LOOK AT THE BIGGER PICTURE: HOW SEALS AFFECT CENTRIFUGAL PUMPS

Bearings play vital roles in centrifugal pumps by supporting the mass of the impeller and rotating shaft, the hydraulic loads imposed on the impeller, and loads due to couplings and drive systems. They further keep axial and radial deflections of shafts within acceptable limits for the impeller and...

Description
Summary:Bearings play vital roles in centrifugal pumps by supporting the mass of the impeller and rotating shaft, the hydraulic loads imposed on the impeller, and loads due to couplings and drive systems. They further keep axial and radial deflections of shafts within acceptable limits for the impeller and shaft seal. Ultimately, the service life of bearings will directly impact the reliability and service life of a centrifugal pump.
