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. ...

Use a small, inexpensive PV module (photovoltaic panel) to power the pump. No battery or electronic controller is used. There is no wiring to the building's electric system.

Sun-synchronous operation: pump speed varies with sunlight, corresponding to the available heat in the collector - natural automation!

This principle has proven highly reliable in solar water heaters since the early 1980s. For hydronic heating (using battery system). Power requirement is less than half that of ...

Low power, low pressure pumps circulate liquid in closed loop heating pipes. Hot water from solar water panel, wood stove or propane water heaters can be used to heat floors, radiators, and even circulate water under water beds and compost toilets. 1/2" threaded fittings.

Use several small pumps, one for each zone rather than zone valves and a bigger pump. DC circulating pumps use much less power than AC pumps, just 18 to 50 watts. These can be powered from batteries, or direct from a solar ...

March’s proven magnetic drive eliminates the troublesome, old-fashioned shaft seal. There can be no seal wear, power-robbing friction or leakage through the seal. Impeller and drive magnets are permanent ceramic type. They prevent slippage and insure that full motor horsepower is converted into pumping power.

Energy requirements are lowered, as all the energy produced by the motor is utilized, especially important in solar systems.

March seal-less drive also provides for faster, ...
