CM318A Mechanical Seal

Structural features:

1. Single-face, cartridge-type design with multiple springs, ensuring even pressure distribution across the sealing surfaces. It can be used regardless 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 (the gland itself is equipped with flushing ports, making it easy to cool and flush the seal).

Applicable medium:

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

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 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 contact or tapping 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 a certain degree of flexibility.
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.
