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.
