Precise dosing of oils from IBCs with ±1% accuracy

Various mineral oils are to be precisely dosed from IBCs into an extruder. The requirement is for precise, automated filling with a defined flow rate and constant pressure.

Solution
F 430 S drum pump with mechanical seal, paired with an F 457 commutator motor and an FMO 110 flow meter

Task

Dosing different mineral oils from IBCs into an extruder. Filling is based on a preset quantity and must be automated and reproducible. The goal is to ensure a continuous supply to the process under defined flow parameters.

Requirements
  • Dosing accuracy ±1%  
  • Flow rate 60 l/min  
  • Delivery pressure 1 bar 
Solution in Detail

A filling system consisting of an F 430 S drum pump, an FMO 110 flow meter, and FLUXTRONIC® controls dosing in batch mode. Once the target volume is set, the pump starts automatically and stops when the target volume is reached. Additional control is provided by a switching amplifier and valve technology.

Result

Dosing accuracy of ±1% for specified quantities

Automatic batch operation reduces the amount of operator intervention

Continuous supply through automatic refilling

No need to change the IBC during operation
