NP-OF Overflow Liquid Filling Machine
  1. Parts in contact with liquids comply with GMP standards,304 or 316SS. When filling, the filling head extends into the bottle, and the bottle mouth is sealed to ensure that the liquid does not bubble or overflow, and the liquid level in the bottle is consistent.
  2. The filling head has the function of sucking back, and there is no leakage phenomenon. No filling when the bottle is not in place, ensuring error-free operation and keeping the work area clean.
  3. This machine has only one filling pump, one top tank and one side stand tank which can be equipped with 2~20 filling heads, and the output and filling volume can be adjusted according to your need.
  • vacuum filling system
  • the filling nozzle is driven by a servo motor to move up and down
  • the specially designed overflow filling nozzle.
  • In cases involving highly corrosive liquid products, this machine can be equipped with PTFE pumps, PTFE hoses, and sealing materials. This configuration effectively prevents corrosive damage to the machine, ensuring its longevity and reliability even when handling aggressive substances.
