Drum Liquid Weighing Filling Machine

The NPACK drum liquid weighing filling machine is a packaging equipment used to weigh and fill liquids into drums which is from 100L to 300L. The whole machine usually consists of a weighing platform(weighing system), a filling nozzle or multi filling nozzles, a control panel, and a roller conveyor system. The weighing platform is used to accurately measure the weight of the drum before and after filling, ensuring that the correct amount of liquid is filled. The filling nozzle is used to transfer the liquid from a storage tank or container to the drum by gravity or pump. The control panel allows the operator to set and monitor the desired weight of the filled drum, as well as control the filling process. The conveyor system is used to move the drums to and from the filling station.


Npack have both automatic and semi automatic drum liquid weighing fillling machine, both are controlled by PLC, mostly application in Chemicals liquids, oils products.The drum liquid weighing filing machine is used for packaging liquids in drums of various sizes. It is commonly used in industries such as oil, chemical, and food processing. The machine accurately dispenses the exact quantity of liquid required for each container, while ensuring that the correct weight is maintained. The machine is capable of handling non-viscous as well as viscous liquids, and can be customized to accommodate the unique requirements of different industries. The drum liquid weighing filing machine helps to improve production efficiency, reduce labor costs, and increase accuracy and consistency in packaging operations.

  • 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
