The C1B Circulating Pump is part of our C series micro centrifugal pumps. A three-phase brushless DC motor powers C1B Pump. This pumps’ design makes it quiet and cause little disruption. It is also compact and lightweight.  The C1B has a seal-less design that prevents leakage. It also includes a wide range of working voltage providing stable performance.

The C1B is designed for general, commercial and industrial uses. This pump is ideal for all circulation pump applications. It will pump fresh water, seawater, and other liquids that are compatible with the pumps materials. Any liquid needs to be of similar viscosity to water.

Features of the C1B Circulating Pump:

  • Highly efficient ECM three-phase brushless DC motor
  • Can sustain a continuous 24-hour workload
  • Has a life expectancy of well over 20000 hours
  • Advanced magnetic drive technology
  • The rotor-impeller and the shaft are sealed together
  • Only one moving part: the magnetically driven rotor-impeller
  • The rotor-impeller spins on a single ceramic bearing
  • Highly precise
  • Wear resistant
  • Unique Closed Impeller: which makes the pump dynamically balanced, has stronger pressure performance, steady flow and a smooth, ultra-quiet operation
  • Three-phase brushless DC pumps have the advantage of various protection functions such as: stuck impeller protection, over-voltage protection, overload protection, over-current protection.

Areas of Use of the C1B:

  • Water heating mattress
  • Automotive air conditioning
  • Hot water circulating systems
  • Electric cars: radiators, heaters
  • Computer CPU cooling circulation
  • Liquid transfer general purpose pumping
  • Fountain, aquariums and larger fish ponds
  • Circulating systems for homes, RV’s and boats
  • Electronics cooling water circulation chiller systems
  • Cleaning equipment, purification and water treatment
