The consolidation of the gear pump product line provides a clear market approved standard for each of the applications they serve. 2

4 BKG BlueFlow Pump Technology The complete perspective. The detail in focus. From today s point of view, the gear pump cannot be disregarded in extrusion, if high-quality products shall be produced. Despite the simple and robust design, the displacement pump provides a high degree of precision, accuracy, capacity and pressure build-up with minimal stresses. Whereas, the gear pump maintains a constant volumetric output and the required pressure at the tool, the pressure at the outlet of the extruder can be set to an optimal duty point. To ensure the highest quality of our gear pumps, Nordson manufactures all gear pumps in-house. In case there is a need to remanufacture or perform maintenance, all necessary spare parts are immediately available around the world. For nearly 60 years, we have served an abundance of markets globally providing us with the broadest range of experience in the industry. The Ideal Technology. Advantages of BKG BlueFlow Gear Pump Technology Excellence is our standard. Optimized down to the last detail. Rheologically optimized inlet and outlet sections Processing of products with a filler content of up to 85% powdery additives Processing of abrasive and corrosive fillers, sensitive and low viscosity materials Special sealing systems available depending upon the application Sizes available for all products / extruders Operation & Process Stability Reduces the stress on the extruder by shifting the pressure building responsibility to the gear pump Increased throughput of raw material by means of tighter manufacturing tolerances Reduction of rejects of the end product Improvement of the dimensional accuracy in the production of sheet and profile Product Quality Improvement of the product quality regarding homogeneity Elimination of throughput variations and pressure pulsations, thus improvement of the product quality Optimization of the surface and optical quality in the production of film, sheet and profile 3

5 Flowing efficiency Synchronizing the extrusion line made easy. By implementing a pump between the extruder and the die, you can influence the thickness of the final product directly and avoid pressure fluctuations and pulsations at the die. Extruder screws melt, mix and convey polymers, but cannot guarantee constant pressure and volume at the die. A gear pump is not designed for melting, or mixing, but a highly efficient instrument to build up pressure and charge the throughput of the polymer exactly. Installing a gear pump gives you additional control over the processes. The production line will become more flexible by: shortening the start-up when processing difficult materials the possibility to process several polymers with the same screw The pump control regulates the loop from the inlet pressure of the pump to the extruder. Regrind Pellet Additives $ Improved Screw Efficiency = Increased Rate Extruder without a gear pump +/- 4 6 % gauge in machine direction Extruder with a gear pump +/- 1 % gauge in machine direction Extruder Drive S C / P S/M Target specification Pump Drive $ Material Savings $ Improve Gauge Improve Screw Efficiency and Increase Output. Gear pumps build pressure efficiently, thereby reducing extruder head pressure. By reducing extruder pressure, a screw can operate more efficiently and can convey more material. By reducing the extrusion pressure a higher throughput can be achieved.
