Nordson BKG® melt pumps are designed to handle viscous polymer melts accurately and consistently, ensuring a stable and efficient production process. Let's explore some of the key advantages they offer:
Precise and Stable Flow Rate
One of the most significant benefits of using a Nordson BKG® melt pump is their ability to deliver a precise and stable flow rate. Traditional extruders can experience fluctuations in output due to variations in material feed and screw speed. Melt pumps provide a controlled and consistent volume of polymer melt, relieving stress from the extruder. This is critical for applications requiring tight tolerances and uniform product thickness, such as film extrusion, sheet production, and fiber spinning.
Superior Pressure Control
Melt pumps are adept at generating and maintaining consistent pressure in the melt stream. This precise pressure control is essential for:
- Uniform Die Flow: Ensuring that the polymer melt is distributed evenly across the die, minimizing variations in product thickness and quality.
- Improved Material Consistency: Avoiding inconsistencies due to pressure fluctuations and ensuring a more homogeneous melt for better product characteristics.
- Optimized Extrusion Conditions: Allowing for more efficient processing parameters and reduced risk of material degradation.
Enhanced Melt Quality
Nordson BKG® melt pumps contribute to improved melt quality. By maintaining a consistent flow and pressure, they minimize shear and temperature variations within the melt, leading to:
- Reduced Material Degradation: Lower shear rates reduce the risk of polymer degradation, preserving the desired mechanical and optical properties of the finished product.
- Improved Homogeneity: A more homogeneous melt results in better color dispersion, fewer defects, and enhanced mechanical properties.
- Reduced Gel Formation: Consistent processing conditions can minimize the formation of gels and other unwanted byproducts, improving overall product quality.
Increased Extrusion Efficiency
By stabilizing the entire extrusion process, Nordson BKG melt pumps can contribute to significant increases in efficiency:
- Higher Output Rates: The precise control allows for more consistent processing parameters, often leading to the ability to operate at higher output rates.
- Reduced Downtime: Stabilized flow and pressure minimize process variations, reducing incidents of material jams and shutdowns.
- Lower Scrap Rates: Consistent product quality translates into less wastage and lower overall material costs.
Robust and Reliable Structure
Nordson BKG® melt pumps are engineered for demanding industrial environments. They are constructed from high-quality materials, ensuring durability and reliable performance, even under high pressures and temperatures. This robust design translates into a longer operational lifespan and reduced maintenance requirements.
Flexible Integration
Nordson offers a variety of melt pump models to suit different applications and processing needs. They can be integrated into existing extrusion lines and are adapted according to your requirements, which makes them suitable to a wide range of polymer processing operations.

FAQs
-
Q: What factors should I consider when choosing a melt pump?A: It is essential to consider your application when choosing the best gear pump to enhance your polymer processes (for example whether you’re looking for a melt pump for plastic extrusion, polymerization, pelletizing, or compounding). You should also consider the viscosity of the polymer or other material you’ll be using, the operating temperature, and what changes you’d like to see in the output or end product.
-
Q: How are gear pumps important to the extrusion process?A: Extrusion gear pumps enable consistency in thickness, reduce imperfections, and enable precision and accuracy. Thanks to a uniform output, they ensure a high-quality end product. Extrusion gear pumps can also help reduce waste and the amount of energy used during the extrusion process.
-
Q: Do you offer customization to ensure your gear pumps fit my needs?A: Yes, we can configure your chosen melt pump to ensure it best meets your needs, and upgrade parts to ensure it is fully optimized. We encourage you to get in touch with an expert to ensure you receive the best possible polymer melt pump for your application.
-
Q: I already have an extrusion system; can I add a polymer melt pump to it, and where?A: It’s very likely that a polymer gear pump will be able to enhance your existing setup. Typically, an extrusion melt pump will sit between the extruder and the die. Our team can help identify any modifications that may be required to ensure the extruder pump works well with your technology.
-
Q: What kind of maintenance tasks should I expect?A: It’s important to keep your polymer gear pump clean. Your cleaning schedule will depend on the type of polymer being processed, so our experts can help with specific guidance tailored to your application. It’s also important to keep in mind that seals may need replacing over time, due to wear.
