The feed screw pump is a positive displacement slurry pump that requires forced feeding and meets food hygiene standards. Its biggest feature is strong adaptability to the medium, stable flow rate, small pressure pulsation, and high self-priming ability, which cannot be replaced by any other pump type. Smooth and stable operation, low noise, no pulsation, no shear, capable of bi-directional rotation and bi-directional conveying (with reverse stator required).
