In three different pump sizes (NPK 80, NPK 125 and KBK 200), they convey comminuted, hot meat-bone-fat mixtures. In the process, the water content is reduced with the help of evaporation. The end product: protein meals and fats from animal by-products of the so-called category 3.
Compared to other pumps, a general overhaul was necessary this year after 30 years of operation. After the pumps had been in operation almost continuously for all these years, the KBK pump housing had to be replaced. The corresponding pump housing was already in stock as a spare part (more than 20 years).
