Pumping Foams

Navigating the complexities of pumping foams demands a deep understanding of their unique characteristics. At AxFlow, we recognize the challenges posed by the presence of solids and air bubbles within these mixtures. With our range of precise positive displacement pumps, including hose, rotary lobe, eccentric rotating disc, and various diaphragm pumps, we ensure the gentle and efficient transfer of foams.

Challenges in Pumping Foams

Pumping foams, encompassing a diverse range from protein-based to fire retardant varieties, presents engineers with unique challenges due to the presence of solids and air bubbles within the mixture. These challenges demand specialized techniques to ensure smooth and efficient pumping processes.

  • Air Bubble Interference: Foams inherently contain air bubbles, which can lead to increased vibration, wear, noise, heat, and cavitation in pumps. These effects can significantly diminish pump performance, making it crucial to handle these air bubbles effectively.
  • Shear and Temperature Sensitivity: Many foams exhibit extreme sensitivity to both shear and temperature. Any alteration in their physical properties due to shear forces or temperature changes can impact their performance significantly. Precise control and gentle handling are imperative to maintain foam integrity.

Handling Foams

  • Specialized Positive Displacement Pumps: AxFlow's range of positive displacement pumps, including hose, rotary lobe, eccentric rotating disc, and various diaphragm pumps, offers tailored solutions for handling foams. These pumps provide the gentle pumping action required to preserve the foam structure and prevent performance degradation.
  • Air Release Mechanisms: Implementing air release mechanisms in the pump system helps manage and eliminate air bubbles, ensuring optimal pump performance and preventing issues related to vibration and cavitation.
  • Temperature and Shear Control: Utilizing pumps equipped with precise temperature and shear control mechanisms ensures that foams are handled within their specific temperature and shear tolerance limits, preserving their physical properties.

Examples of Foams and Foam Related Applications

  • Protein Foams: Used in firefighting and as a stabilizing agent in various industrial applications.
