CM318I Mechanical Seal

Structural features:

1. Single-face, cartridge-style design with multiple springs, ensuring even pressure distribution across the sealing surfaces. Operation is independent of the rotation direction.

2. Depending on the specific application, auxiliary sealing rings can include rubber O-rings, PTFE V-rings, or PTFE wedge-shaped rings.

3. The modular mechanical seal replaces the packing seal without requiring any equipment modifications.

Applicable medium:

Oil, water, acids, bases, salts, and more

Work parameters:

Fixed substance content: ≤20%

Warm Temperature: ≤280°C

Press Force: ≤3.0 MPa

Axis Diameter: ≤200mm

Material parameters:
Main material: 304, 316L or 2205, 2507, 1.4529
Sealing ring materials: M106D, YWN8, SSiC or SiC
Rubber materials: Fluororubber or perfluoroether rubber

Main applications:

This seal can be used in various types of water pumps and chemical 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 area 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, ensure that the screws are tightened evenly to maintain perpendicularity between the stationary ring face and 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 rotate the shaft—there should be no sensation of unevenness or heaviness.
8. Before starting operation, the equipment must be fully charged with the medium to prevent dry friction, which could lead to seal failure.
