  • Balancing | KSB

    Balancing is a process used to correct the unequal distribution of geometric mass (see Unbalance ). In the case of centrifugal pumps, this is performed in such a manner as to render the rotation axis of the pump's rotor a free axis (no free inertia effects during rotation). A distinction is made between static and dynamic balancing.

  • Pump Rebuilding and Balancing (Part One) | Pumps & Systems

    2011-12-17 · Balancing involves aligning the geometric center with the mass center. The geometric center (manmade) is the center of the rotating shaft and pump impeller assembly. The mass center is the center the assembly tries to rotate around naturally. The pump impeller would spin around this axis if it were thrown through the air like a Frisbee. These two centerlines are never perfectly …
