.
Overflow Filler
Fills to a consistent level regardless of volume — ideal for cosmetics in clear bottles where appearance matters.
Peristaltic Pump Filler
For aggressive chemicals, pharmaceuticals, or very small volumes. No product contact with pump mechanism.
Flow Meter / Mass Flow Filler
Highly accurate volumetric filling for valuable liquids. Used in oil, spirits, and pharmaceutical applications.
Rotary Filling Machine
High-speed multi-head system for bottles. 50–300 bottles/min. Integrated with capper and labeler.
Pouch / Sachet Liquid Filler
For sauce sachets, ketchup, or liquid pouches. Piston or peristaltic pump.
Materials & Compliance
CE certified; SUS304/316L contact parts meet food or pharmaceutical standards; voltage/frequency configurable.
Key Decision Factors
Process Integration
This machine integrates into your broader production workflow at the filling stage. A typical integrated liquid line may include:
We design filling systems to integrate with your container format, capping method, and labeling system. Single machines or complete fill-cap-label lines.
Frequently Asked Questions
Flow meter or piston filling gives the best accuracy for oil. Overflow fillers are also used for oil in clear bottles where fill level appearance matters. We recommend flow meter filling for high-value oils where accuracy is critical.
A piston filler can handle a range of viscosities — from water-like to paste — by adjusting piston speed, valve timing, and nozzle size. For very wide viscosity range (water and thick paste on the same line), we usually recommend one machine per product type or a flexible piston filler with dedicated change parts.
This depends on machine type. Peristaltic pump fillers can do as little as 1–5ml. Piston fillers typically start at 5–10ml. Large industrial fillers can fill 10–20L containers. Tell us your target fill volume and container size.
Yes, but these require counter-pressure filling heads or bottom-up filling nozzles to minimize foam. This is a specialized configuration — please specify if you're filling carbonated or foamy products.
Yes. We supply complete fill-cap-label lines, including screw cappers, ROPP cappers, snap cappers, pressure-sensitive labelers, and sleeve labelers. These can be supplied as standalone machines or fully integrated lines.
Liquid name and approximate viscosity (e.g. "similar to water" or "similar to honey"), fill volume, container type and size, required output speed, country/voltage, and whether you need a standalone filler or full line.
Describe your liquid and container — we'll recommend the right filling system.
Piston, gravity, overflow, pump, or flow meter — our engineers select the filling method based on your product, accuracy requirement, and output target.
