IHF50-32-125, IHF65-50-160, IHF80-50-200, IHF100-65-200 mechanical seals

Structural features:

1. Single-ended design with PTFE bellows compensation, offering excellent corrosion resistance. When in use, the spring direction does not matter.

2. The auxiliary sealing ring is made of PTFE.

Applicable medium:

In clean water containing oil, water, acids, alkalis, salts, as well as in wastewater and oily effluents with suspended particles.

Work parameters:

Fixed substance content: ≤10%

Warm Temperature: ≤180°C

Press Force: ≤1.5 MPa

Axis Diameter: ≤100mm

Material parameters:
Main material: 304, 316L or 2205, 2507, 1.4529
Sealing ring material: Graphite, silicon carbide, tungsten carbide

Main applications:

This type of mechanical seal is primarily used in various types of water pumps, chemical pumps, sewage pumps, wastewater pumps, and sludge oil pumps.

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. Strong acids and bases (without particulate conditions) – For the dynamic ring friction pair, select (graphite); for the static ring friction pair, choose (ceramic).
2. Strong acids and bases (in conditions involving particulate matter) – Select the dynamic ring friction pair made of silicon carbide, and the stationary ring friction pair also made of silicon carbide.
3. 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 end faces remain intact to prevent contaminants and dust from entering the sealing area.
3. During installation, avoid any knocking 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 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.
