Heliatos HS-21 Solar Circulation Pump

This pump can be powered from any 12V source or directly from a PV Solar Panel. In Solar applications having the pump powered directly from a PV panel assures that the pump power is controlled by the intensity of the sun. This can completely eliminate the need for controllers, thermostats, and sensors.
Since the pump can also be powered from 12V sources it is suitable for a host of applications in cars, boats, and RV's that require high temperature and pressure capability, or anywhere where connection of your plumbing system to hazardous grid power voltages is not desirable.
