Coaxial Agitators KOAX

High Performance - For Complex Processes and Extreme Viscosities

EKATO coaxial agitators are high performance units equipped with two universal impeller systems, each with an independent drive system. All kinds of mixing tasks arising in the different process steps such as homogenizing, suspending, dispersing, heat transfer as well as the decomposition of solids, can be combined and performed. This mixing system is preferred for complex mixing processes and products with extreme viscosities and flow behaviors.

Additional Services

Lab tests with the original products can be carried out and analyzed in our highly modern laboratory (ELA lab- and pilot-reactors).Our process specialists will help to put the perfect mixing system together, according to your process requirements. CFD-studies, finite element analyses as well as scaling up to industrial scale, complete EKATO’s range of services.

Standard Design

  • Two interdependent drives and control units which can be driven with different shaft speeds and directions of rotation.
  • Combination of different impeller-systems (for example: EKATO PARAVISC with EKATO VISCOPROP or Dissolver). Versatile modular system which easily adapts to the varying process requirements.
  • Sealing systems from seal rings, stuffing boxes up to latest double-acting mechanical seals for the central- and peripheral shaft

Additional Features

  • Flexible or rigid scrapers
  • Bottom anchor or Z-anchor

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.
