Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of sludge reflux pumps, it is recommended to prioritize confirming key parameters such as flow rate, head, and material to ensure compatibility with the treatment capacity and corrosive medium characteristics of the sewage treatment system.
  • In municipal sewage treatment plants or industrial wastewater treatment scenarios, the appropriate pump type should be selected based on the sludge concentration. For high concentration sludge, wear-resistant spiral centrifugal reflux pumps can be considered.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to reduce procurement risks.
  • Long term operation of sludge reflux pumps requires attention to energy consumption indicators. It is recommended to compare energy efficiency data of different models and evaluate operating costs based on actual working conditions.
