Structural features:

Single-end cartridge mechanical seal. Easy to install and simple to use. Balanced design, with optional rotation direction.

Internal working length is short. The stationary ring features multi-spring external compensation that does not come into contact with the medium.

Applicable medium:

Medium containing high levels of impurities such as gypsum and lime slurry.

Work parameters:

Fixed substance content: ≤30%

Warm Temperature: ≤280°C

Press Force: ≤2.5 MPa

Axis Diameter: ≤220mm

Material parameters:
Main material: 316L or 2205, 2507, 1.4529
Sealing ring material: SSiC or SiC
Rubber materials: Fluororubber or perfluoroether rubber

Main applications:

This type of mechanical seal is primarily used in flue gas desulfurization systems for coal-fired power plants, and is suitable for absorption tower slurry circulation pumps, gypsum slurry pumps, limestone slurry pumps, and gypsum discharge pumps.

Installation Use Requirements :

1. The radial runout of the equipment shaft should not exceed 0.04 mm, with axial runout not exceeding 0.1 mm;
2. The sealing cavity areas of the equipment should be kept clean during installation, and sealing components must be thoroughly cleaned. Ensure that the sealing end faces remain intact to prevent contaminants and dust from entering the sealing area.
3. During installation, avoid any impact or hammering to prevent damaging the mechanical seal through friction, which could lead to sealing failure.
4. During installation, apply a layer of clean machine oil to the surfaces that will come into contact with the seal, ensuring smooth installation.
5. When installing the stationary ring gland, tighten the screws evenly to ensure the stationary ring face is perpendicular to the shaft centerline.
6. After installation, gently push the moving ring by hand to ensure it moves freely along the shaft while maintaining some elasticity.
7. After installation, manually turn the shaft—there should be no sensation of unevenness or heaviness.
8. Before operating, the equipment must be fully charged with the medium to prevent dry friction, which could lead to seal failure.
