Challenges in Pumping Non-Newtonian Fluids
Pumping non-Newtonian fluids poses unique challenges due to their viscosity altering properties under shear stress. Understanding and managing these changes are crucial for efficient and effective pumping processes. AxFlow recognizes the complexities involved, emphasizing the necessity to avoid shear and excessive heat during the pumping of these diverse fluids.
Shear Sensitivity: Non-Newtonian fluids exhibit varying viscosity based on shear rate, making shear sensitivity a primary concern. Sudden changes in viscosity can impact pump performance and the properties of the fluid being pumped.
Heat Management: Excessive heat generation during pumping can alter the properties of non-Newtonian fluids. Careful temperature control is essential to maintaining the fluid's desired characteristics.
Handling Non-Newtonian Fluids:
- Low Shear Pumping Action: AxFlow offers a wide range of positive displacement pumps specifically designed to provide low shear pumping actions. These pumps minimize shear stress on the fluid, preserving its unique viscosity and ensuring efficient transfer.
