Hardy Taco 009 Stainless Cartridge Pump / Direct OEM Replacement of # 502.50

New stainless steel (ss) circulating pump for Hardy wood furnace. Be aware that the manufacturer now installs the ss pump on all it's assemblies due to problems with electrolysis and the reduction of the life span of the entire assembly caused by the cast pumps previously installed (red and green). The only recommended pump for the Hardy furnace is the stainless pump. Don't reduce your furnace life span by saving $100 (or less) on a pump! Unit carries full one year Hardy warranty.
