Compact Agitators FD/KD/HWL-A

Agitators Designed for Open or Low Pressure Vessels

The compact EKATO agitators FD, KD and HWL-A are designed for open vessels or those which have a low pressure. Their robust design and excellent smoothness when operating make them extremely reliable, even when mixing media with high solid contents. Further advantages are the low overall height and the modular design which ensure maintenance at low cost and an easy modification of the agitator, if necessary.

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.
