Double Mechanical Seal For Pump A42-150 Mechanical seal

Mechanical seal double seal (double end mechanical seal) is an efficient sealing solution, widely used in harsh working conditions. The following are its core advantages and typical application scenarios:

Core advantages of Double Mechanical Seal:

1. Better Leakage Control

The two sealing surfaces arranged in series form the primary and secondary lines of defense. When the primary seal fails, the secondary seal can still maintain sealing, which is especially suitable for toxic, flammable or high-value media (such as liquid hydrocarbons, strong acids).

2. Isolation fluid system efficiency enhancement

The pressurized isolation fluid (such as glycerol or synthetic oil) is injected between the two sealing surfaces, which has both lubrication cooling and pressure monitoring functions.

3. Pollution control advantage

In the food-grade vacuum emulsifier, the double seal structure can prevent the invasion of external microorganisms and maintain a sterile environment in the tank.

Typical application areas of Double Mechanical Seal:

High-risk chemical processes

Energy equipment

Pharmaceutical clean system

Special working conditions
