Advantages of Bellows Seal

Friday 28th August 2020

Let's take a look at the advantages of using a Bellow Seal instead of a Mechanical seal.

Advantages of a Bellows Seal

There are a couple of advantages to having a bellow seal instead of the standard mechanical seal. Filton use a Bellows seal within all their standard Rotary Unions, the operating temperature range can be between -20⁰C to +300⁰C.

The advantages are;

-        A Bellows seal does not require an elastomeric ‘O’ Ring which can limit the operating temperature and chemical compatibility. 

-        A Bellows seal does not have any moving parts with close clearances which could seize due to corrosion or debris within the system.
