Micro Wash Drain Pump for Smart Toilet Quiet B50

The DWP03-B50 is a 50mm wash and drain integrated brushless pump – a unique design that combines washing circulation and drainage functions in one compact unit. Driven by a three-phase brushless motor, it offers integrated functionality, higher efficiency, and intelligent control options compared to traditional dual-pump systems. This all-in-one design saves space, reduces system complexity, and lowers overall cost for compact appliance applications.

  • Baby-safe food-grade certified – Safe for baby bottle cleaning applications
  • Three-phase brushless motor for efficient, reliable operation
  • Integrated washing circulation and drainage in one pump
  • Rotor and impeller molded as one piece for higher efficiency
  • High-precision ceramic shaft for extended life and low noise
  • Fully sealed motor section with water-electricity separation for safety
  • Supports speed regulation and diversified protection functions
