Vacuum dosing feeder PFL Powderflex

volumetriccontinuous-motionfor powders

The PFL Powderflex* provides continuous and precise dosing and conveying of small to medium quantities of powder, whether the requirement is for the controlled charging of powders into continuous production processes or for predetermined precision dosing. The system comprises two small, calibrated chambers, each equipped with a flat filter in the upper part. A practically continuous powder flow or precise volumetric dosing is generated through a unique valve system, plus the combined effect of vacuum and pressure, which makes it possible to alternate, at high frequency, between filling and emptying the chambers. The transfer rate is easily adjusted by adapting the volume of the chamber or changing the frequency. The PFL extracts powder from any container, transferring it over considerable distances. Its simple design ensures minimal maintenance and makes rapid changes of product possible. Powder characteristics are not modified during transfer. The PFL is to powder what a peristaltic pump is to liquids.
