Background Knowledge：

Why double or dual mechanical seals are recommended in most cases

Double or dual mechanical seals are designed for maximum sealing safety. These seals essentially eliminate leakage of the fluid or gas being handled in mixers or pumps.

*Double seals provide a level of safety/zero emissions compliance not achievable with single seals. This is essential when pumping or mixing a dangerous or toxic substance.

*Double seals are a must-have for certain applications in many countries

*These seals are increasingly used by companies to meet specific environmental goals or emissions requirements.

*A properly installed double seal also allows for near-complete control over the seal operating environment and fluid film over the seal faces. This factor alone can greatly maximize seal life.

How It Works

A double mechanical seal has two primary seals with a barrier or buffer fluid area in between. Each primary seal typically consists of a softer, narrower stationary face accompanied by a harder, wider rotating face. This arrangement enables the softer seal to wear while maintaining the integrity of the harder faced seal during service.

When to Use Double Seals

Pump and seal manufacturers recommend double seals for a variety of reasons:

*Prevent a hazardous product from reaching the atmosphere/polluting the environment

*Avoid leakage of an expensive process fluid product

*Maximize seal life by controlling the type of fluid film on the seal faces

*Isolate the mechanical seal from atmospheric conditions

*Provide an alternative when the process fluid will not provide stable and reliable lubrication of the seal faces (such as gaseous media, viscous fluids, non-settling slurries, or fluids liable to harden)

*Establish a backup seal in the event of an inboard seal failure or planned equipment repair (or to identify seal failure during operation)

*Avoid contamination of the process media should one seal fail

Full Control Over the Seal Environment

To extend the life of any seal, you want to control the fluid film that comes into contact with the seal face. This establishes the ideal lubrication, temperature, and pressure. A dual seal allows you to control of all these factors.
