Thanks for your Question. Stefan Fediw, has responded: "There is a limit to the fluid's viscosity when using a centrifugal pump. This limit varies depending on the type of centrifugal pump. In general, after about 600 SSU, centrifugal pumps start to consume large quantities of power. The higher the shear (multi impeller vanes), the more power required at increased viscosities. The other type of pump - positive displacement - generally can handle more efficiently higher viscous fluids." Please call us at 1-877-624-5757 if we can help you with a specific application.
In one part@26:44, pump curve changed due to viscosity changed, while in the example latter, the same pump curve used even viscosity changed?
Does viscosity changed, shift pump or system curve, i see in video example only changed on sysyem curve on unchanged pump curve?
Any info for viscosity effect on axial flow pumps?
So what is disadvantage using centrifugalpump for pumping viscosity fluid? Example honey or tomato sauce/paste.
