This is the C1A Solar Pump. It is part of our C series micro centrifugal pumps. A three-phase brushless DC motor powers the C1A Pump. The C series pumps are designed to be quiet, compact and lightweight.

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

The C1A Solar Pump offered by USSolarPumps is specifically designed to cater to general, commercial, and industrial applications. It serves as an excellent choice for various circulation pump needs. This versatile pump is capable of efficiently pumping different types of liquids, including fresh water, seawater, and other compatible fluids.

However, it’s important to make sure that the other liquids being pumped are compatible with the materials used in the pump and have similar viscosity to water. By keeping that in mind, the C1A Solar Pump can effectively handle a range of pumping requirements.

Features of the C1A Solar Pump:

  • Highly efficient ECM three-phase brushless DC motor
  • Can sustain a continuous 24-hour workload
  • Life expectancy of well 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
  • Unique Closed Impeller — dynamically balanced, higher efficiency, stronger pressure performance, steady flow, 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 C1A Solar Pump:

  • Water heating mattress
  • Automotive air conditioning
  • Hot water circulating system
  • 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
