We have already supplied large agitators with a drive power of up to 3,000 kW, shaft lengths of more than 15 m, as well as shaft diameters of 500 mm. These agitators have been designed to ensure maximum operational safety and comply with all valid DIN standards as far as possible. The robust design, as well as the easy and quick replacement mechanical seal, guarantee minimum maintenance costs and low operating costs

Drive versions with fixed or variable shaft speeds and different types of gearbox (flat, beveled, helical …)

Optional cast and welded flashlights

Quick replacement of the seal through system for this purpose (without the need to uninstall reducer and motor):

Industrial Agitators EM

EKATO agitators are designed for a wide range of volumes, and for pressurized or non-pressurized recipients. The unit can also be driven directly by an engine or together with a reducer. It is also possible to connect the motor via an IEC connector or a gearmotor. The shaft can be sealed by a mechanical seal or other types of seals.

KOAX Coaxial Agitators

EKATO coaxial agitators are high performance units equipped with two universal impeller systems, each with an independent drive system. All types of mixing tasks that arise in the different stages of the process, such as homogenization, suspension, dispersion, heat transfer as well as solids decomposition can be combined and accomplish. This mixing system is preferred for complex processes and products with extreme viscosities and flow behaviors. Therefore, stages with different viscosities can be processed, from aqueous substances to 1 million mPas. KOAX agitators are a cost-effective alternative to mixers and extruders.

ESM Magnetic Safety Agitators

The EKATO magnetic safety agitator prevents leakage of the product by using a hermetic seal between the product and the environment, even when the agitator suffers some type of breakdown, which makes it the most suitable for mixing dangerous materials.

Compact Agitators FD/KD/HWL-A

The EKATO FD, KD and HWL compact agitators are available for open or with low pressure vessels. Its robust design and excellent softness when operating make them extremely reliable, even when mixing media with a high solids content. Other advantages are the low total height and the modular design that guarantees low cost maintenance and easy operator modification, if necessary.

Impellers

Highly Efficient Impeller Systems Developed For Individual Requirements In Mixing Technology

In recent years, the requirements for mixing systems in industrial applications have increased steadily. The design of the impellers, the selection of a suitable mixing system, as well as the arrangement of the individual components on the agitator have a decisive influence on the process engineering and mechanical properties.

This not only applies to the agitators but also the reactors and their components. The comprehensive optimization of conventional impellers with industry-specific aspects was the basis for the development of the EKATO impeller family which is continually setting new standards in the field of mixing technology.

Mechanical Seals for Agitators

Wide range of seal technology for various applications

In mixing technology, the sealing of a rotating agitator shaft in the passage through a vessel wall represents the principal sealing task. Different sealing principles are used depending on operating conditions such as pressure, temperature, and speed.

Since 1950, mechanical seals have been used in agitator technology. EKATO is one of the pioneers in the use of mechanical seals in agitators and continue to produce them today.

In the sealing technology of EKATO, single-acting, double-acting, and triple-acting mechanical seals are used. A further distinctive feature is the type of seal lubricant. A distinction is made between dry running and gas- and liquid-lubricated mechanical seals.

Most mechanical seals of agitators consist of two rotating and two stationary slip rings (i.e., two pairs of slip rings). These pairs of sliding rings form a closed space, the seal chamber, which can be filled with a liquid, the seal liquid. By pressurizing the seal liquid, it is possible to ensure that the vessel contents are safely separated from the surroundings. When the seal chamber pressure is controlled to be always higher than the vessel pressure, the inevitable leakage of the seal liquid through the sliding surfaces can only enter the vessel or the surroundings via the sliding ring pair on the atmospheric-side.  Conversely, the mixing product might not be suitable for the mechanical seal.

EKATO has a wide range of robust seals and reliable accessories for cooling and supplying the seal with seal medium. This makes it possible to flexibly perform sealing tasks and find the best solution for all sealing challenges. EKATO seals and their supply are thus always adapted to the specific application as well as the requirements of the customer.

Mechanical seals also have safety functions. EKATO therefore always tests the function of a sealing system before delivery. All the important operating data (e.g., speeds, temperatures, pressures, flow rates, filling levels, and leakage quantities of seal liquid and cooling water) can be continuously recorded electronically and submitted to the customer in the form of an inspection report.

This makes it possible to flexibly tackle sealing tasks such as:

• Tank temperatures from −60 to 400°C
• High pressures up to 200 bar
• Extreme sterility
• Batch/continuous operation
• Long service life
