Melt-pumps for extrusion and compounding
eprotec's melt-pumps (extrusion pumps, metering pumps or gear pumps) are installed in all applications in extrusion and compounding of plastics. Melt pumps are used to build up constant pressure and ensure constant output. The extruder screw is relieved, this enables a higher output power and increases the flexibility in different applications. Smooth, efficient and constant pumping of plastic melt through extrusion-die guarantees constant product quality and dimension. eprotec also offers its melt pumps together with a drive unit and controller.
Retrofitting of extrusion-lines with melt-pumps leads primarily to a constant throughput. This is a requirement for dimension stability of extruded product. Retrofitting with melt-pumps leads mostly to higher output of extrusion-line. When a melt-pump is installed in extrusion-line the screw is not anymore responsible for the full pressure build-up.
Specifically designed for application:
eprotec melt-pumps are designed precisely for every application. According viscosity, throughput, processing temperature the pump-size, surface coating, tolerances e.g. are determined. Type and amount of fillers determine specific surface coating and bearing materials.
