YCWQ Series High-Efficiency Permanent Magnet Submersible Sewage Pump

The YCWQ Series High-Efficiency Permanent Magnet Submersible Sewage Pump represents a new generation of ultra-energy-efficient products, officially included in the Nanjing Innovation Promotion Demonstration Product Catalog. The hydraulic components are optimized through CFD (Computational Fluid Dynamics) simulation, delivering high efficiency, anti-clogging, and anti-cavitation performance. The drive system utilizes a high-efficiency permanent magnet motor, featuring high power density, superior efficiency, high power factor, and compact design. Operating under vector frequency control, the unit ensures stable performance and avoids inefficiencies caused by improper model selection, expanding the effective operating range.
