With the same principles of the PLE, but with different materials: the use of tool steels increases the temperature resistance. These pumps are used for melted polymers, and high-temperature polymer reactions.
PAE pumps can be heated electrically or through an appropriate fluid, maintaining the process temperature.
A full range of small pumps is available, from 0,3 to 30 cc/rev pumps, able to be mounted directly on 3D-Printing robot arms.
