Mechanical shaft seal for flue gas desulfurization (FGD)

Efficient product-based lubrication and cooling
A key advantage of the ESD42 is that it uses the liquid product itself for lubrication and cooling, eliminating the need for additional hydraulic or flushing systems.
Its special polymer construction offers enhanced resistance to clogging and corrosion, resulting in extended service life and lower maintenance requirements.

Seal replacement during operation – no tank draining required
One of the standout features of the ESD42 is its ability to be replaced while the system is in operation, without draining the tank.
This significantly reduces downtime and boosts productivity, which is especially important in continuous-process industries.

Specifically designed for FGD applications
The ESD42 is ideally suited for use in flue gas desulfurization systems, where seal reliability is essential for maintaining safe, efficient, and environmentally responsible operations.

For low-pressure applications and non-critical media
As a single-acting seal, the ESD42 may allow minimal product leakage to the surroundings. This makes it well-suited for sealing non-critical substances in low-pressure environments.
While it does not offer the sealing integrity of double or triple mechanical seals, it is ideal for applications where absolute containment is not required.
