CM1 CM1B Mechanical Seal

CM1 CM1B Mechanical Seal

Structural features:

1. Single-faced, Set The transmission features evenly distributed force across the multi-spring sealing surfaces. During operation, it is independent of the rotation direction, and the spring seat, springs, and thrust ring can be pre-assembled into a single unit for convenient installation.

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

3. Complies with ISO 3069, DIN 24960, and GB 6556 standards, offering excellent versatility.

4.CM1B Type is CM1 A balanced structural design suitable for higher-pressure operating conditions.

Applicable medium:

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

Note: Since this type of pump has multiple applications, the sealing material (friction pair) also varies. To ensure reliable sealing performance,
The manufacturer recommends the following:
1. Clean water (without particulate matter)—Choose an alloy for the dynamic sealing pair and graphite for the static sealing pair.
2. Highly corrosive environments (conditions involving particulate matter) – For the dynamic seal pair, select silicon carbide; for the stationary seal pair, also choose silicon carbide.
3. Conditions involving particles and significant vibration—select (alloy) for the dynamic ring friction pair, and (alloy) for the stationary ring friction pair.
4. Customization is also available upon customer request. If no specific request is made, the default option will be (clear water).

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 of the equipment should be kept clean during installation, and sealing components must be thoroughly cleaned. Ensure that the sealing 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 starting operation, the equipment must be fully charged with the medium to prevent dry friction, which could lead to seal failure.
