"What are unbalanced shapes and balanced shapes? What do they mean?" Let's explain that question! We will introduce their characteristics and more.

This document provides information about the 5th Mechanical Seal Beginner Course, addressing the question, "What are unbalanced and balanced types?" Mechanical seals are selected based on fluid pressure conditions: "unbalanced mechanical seals" for low-pressure conditions and "balanced mechanical seals" for high-pressure conditions. The distinction between unbalanced and balanced types is determined by whether there is a step on the rotating shaft.
