With the extrex⁶ EC, Maag presents the first gear pump specifically designed for the continuous conveying of rigid PVC (polyvinyl chloride). The new development addresses the thermal sensitivity of the material through a gap-free design without dead spaces. This effectively prevents the material from sticking and stagnating in the pump, which significantly reduces thermal stress and counteracts the risk of degradation.
The uniform, pressure-stable conveying relieves the extruder during operation. Depending on the application, this allows either material throughput to be increased or, at a constant throughput, energy savings of up to 50% to be achieved in the extruder. In addition, the design enables optimized temperature control in the melt process. Since this lowers the thermal stress on the material, the use of expensive stabilizers can be partially reduced, representing a direct economic advantage for the processor.
