The auger pump fitted in the machine is a so-called displacement
pump. An screw conveyor (rotor) rotates inside a fixed screw convey‐
or barrel (stator). The screw conveyor is made from a highly wear-re‐
sistant and extremely hard metal alloy; the screw conveyor barrel
from a steel sleeve with several slots and an elastic, vulcanised rub‐
ber core.
