These tiny brushless, magnetic drive circulators can be driven by PV modules or 12 Volt batteries for closed-loop circulation in solar water heating systems, individual space heat zones and individual loop radiant floor loops. Use of several small pumps in a radiant floor system allows each loop to be controlled by a different thermostat. Model SID10 is designed to be powered by a 10 Watt PV module and can pump 2.5 gallons per minute at no head and ½ GPM at 2.5 feet of head at 17 Volt input. Model SID10B is designed to be battery powered and has the same specifications. Inlet and outlet connections are threaded 1/2" NPT male
