Summary
Introduction to AODD Pumps for High Viscosity Liquids
The episode introduces listeners to the intricacies of pumping high viscosity liquids, emphasizing the importance of proper design to avoid issues like slow flow rates and excessive wear on pumps. Daniel Getty, managing editor for Processing Magazine, discusses an article by Layton Jones, focusing on the use of Air-Operated Double Diaphragm (AODD) pumps, a preferred choice for handling viscous materials.
Understanding Viscosity Challenges
Pumping high viscosity products, such as sauces and silicones, presents unique challenges. The episode explains how improper system design can result in cavitation, jams, and decreased efficiency. Listeners learn about the necessity for adequate atmospheric pressure to move these materials and the role of barrel unloaders to mitigate suction pipe friction losses.
Calculating Friction Loss and Pump Sizing
The podcast delves into the critical calculations required for effective pumping systems. Engineers must account for internal friction losses when specifying pump size and pipe dimensions. Using friction loss calculators, they can optimize the design to ensure efficient material transfer without exceeding the pump’s suction capabilities.
Case Study: Improving a Cosmetics Processor's System
A detailed case study illustrates the struggles of a cosmetics processor when transferring high-viscosity products. By reconfiguring their system with larger pipe diameters and upgrading to a more efficient AODD pump design, they achieved desired flow rates, decreased pump wear, and significantly reduced maintenance efforts. The new system also enabled clean-in-place capabilities, optimizing labor time.
Conclusion and Further Learning
The episode wraps up with a reminder to subscribe to Processing Magazine for ongoing insights into industrial processing. Listeners are encouraged to apply the discussed principles in their operations to improve efficiency and reduce costs.
