Semi Automatic Drum Filling Machine for Chemicals | ±0.2% Weighing System
When chemical manufacturers need accurate drum filling but do not require a fully automated production line, a semi automatic drum filling machine provides a practical solution.
The GLZON semi automatic drum filling system is designed for filling industrial liquids into 200L drums, 55-gallon drums, and similar containers. It combines operator flexibility with automatic weighing control, helping manufacturers achieve consistent filling results while keeping equipment investment reasonable.
Using a load-cell weighing system, the machine can achieve filling accuracy up to ±0.2%, reducing product giveaway caused by overfilling and improving filling consistency.
The system can be configured for different chemical applications, including lubricants, paints, coatings, resins, solvents, detergents, adhesives, and other industrial liquids.
For hazardous applications, explosion-proof configurations and ATEX certification options are also available upon request.

What Is a Semi Automatic Drum Filling Machine?
A semi automatic drum filling machine is a filling system where the operator handles some manual steps, such as placing the drum into position, while the machine automatically controls the filling process.
Compared with manual filling, it provides:
- higher filling accuracy
- reduced product waste
- more consistent filling weight
- easier operation
- better process control
Compared with a fully automatic filling line, a semi automatic system requires lower investment and offers greater flexibility for manufacturers producing different products or smaller batches.
This makes it suitable for many chemical manufacturers that need precision filling without a complete automation system.
High Precision Weighing Filling System
The biggest advantage of the GLZON semi automatic drum filling machine is its weight-based filling technology.
Instead of controlling filling only by time, the machine continuously monitors the actual weight during filling through load cells.
The filling process works in two stages:
Fast Filling Stage
The machine transfers most of the liquid quickly to improve production efficiency.
Slow Filling Stage
When the target weight is close, the system automatically reduces filling speed.
This allows the machine to approach the final weight more accurately.
With filling accuracy up to ±0.2%, the system helps manufacturers reduce:
- unnecessary product giveaway
- inconsistent filling results
- customer complaints caused by inaccurate quantities
For chemical products where material costs are high, precision filling can create significant savings over long-term operation.

Chemical Drum Filling Machine for Different Industrial Liquids
Chemical products have different characteristics.
A liquid with low viscosity, such as a solvent, behaves very differently from a high-viscosity resin or coating material.
Therefore, the machine configuration should be selected according to the actual product.
The GLZON chemical drum filling machine can be configured for:
- lubricating oil
- engine oil
- hydraulic oil
- paint
- coatings
- resin
- epoxy
- adhesives
- solvents
- detergents
- cleaning chemicals
- liquid fertilizer
- other industrial liquids
Before recommending the final configuration, we mainly need to know:
What liquid do you want to fill?
Our technical team can then help determine the suitable filling method, materials, and system configuration.
Chemical Resistant Materials and Filling Components
For chemical applications, material selection is one of the most important factors.
Different liquids may require different contact materials.
Available options include:
SUS304 Stainless Steel
Suitable for general industrial liquid applications.
SUS316 Stainless Steel
Provides improved corrosion resistance and is commonly selected for more demanding chemical applications.
PTFE Contact Parts
PTFE components can be selected when stronger chemical resistance is required.
The filling system can also be equipped with suitable:
- hoses
- valves
- seals
- gaskets
- filling nozzles
The correct material selection helps improve machine reliability and service life.
Explosion-Proof Drum Filling Machine for Hazardous Applications
Some chemical products require additional safety considerations.
For applications involving flammable or hazardous liquids, GLZON can provide an explosion-proof drum filling machine configuration.
Zu den typischen Anwendungsbereichen gehören:
- solvents
- paint thinner
- flammable chemicals
- petrochemical liquids
- coatings
Depending on the project requirements, the system can include:
- explosion-proof electrical components
- grounding system
- suitable pumps
- chemical-resistant contact materials
- safety-focused filling design
For customers requiring European hazardous-area compliance, ATEX certification options are available upon request.

The final configuration should always be selected according to the actual liquid properties and application requirements.
Flexible Filling Methods for Different Products
Different liquids require different filling methods.
Top Filling
The nozzle fills from above the drum.
Suitable for many standard industrial liquids.
Sub-Surface Filling
The nozzle enters inside the container during filling.
This can help reduce splashing and foaming.
Bottom-Up Filling
The filling nozzle starts near the bottom of the drum and rises gradually.
This method can be useful for:
- foaming liquids
- coatings
- solvents
- products sensitive to splashing
The filling method is selected according to the product characteristics.
Easy Operation with PLC and HMI Control

Although the machine is semi automatic, the filling process is controlled automatically.
The PLC and HMI system allows operators to adjust and monitor:
- target filling weight
- filling parameters
- machine status
- alarms
- operation settings
An English-language interface can be provided for international customers.
The simple operation design makes the machine suitable for manufacturers who need reliable filling without complex training requirements.
