Specifications of the C1D Circulating Pump PWM 5V:

  • Static PSI – 58.0 / 4 Bar
  • Inlet / Outlet – 18mm x 18mm
  • Can be run directly from PV


The C1D 5V PWM Circulating Pump is part of our C series micro centrifugal pumps. It is powered by a three-phase brushless DC motor. The C1D PWM is designed to be quiet, compact and lightweight.

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

The C1D 5V PWM Circulating Pump is designed for general, commercial and industrial applications. It is a good choice for all circulation pump applications.

It will pump fresh water, seawater, and other liquids. Any other liquids need to be compatible with the pumps materials and 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
  • Wear resistance
  • Over-voltage protection
  • Overload protection
  • Over-current protection
  • Stuck impeller protection
  • Unique Closed Impeller: dynamically balanced, higher efficiency, stronger pressure performance, steady flow, smooth ultra-quiet operation

Areas of use of the C1D Circulating Pump PWM 5V:

  • Water Circulation, treatment and purification
