Shaft Breakage

Breakage from high radial loads occurs at several places:

  • Double suction or multistage pumps usually break their shaft about mid point of the shaft span.
  • Single suction, end suction centrifugal pumps break their shafts at the shoulder where the hub joins the sleeve.

You can calculate the hydraulic force on your shaft if you refer to: Shaft bending, S040
