Liquid Filling Machine | Beverage, Chemical & Oil Filling Machine Supplier

Yundu is a premier Chinese manufacturer of liquid filling machines, with over 20 years of experience serving industries like cosmetics, food & beverage, pharmaceuticals, and chemicals. Our liquid filling machines – from simple tabletop fillers to automated production lines – deliver consistent, high-quality filling while boosting efficiency.

These systems automatically dispense liquids (from water-thin fluids to viscous sauces) into bottles, jars, or pouches, reducing waste and contamination by using features like no-drip nozzles and precise volume control. In short, Yundu machines are designed to handle everything from beverage filling machine lines to sauce filling machines and chemical filling machines, tailored to each product’s needs.

Industry Applications: Food, Beverage, Chemical, Pharma, Personal Care

Yundu liquid fillers serve a wide range of sectors. We support the food and beverage industry with machines for products like water, juices, sauces, oils, and condiments.

For example, high-speed rotary and follow-type filling machines (with 2, 4, or 6 heads) can fill hundreds of bottles per minute on a conveyor line. In the pharmaceutical and health supplement industries, our fillers handle syrups, solutions, and lab reagents with hygienic stainless-steel design. In daily chemical and personal care, machines fill items like shampoo, lotion, and cleaning detergents. Yundu has become a go-to supplier for food, pharmaceutical, and chemical companies thanks to our R&D expertise and custom solutions.

Across these industries, Yundu liquid filling machines reliably maintain uniform fill volumes and prevent product waste. For example, our equipment is designed to comply with strict quality standards (e.g. GMP), ensuring that everything from edible oil filling machines to paint filling machines meets customer specifications. Whether it’s a standard oil filling machine for cooking oil or a specialized chemical filler for corrosive liquids, Yundu’s equipment is tailored for the application and backed by global after-sales support.

Machine Types: Linear, Follow-Type, Rotary and 3-in-1 Systems

Yundu offers all mainstream filler configurations. Linear (Inline) Filling Machines mount multiple fill heads along a conveyor. Bottles move in sequence and stop briefly at each fill station. These inline machines can have from two up to eight or more heads, fitting small to medium production needs. They are cost-effective, scalable, and easy to maintain.

In contrast, Rotary Filling Machines use a circular turntable: bottles rotate under filling nozzles and are filled continuously without stopping the in/out conveyors. Rotary systems can reach very high speeds (20–50 heads filling simultaneously) and are ideal for large beverage runs or carbonated drinks where throughput is critical.

Another popular style is the follow-type (tracking) filling machine. These combine aspects of inline and rotary: bottles are clasped and follow a linear path under a moving multi-head gantry. We offer double-head, 4-head, and 6-head high-speed follow machines suited for detergents, beverages, and more.

For beverages like water and wine, Yundu also provides “3-in-1” washing-filling-capping machines. These integrated systems automatically rinse (wash) bottles, then fill and cap them in one compact unit. Such machines save floor space and boost efficiency. (For instance, our mineral water line handles thousands of bottles per hour by combining conveyors, rinse sprays, filling valves, and cap feeders.) In summary, Yundu’s range covers liquid filling production line solutions from basic table-top fillers to full automated lines.

Filling Modes and Technologies

Yundu machines use various filling principles to handle different liquids. Key modes include:

• Negative-Pressure (Vacuum) Filling:Ideal for glass bottles and foamy products. The filling head creates a vacuum that draws liquid in, preventing drips and foam overflow. This mode is common for carbonated or high-foam beverages. For example, a vacuum filler uses a centrifugal pump and a special filling head that “sucks back” foam so bottles fill cleanly.
• Weighing (Gravimetric) Filling:Used for large-volume or heavy-duty liquids (typically 5–20+ liters). These systems fill to a set weight, which is ideal for chemicals, paints, oils, and other high-volume products. A weigh-filling machine dispenses liquid until scales indicate the target weight, ensuring precise loads. This method prevents overflow or spillage in big containers and is often used in chemical plants and paint factories. For instance, a semi-automatic 10L chemical filler automatically fills a drum by weight, protecting operators from spills and ensuring consistency.
• Piston Filling:Common for viscous fluids like syrups, creams, and sauces. A pneumatic or servo-driven piston draws the product into a cylinder and then forces a fixed volume out each stroke. Piston fillers are simple, accurate, and easy to clean, making them cost-effective for foods (honey, ketchup) and cosmetics. For tighter accuracy, servo-controlled pistons offer precise volume control between runs.
• Pump Filling (Gear, Lobe, Rotor Pumps):Uses rotary pumps to achieve continuous flow. Gear pumps handle medium-viscosity liquids (oils, serums, liquid supplements) by providing steady pressure and flow; volume is adjusted by pump speed. Rotary/ lobe pumps are gentle on chunkier or shear-sensitive products (peanut butter, chunky sauces, creams). A rotor pump moves product with low shear, so textures and particles stay intact. These pump-based fillers are versatile and are the workhorses for filling everything from cooking oil and shampoo to honey and mayonnaise.
• Flow Meter Filling:Highly accurate for thin-to-medium beverages. A flowmeter filler measures actual liquid flow to stop filling at an exact volume. This ensures each bottle is consistently filled, minimizing waste. Flowmeter systems can handle water, juices, milk, and other low-viscosity drinks. They are fast and easy to integrate on automated production lines, making them attractive for modern beverage plants looking for precise, high-speed filling.

Each filling mode is chosen based on product properties. For example, foamy soft drinks suit vacuum fillers, large drum oils suit weigh fillers, and fruit syrups or condiments suit piston or pump systems.

Our experts work with customers to recommend the right mechanism for their specific liquid (be it an oil filling machine, paint filling machine, or any specialty filler).

Yundu’s Advanced Pump Technology

A key advantage of Yundu machines is our in-house pump technology. We have developed high-precision peristaltic and ceramic pumps that excel in demanding environments. Our ceramic piston pumps use silicon carbide and alumina ceramic components processed to micron-level accuracy, yielding stable, precise filling even for highly corrosive liquids. In practice, this means our pumps can handle strong acids, solvents, and abrasive fluids without wear or leaks.

The ceramic pump’s fine control ensures dosage precision down to a tiny fraction, which is crucial when filling high-value or hazardous fluids. We also offer peristaltic pump options for gentle, contamination-free dispensing. In short, Yundu’s proprietary pump designs give superior accuracy and durability across oil, chemical, food, and cosmetic lines.
