Basic types
Mechanical seals for pumps are divided into seven basic types Type: 103: built-in single-end single spring unbalanced and spring-driven mechanical seal, see Figure 1; b.
B103: built-in single-end single spring balanced and spring-driven mechanical seal, see Figure 2; 104: built-in single-end single spring unbalanced sleeve drive, see Figure 3: its derivative 104a is shown in Figure 4; B104: built-in single-end single spring unbalanced sleeve drive, see Figure 5; its derivative B104a is shown in Figure 6105: built-in single-end multi-spring unbalanced screw drive, see Figure 7; B105: built-in single-end multi Spring balanced screw drive, see Figure 8; Type 114: external single-end single spring over-balanced dial drive, see Figure 9. Its derivative type 114a is shown in Figure 10.3.2 Main dimensions
Type 103 see Table 1;
Type B103 see Table 2;
Type 104 see Table 3, Type 104a see Table 4;
