Its conception is very old (Archimedes, born around 287 B.C. and died in 212 B.C.), but the Archimedes screw is an extremely complex mechanical element and works “full powder”.
In some configurations, the screws meet the ATEX and Food Contact criterion. When the screws are inclined, it is better that their moto reduction group is placed at the head, so that the shaft turns working in extension. The screws which operate on the principle of relative friction between the trough and the shafts inevitably undergo some form of wear.
The latter being unavoidable, this leads to screws made of stainless steel. ISERCO limit the shafts rotation speeds to increase their lifetime.
The ISERCO design of ARCHIMEDEAN screws minimizes any mechanical component in the product. Thus, the intermediate bearings do not exist in our products.
