Melt devices which transport plastic melts along with the empty volume of gear toothing in the pump shaftpolymer
Product Description
The volumetric pumping device has two externally toothed gear wheels that mate with each other when they rotate. A small pressure in the pump inlet is sufficient to fill the tooth chambers. On the discharge side, the mating of the gear teeth in each other forces the melt out of the tooth chambers. The forces on each of the gear shafts are taken up by two slide bearings. These are lubricated by the plastic and are maintenance-free.
