Due to the strictly volumetric conveying priniciple of the gear pump, the temperature development is nearly independent of the counter-pressure. Because of this, the use of a gear pump is suitable wherever high extrusion pressures are required. With the roll-ex® gear pump technology pressures of up to 800 bar are possible.
- constant temperature with increasing counter-pressure
- particularly gentle material treatment
- easy and quick change of material
- simple material change
