The C1C 5V PWM Circulating Pump is part of our C series micro centrifugal pumps. It is powered by a three-phase brushless DC motor and is designed to be quiet, compact and lightweight.

This pump has a variety of features, including a seal-less design to prevent leakage. It also has a wide range of working voltage providing stable performance.

The C1C 5V PWM Circulating Pump is designed for general, commercial and industrial applications. It is an excellent choice for all circulation pump applications.

It will pump fresh water, seawater, and other liquids. The other liquids need to be compatible with the pumps materials and that are of similar viscosity to water.


  • Highly efficient ECM three-phase brushless DC motor
  • Can sustain a continuous 24-hour workload
  • Life expectancy: over 20000 hours
  • Advanced magnetic drive technology
  • The rotor-impeller and the shaft are sealed together preventing leakage
  • Only one moving part: the magnetically driven rotor-impeller spins on a single ceramic bearing
  • High precision and wear resistance
  • Unique Closed Impeller: dynamically balanced, higher efficiency, stronger pressure performance, steady flow, smooth ultra-quiet operation
  • Stuck impeller protection
  • Over-voltage protection
  • Overload protection
  • Over-current protection
