6. Can Syrups Be Filled Using Liquid Filling Machines? Which Filling Machines Are Best for Different Syrups? What Should You Know About Filling High-Viscosity Syrups?|Neostarpack

Yes. Most room-temperature syrups—such as fructose syrup, vanilla syrup, caramel syrup, and brown sugar syrup—can be filled using the right type of liquid filling machine.
However, the filling solution must be selected based on syrup viscosity, crystallization tendency, production speed, and container type.
Syrups are generally medium- to high-viscosity liquids, which behave very differently from water-like products. To maintain stable flow, high filling accuracy, and proper hygiene, specialized filling mechanisms are required.
Neostarpack typically recommends gear-pump FG Series filling machines for syrup applications. Gear-pump fillers handle thick, slow-flowing syrups effectively and deliver stable, accurate, and continuous volumetric filling.


1. Which Filling Technologies Are Suitable for Syrup Products?

Depending on syrup viscosity and process requirements, the most commonly used filling technologies include:
 1) Piston Fillers
Best suited for very thick, slow-flowing syrups and paste-like liquids.
Key advantages:
• High accuracy even when viscosity varies slightly
• Positive displacement ensures repeatable volume per cycle
• One of the most reliable solutions for high-viscosity products
Neostarpack FP Series examples:
FP1010 Big Volume Tabletop Piston Pump Liquid Filling Machine 
FP2100 Semi-Automatic Piston Pump Filling Machine 
FP1005 Semi-Automatic Benchtop Liquid Filler 
FP1002 Automatic Piston Filler (Small-Volume Dosing) 
FP5150 / CC4000 / LR3000 Chemical Filling, Capping & Labeling Lines 

2) Gear Pump Fillers
Ideal for medium- to high-viscosity syrups such as fructose syrup, caramel syrup, and brown sugar syrup.
Key advantages:
• Smooth, stable flow control
• Excellent for continuous production
• High dosing accuracy for viscous liquids
• Neostarpack FG Series examples:
FG1000 Semi-Automatic Benchtop Liquid Filling Machine 
FG1100 Semi-Automatic Servo-Driven Gear Pump Filler 
FG2100 Dual-Head Filling Machine 
FG5400 8-Nozzle Gear Pump Liquid Filler 
FG5650 Automatic Liquid Filling Machine 
FG5470-CS4150-LD4000 Fully Automatic Filling, Capping & Labeling Line 

Our suggestion is to provide a sample test before purchasing the filling machine.
