Pilot Plant ELA 50

Process Development Plant for Highly Viscous Applications

ELA 50 is a pilot plant for process developments in a 50 l scale and is preferably used for highly viscous applications. It comprises a reactor with a coaxial agitator system which allows operation of a central and a close-to-the-wall impeller. A vacuum station can be used for degassing and solvent recovery. These units are installed in an EX-proof area and suitable for operation with flammable liquids. Processes are investigated under well defined fluid dynamic conditions

What does “Number of sealing faces” mean?

Single-acting mechanical seals
These seals have one sealing surface and only seal in one direction. They are generally simpler in design and are commonly used in applications where pressure is applied from only one side.

Double-acting mechanical seals
These seals have two sealing surfaces and can seal in both directions. They are ideal for applications where pressure may come from both sides or where a higher sealing performance is required.

Triple-acting mechanical seals
These are less common and used in specialized applications that require a more complex sealing setup. They offer additional sealing surfaces or mechanisms to ensure reliable sealing even in highly demanding environments.
