Melt-pumps for extrusion and compounding

melt-pumps eproteceprotec's melt-pumps (extrusion pumps, metering pumps or gear pumps) are  installed in all applications in extrusion and compounding of plastics. Melt-pumps are installed to build-up constant pressure and guarantee constant output. Extruder screw is released from pressure, this enables higher out output and enhance flexibility of process. Smooth, efficient and constant pumping of plastic melt through extrusion-die guarantees product quality and dimension. eprotec offers its melt-pumps also together with drive-unit and control.

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. With a melt-pump 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 coating and/or bearing materials, etc.
