Swivel Side-Entry Agitator ES-SW

Swivel Side-Entry Agitators for Oil-Storage Tanks

EKATO ES-2000-SW agitators with mechanical seal are designed for storage tanks of different sizes. The shaft is sealed by a single-acting product lubricated or double-acting liquid lubricated mechanical seal according API 682, modified for agitators. Manual swiveling or optional automatic adjustment control via DCS is available. The agitator is equipped with a device to ensure quick and easy maintenance or replacement of the seal, while the vessel is still filled up

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.
