Kontinuer Lamella Pumps transport the raw material with a high viscosity index, such as entrails and crushed bones, from pigs, cattle or whole carcasses from poultry and fish, except feathers. The transport is done in a pump, with a rotating blade movement, thus creating a positive offset. This Lamella pump system allows large quantities of materials to be transported for long distances using only one actuation. At the end of the process, valves installed in the tube extension clean the system, thus avoiding the accumulation of material between processing intervals.
