The Explosion Proof Liquid Weight Filling Machine is specially designed for safely and precisely filling flammable or volatile liquid products. Built with an anti-explosion electrical system, it ensures secure operation in hazardous environments while maintaining exceptional filling accuracy.
This above-surface filling system allows the operator to easily position the drum under the filling nozzle. Once the start button is pressed, the machine automatically tares the weight and performs a two-speed filling process—fast for bulk flow and slow for precision. Upon completion, the filling valve automatically retracts, and a drip collection system prevents product leakage, ensuring a clean and efficient workflow.
Ideal for chemical, petrochemical, coating, and solvent industries, this explosion proof liquid weight filling machine offers a combination of safety, reliability, and high-speed performance, making it an essential solution for modern hazardous-area liquid packaging.

Core Components of an Explosion-Proof Liquid Weight Filling Machine
An Explosion Proof Liquid Weight Filling Machine is built around four essential modules that work together in hazardous environments to ensure safe, stable, and highly accurate liquid filling.
Core Components:
Explosion-Proof Control Center
A flameproof control cabinet integrating a PLC and touchscreen HMI, providing centralized control while ensuring full compliance with explosion-proof safety requirements.
High-Precision Weighing and Sensing Unit
Explosion-proof load cells and a reinforced weighing platform deliver real-time, high-accuracy weight measurement for precise liquid filling control.
Explosion-Proof Filling and Actuation System
Filling nozzles driven by explosion-proof pneumatic or servo systems, combined with a stable conveyor system to ensure smooth, controlled filling operations.
Comprehensive Safety Protection System
A fully explosion-proof machine structure, integrated static electricity elimination devices, and emergency stop functions to maximize operational safety in flammable or explosive environments.
Operation Process of Explosion-Proof Liquid Weight Filling Machine
After power-on, the operator places the barrel on the weighing platform and presses the [START] button. The system automatically performs tare deduction, then opens the filling nozzle and ball valve to begin filling. A three-stage flow control (large, medium, small) ensures safe and accurate filling of flammable liquids. When the target weight is reached, filling stops and the nozzle lifts up, completing the explosion-proof filling process.
