about e p r o t e c

eprotec melt pumps (gear pumps) have an optimized design for the discharge, squeezing-out process. This guarantees continuous and gentle polymer transport under the most varied of extrusion conditions of pressure, temperature and viscosity. With the melt pump, which builds up the pressure between the extruder and the die or pelletizer, extrusion parameters can be configured in order to guarantee a homogeneous melt with increased throughputs and smallest end product tolerances. For more than 40 years, polymer processors have been using gear pumps in sheet, board and profile extrusion. As well as in the production of highly filled compounds to solve critical processes in the demanding polymer processing industry.

As an end user we offer you the following advantages:

• Improved dimensional stability - the melt pump smooths the pulsations (pressure
fluctuations, surge) of the extruder screw
• Controlled melt quality - with the melt pump the counter pressure of the extruder will be far
lower, thus less friction and therefore lower melt temperature
• Increased delivery rate - the gear pump makes it possible to process higher percentage of
regrind and still maintaining the smallest tolerances
• Reduced consumption of raw materials through tighter tolerances
• Optimized faster start-up process by pump inlet pressure control time savings can be 50%
• Enlarges service life of the processing unit. The compounding pump reduces the axial force
and power consumption of the extruder
• Encreased productivity and process stability the extrusion pump is an efficient component for
conveying, eliminating quality problems and increasing production volume
