Drum Liquid Weighing Filling Machine

General description

The NPACK drum liquid weighing filling machine is a piece of packaging equipment used to weigh and fill liquids into 100L to 300L drums. A weighing platform (weighing system), a filling nozzle or several filling nozzles, a control panel, and a roller conveyor system comprise the majority of the equipment. The weighing platform measures the weight of the drum before and after filling to ensure that the correct amount of liquid is filled. The filling nozzle is used to transport liquid by gravity or pump from a storage tank or container to the drum. The operator can set and monitor the required weight of the filled drum, as well as regulate the filling process, using the control panel. The conveyor system is used to move the drums to and from the filling station.


Npack has both automatic and semi-automatic drum liquid weighing filling machines, both controlled by PLC and used mostly for chemical, liquid, and oil products.The drum liquid weighing filing machine is used to package liquids in various sizes of drums. It’s widely employed in industries including oil, chemicals, and food processing. The machine precisely administers the exact amount of liquid required for each container while maintaining the correct weight. The machine can handle both non-viscous and viscous liquids and can be adapted to meet the specific needs of various sectors. The drum liquid weighing filing machine improves production productivity, lowers labor costs, and improves package accuracy and consistency.

Main Applicaton fields:

  • Oil
  • Solvent such as thinner
  • Liquid sugar
  • Cooking oil and resin
  •  Resin
  • Food and beverage such as soy sauce
  • Paint and varnish
  • Other liquid chemicals
