Note: Since pumps serve a variety of purposes, the sealing materials (friction pairs) also differ. To ensure reliable sealing performance,
The manufacturer recommends the following:
1. Clean oil (particle-free conditions) – The dynamic ring friction pair is made of alloy, while the stationary ring friction pair is made of graphite.
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 areas 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 thin 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 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.
