Servo driven auger feeders from Wolf for the highest degree of performance and dosing precision: SD 25 Servo, SD 50 Servo and SD 80 Servo

WOLF auger filling for an accurate, cost-conscious volumetric dosing of powdery to fine-grain products. Corresponding to the Finished Pack Regulation (FPR).

If powdery or fine-grained products must be dispensed in a particularly gentle and dust free manner, the WOLF auger dosing units will absolutely convince with their dosing accuracy and performance of up to 160 cycles/min in volume ranges from 0.5 up to 20000 cm3

This also applies to free flowing and sluggish, fresh, sticky and dust-generating products, for example, spices, coffee, Baby food, chemical and pharmaceutical powders and granules.

The servo driven auger feeder from WOLF are used as a stand-alone unit for the direct filling into according receptacles. And also synchronized with a packaging machine.

The high dosing accuracy, without variations of the bulk weight, avoids overfilling and saves the products to be packed.

  • The highest degree of weight accuracy due to servo drives and modern electronics, which enables a continuous, precise adjustment of the auger rotation.
  • Reduced overfilling saves material, standard deviations of +/-0.5%. 
  • This will provide a quick amortisation, often within one year.
