Product Details

Dual seals are recommended for a variety of purposes that include:

To prevent a costly product from leaking.
To prevent a dangerous product from leaking to the atmosphere.
To prevent a pollutant from escaping to the atmosphere.
As a back up seal to prevent costly down time when the first seal wears out or fails. This is an important element in any predictive maintenance program.

All of the above are sensible reasons for using two seals in a pump, but In this paper we’ll be considering the use of dual seals as an environmental control to prevent the sealed product from either opening the seal faces, or damaging one of the seal components, the two reasons any mechanical seal ever failed.

We can use the dual seals to:

Control the temperature at a seal face.
Prevent a pressure drop across a seal face.
Eliminate atmospheric conditions outboard of a mechanical seal.
To break down the pressure in a high pressure application, by inserting an intermediate pressure between the seals. Two lower pressure seals can then be used to seal a high pressure fluid that would normally require a very expensive high pressure mechanical seal.
To provide a lubricant if one is needed to prevent “slip stick“. This is almost always the case when you are sealing a gas.

Dual seals can be of either the rotating or stationary version and can be installed in four different configurations.

Back to back or facing in opposite directions
Tandem or facing in the same direction
Face to face or facing towards each other
Concentric or one inside the other.

The fluid that circulates between the seals is called barrier fluid if it is higher than stuffing box pressure. It is called buffer fluid if it is lower than stuffing box pressure. It can be circulated between the two seals by:

Natural convection using a convection tank. Insulated piping coming from the top of the gland to the convection tank, and finned piping coming out of the tank will aid convection if heat removal is a problem.
A pumping ring can be installed between the seals for those instances where natural convection is not sufficient to remove the heat being generated between the faces. This is very necessary when oil is used as the barrier fluid. Oil has a low specific heat and poor conductivity, making it a poor choice as a barrier fluid. Most of the newer cartridge dual seals come equipped with a built in pumping ring.
Introducing the fluid between the seals, from an external source. Be sure to bring the fluid in at the bottom of the gland and out the top to prevent an air pocket from forming in the gland.

The following illustrations describe the rotating version (the spring or springs rotate with the shaft) of these dual seal configurations. You should be aware that a stationary version is also available from any of the major seal companies. You should also consider:

Use only the hydraulically balanced version of these seals to prevent the generation of excessive heat between the seal faces.
Two way balance is always desirable in any dual seal application to allow you the option of using either a high or low pressure barrier fluid and to prevent the seal faces from opening if either the system or the barrier fluid pressure fluctuates.
Be sure to select seal faces with good thermal conductivity.
Try to locate any elastomers away from the seal faces if possible. Elastomers are very sensitive to heat.
