Extrusion gear pump compact and compatible:
Extrusion gear pumps are of compact design and impress through their extraordinary compatibility. Their light construction and compact design allow simple installation, thus saving time and valuable floor space. The extrusion gear pump can be operated with viscosities of up to 30.000 Pas. temperatures of 350°C, suction pressures of up to 120 bar and differential pressures of up to 250 bar.

The standard extrusion melt pump is delivered with aluminum-bronze viscoseals. This dynamic shaft seal is designed especially for high viscosities and suction pressures and can be provided with cooling if required.

Because of the efficient build-up of pressure in comparison to extruders, the product can be conveyed in a very gentle manner with the gear pumps for sale, as comparatively little energy or heat is transferred to the polymer. They allow an extremely precise and almost pulsation-free conveyance of polymer, so that fluctuations in conveyance by the extruder will be compensated for. The friction bearings are provided with special lubrication pockets and channels to ensure long-term, reliable operation.
