12 volt battery based high speed hot water circulation pump.  Low power, low pressure pump 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 or radiators, and even circulate water under water beds and compost toilets.  Use several small pumps, one for each zone rather than zone valves and a bigger pump.  A closed loop system with no air pockets is balanced and has no head requirement for pump except pipe friction.

1/2" threaded fittings.

Draws up to 4.0 amps.  Maximum flow of 6.5 gallons per minute at no head.  Maximum unbalanced head of 15'.

March pumps are centrifugal low pressure, no valves or diaphragm to wear out. Water contact parts are brass. No shaft coupling or seal to leak because magnets couple the motor to impeller right through the solid brass housing. Fluids can be as hot as 250 degrees F. PRE-2009 models M809 motor brushes last 10,000 hours.The M809HS motor brushes last 7500 hours. As of 2009, these March pump motors NO LONGER have replaceable brushes. The motor manufacturer claims the new motors should last 30,000-40,000 hours. Just to be clear, these motors DO have brushes but the brushes cannot be replaced.

One year warranty.
