Technological Trends in Water Treatment Pumps: Ensuring Efficiency and Sustainability


In response to the evolving needs of the water treatment industry, the technological trends in water treatment pumps are advancing across several crucial aspects.

Technical Research on Pump Operation Safety

Water pumps play a pivotal role in the water treatment industry, directly influencing the normal operation of water treatment processes. Major faults in pump operation, such as impeller corrosion, fatigue fractures of blades, wear of pump body flow components, shaft bending, and motor/bearing burnouts, can lead to process paralysis, causing significant inconvenience to people’s lives and production. Research on operational safety is paramount. By studying this aspect, not only can pump safety be enhanced, but its lifespan can also be prolonged.

Technical Research on Pump Automatic Control

In water treatment processes, water consumption and pressure in systems frequently vary. Failure to meet these changing requirements can disrupt normal production and result in significant waste. To manage this effectively, remote monitoring and on-site control of production systems are essential. Research in automatic control technology is a key trend to enhance production efficiency and safety. Current studies on variable frequency technology have yielded positive results, providing substantial economic and social benefits. Speed regulation has proven to be an energy-efficient method, enhancing pipeline efficiency and overall device performance significantly.

Technical Research on Pump Selection and System Energy Efficiency

Irregularities in pump selection and design contribute to energy waste, impacting energy-saving efforts. To address this:

  • Pump Selection Principles:
    1. Define pump performance parameters and necessary operating conditions reasonably.
    2. Design pumps based on site conditions to satisfy practical requirements.
    3. Consider pump’s maximum efficiency, efficient range, and actual usage efficiency.
    4. Conduct technical and economic comparisons to choose advanced and economically rational solutions.
  • Improving Centrifugal Pump System Efficiency Metrics: Analyze and research aspects like:
    1. Rational configuration of pump units within the entire production system to meet usage and energy-saving requirements.
    2. Proper configuration of centrifugal pumps and motors, considering energy-saving effects.
    3. Rational pipeline configuration to reduce pipelines and enhance efficiency.
    4. Rational configuration of transmission devices, which affects transmission efficiency and the efficiency of power machinery, pumps, and pipelines.
    5. Ensuring rationality in the system’s efficiency and vapor.

Research on Special Performance

Given varying usage conditions, additional research in special performance areas is essential, focusing on:

  1. Studying special transport media, such as solid-liquid mixtures.
  2. Researching materials with strong corrosion resistance and wear resistance.
  3. Exploring special structures, like non-clogging flow passages and dual-layer structures.
