How Do We Decide on Single-Plane, Two-Plane, or Multi-Plane Balancing?

The dynamic balancing requirements of the workpiece or end-user specifications determine the number of balancing planes needed. Generally, if the part length is greater than its diameter, two-plane balancing is used. Disk-shaped parts, such as flywheels and pump rotors, can be balanced in a single plane. For complex parts like multi-stage pumps or turbines, multi-plane balancing is preferred.
