Prediction of the dynamic forces acting on a shaft

By means of flow simulation, engineers from Sulzer Pumps and Sulzer Innotec have been able to show that a modified pump sump geometry can lead to significantly smoother and uniform inflow at the pump inlet. The radial forces acting on the shaft can therefore be reduced and mainly centered around the zero point, allowing a significant increase in the lifetime of the bearings.
