Dry-running mechanical shaft seal

Built for extreme conditions
The ESD32T can be equipped with a short-term heat trap for extreme high-temperature applications, ensuring smooth operation even under the most demanding conditions.
It is also available with a debris collection tray, which effectively prevents wear particles from contaminating the tank space.

Minimal leakage, easy monitoring
Thanks to its minimal leakage, this seal is especially well-suited for handling non-critical substances.
No spring preload adjustments are required after installation, which simplifies the setup process.
The unit is easy to monitor, and since it operates dry, there is no need for additional sealant systems or external flush media.

Redundant temperature monitoring and wear indicator
For increased safety and extended service life, the ESD32T is equipped with redundant temperature monitoring via a transmitter.
In addition, a visual wear indicator provides a clear signal when maintenance is required, simplifying the service routine and minimizing unplanned downtime.

Ideal for specialty chemicals and biofuels
This advanced shaft seal is particularly suitable for a wide range of applications, including specialty chemicals, formulated consumer products, storage tanks, and processes within biofuels and biorefineries.
With its versatility and high reliability, the ESD32T ensures effective sealing across a broad range of industries.

Single-acting design with dual sealing rings
The defining feature of single-acting mechanical seals is the use of two sealing rings, creating a single sealing interface with no barrier fluid chamber.
This makes them ideal for dry-running conditions or for processes where the product itself provides lubrication and cooling.

Suited for non-critical media and low-pressure environments
Single-acting seals may allow a small amount of product to escape to the environment, which makes them suitable for non-hazardous, non-critical media and low-pressure applications.
While they do not maintain containment at the level of double or triple mechanical seals, they are the ideal solution for conditions where full sealing integrity is not critical.
