Technical Case Study: DAE Pumps' Slurry Pumps in Successful Sewage Pumping Applications at a Large Wastewater Treatment Plant

This technical case study explores the implementation of DAE Pumps’ innovative slurry pumps in sewage pumping applications at a major wastewater treatment plant. The success story highlights the efficient handling of challenging substances like grit and sludge, showcasing the superiority of DAE Pumps’ submersible slurry pumps in enhancing wastewater processing operations.

Introduction: Wastewater treatment plants play a pivotal role in maintaining ecological equilibrium by processing sewage and facilitating the safe discharge of treated water. An essential aspect of these plants is sewage pumping, which involves transferring sewage laden with abrasive elements, grit, sludge, and other solids.  DAE Pumps, a leading manufacturer of submersible slurry pumps, provided a tailored solution to address the challenges associated with sewage pumping.

Customer Background: The wastewater treatment plant is a large-scale facility serving a densely populated urban area. The plant’s sewage pumping systems faced persistent issues related to pump clogging, abrasion damage, and reduced operational efficiency due to the abrasive nature of the sewage and the presence of grit and solid particles.


A large wastewater treatment plant grappled with several challenges within its sewage pumping systems, including:

  • Abrasion and Clogging: The presence of abrasive elements, grit, and sludge often caused clogging and accelerated wear-and-tear in traditional wastewater and sewage pumps.


  • Variable Flow Rates: Managing fluctuating sewage flow rates while maintaining consistent performance proved complex with conventional pumps.


  • Efficiency and Maintenance: Frequent clogging demanded excessive maintenance, leading to downtime, reduced operational efficiency, and increased costs.

  • Chemical Corrosion: The exposure to corrosive chemicals and gases in the wastewater led to the deterioration of pump components and materials, reducing the overall lifespan of the pumps and increasing the need for replacements and repairs.
