PF02B Mechanical Seal for Paper Pulp Pumps and Flue Gas Desulfurization System.

Structural Features: double end, multi springs, balanced, independent rotary direction, still structure, pin transmission. The still springs are suitable for high operating speed. The springs are separated from the sealed mediums so they will not be jammed. Piston design allows great axial shifting. The seal is cartridge design with easy installation and reliable performance.

Industrial Standards: specific customization.
