Gear Pump Measurement Systems handle low to medium-viscosity liquids with rapid changeover capabilities. The Multi-head Gear Pump Liquid Filling Machine (DLF200-6QS/8QS series) incorporates specially designed encoders that maintain filling accuracy within ±0.5%, while the tool-free fast-disassemble design enables thorough cleaning without specialized equipment—a critical feature for food and pharmaceutical compliance. Automatic bottle detection prevents spills through missing bottle, jam, and fall-down sensors. Double-speed filling modes (fast-slow cycles) minimize bubble formation during high-speed operations.

Magnetic Gear Pump Technology serves easy-flow liquids such as perfumes and essential oils, with industrial models achieving flow rates up to 120L/min per pump. The Automatic Pails Rotating & Filling Line (DLF200-5QS) exemplifies this technology's industrial application, featuring automated pail alignment that tracks and rotates 5-30L containers to ensure precise nozzle positioning. Integrated CIP (Clean-In-Place) circulation lines with manual valve control streamline sanitation protocols.

Piston Pump Systems address high-viscosity materials including creams, pastes, honey, and engine oil. The HSP Series Automatic 4/6/8 Heads Piston Pump Filling Machine employs servo-driven pistons that can be motor-extracted for rapid cleaning, eliminating manual disassembly labor. Diving nozzles insert directly into containers during filling to prevent foaming, while recipe storage capacity for up to 60 product parameters enables swift changeovers. Anti-drip protection combines pneumatic nozzles with drip trays to minimize product waste. These systems achieve production rates up to 3,600 bottles per hour for 500ml containers.

Weighing Scale Measurement provides the highest accuracy for large-volume industrial packaging. The Drum/IBC Filling Machine (ADF/BDF-1200 Series) handles containers from 50kg to 1,500kg using multi-level filling speed cycles (slow-fast-slow sequences) that improve weighing precision to ±0.1%. Explosion-proof configurations meeting ExdIIBT4 grade standards are available for hazardous chemical environments, with specific design features for 1,000kg IBC tanks and palletized drums.

All systems integrate PLC (Programmable Logic Controller) architecture with HMI touchscreens for digital parameter management. Servo-driven motion control synchronizes nozzle and piston operations for high-speed precision. Standard SUS304 stainless steel construction can be upgraded to SUS316 for corrosive material compatibility, with customizable nozzle diameters ranging from 4mm to 40mm.
