Industrial Solid Volume Pump Feeder Machine For Chemical And Food Industries

I. Core Design Features

1. Volumetric Feeding Principle
   Utilizes a twin-screw or gear structure for precise volumetric control, with mechanical components forming sealed chambers that continuously rotate to propel materials. This design avoids shear damage, suitable for free-flowing powders and granules (e.g., plastic pellets, food ingredients) with a feeding range of 2–6,700 liters/hour .

2. Gentle Conveyance and Precision Assurance

   • Low-Shear Design: Twin-screw meshing reduces material compression, preventing degradation of heat-sensitive materials .
   • Weight Feedback System: Compatible with SFT-II technology (hanging or platform-style load cells) for real-time monitoring and联动calibration with volumetric data, achieving ±0.5% accuracy .

3. Modular Design and Compatibility

   • Four Model Options: Different screw diameters and speeds accommodate low-volume (2 L/h) to high-capacity (6,700 L/h) requirements.
   • Quick-Disassembly Structure: Spherical hoppers and horizontal mixers prevent material buildup, with stainless steel or wear-resistant alloy options for corrosive or high-temperature environments .

II. Typical Application Scenarios

1. Chemical and Food Industries: Precise conveying of plastic pellets, additives, sugar powder, and milk powder for continuous production lines or batch blending systems .
2. Pharmaceutical and Energy Sectors: Used for metering lithium battery cathode materials or pharmaceutical excipients, meeting GMP cleanroom standards .
3. Automation Integration: Supports remote start/stop, flow adjustment, and anomaly alarms via PLC/DCS systems .

III. Technical Advancements

1. Smart Control Optimization
   Integrates PID algorithms and density compensation to maintain stability despite material density fluctuations.
2. Maintenance Efficiency
   Open-frame design and tool-free disassembly enable screw replacement and chamber cleaning within 10 minutes .
