Cast-steel reject pumps

The main area of use is in pulping processes in paper- and cardboard-manufacturing plants that employ waste paper as a raw material. The FAM reject pump is installed between the pulper and the contaminant-separating machine. It supplies pumped material with absolute reliability, even in the presence of coarse impurities.

The FAM reject pump can also be used as a processed-material drainage pump.
