    About the Pump Shaft Material Selection In Boiler Water Pump

    Jackelmo: A very common shaft material (and the one we always use) for boiler feed pumps is 410 SST Cond T. This may be cheaper and readily available than the one you are considering (A276 S42000). In case you haven't bought your shaft material, you can get a quote for 410 SST Cond T. Just my 2...
