the little things make the difference

JUCHHEIM has a wide portfolio of stirrer drives, stirrer elements, stirrer feedthroughs, and accessories that enable optimal adaptation of this important function to the specific application.

JUCHHEIM agitators are used in the fields of chemicals, biotechnology, pharmaceuticals, cosmetics, paints and coatings, plastics, biofuels, waste water, basic materials, foodstuffs, mineral oils & fats, paper and pulp, and metal processing.

Depending on the application, different designs are required. Agitators in ATEX design allow the use in explosive environments.


numerous geometries. We also manufacture individually according to your specifications.

Stirring couplings

Magnet, O-ring or sliding ring.

Agitator drives

From simple motor to torque measurement and ATEX compliance.


Shaft couplings, contact protection, baffles and more


the little things make the difference

In addition to the standard stirrer shapes, JUCHHEIM also manufactures any stirrer geometries made of stainless steel or Hastelloy® according to your requirements.

The stirring elements or stirring blades can be provided with a PTFE or tantalum coating if required.

For wall-mounted stirrers, we also supply them with wipers made of PTFE or PEEK. These can be easily replaced after possible wear.

We also have gassing stirrers in our program, e.g. for hydrogenation. We are also happy to carry out preliminary tests on our premises. 

We manufacture all stirrer geometries for both cylindrical and conical stirrer vessels:

stirring feedthroughs

stirring couplings, stirring caps

JUCHHEIM Stirring feedthroughs (also called stirring seals or stirring couplings) are a key component of a pressure or vacuum reactor. They are the first to make it possible to stir even in a pressure-bearing vessel, as they seal the rotating shaft or transmit the torque through the wall with strong magnets.

Wherever possible, we recommend a magnetic coupling for use in stirred tanks for process development or process optimization. Only this offers the unique advantage of a purely statically sealed system. However, for large vessels (approx. > 50 liters) or viscous media (approx. > 10 Pas) the transmittable torque can be limiting.

Our magnetic stirrer couplings transmit torques up to 32 Nm at up to 200 bar overpressure and 350°C working temperature. On request, we can also offer models for higher torques, which we can procure with the help of suppliers. Variants for high pressure and high temperature applications are also possible.


inexpensive and robust solution up to 25 bar


Statically sealed system, torque transmission up to 64 Nm

Sliding ring

Mechanical seal complete system up to 50 bar

Accessories / Service

Shaft cardan, contact protection and more

By the way: There are no limits regarding the connection dimensions. We are also happy to adapt our standard systems to your existing system.

 The stirrer caps are manufactured in stainless steel (1.4571 or 316Ti) or Hastelloy.

The inexpensive solution up to 25 bar.

Agitator shaft coupling with O-ring.

Highest torque possible since transmitted directly via the shaft. The stirrer seals with O-ring or mechanical seal transmit several 100 Nm, depending on the model. 

... and tight. With magnetic torque transmission.

From small to large. A few Ncm to 100 Nm. Can be used up to 350°C internal tank temperature thanks to integrated water cooling. Up to 200 bar, depending on the model. These systems do not require any lubricants at all. The replacement of the plain bearings is done in a few minutes.

Low maintenance and clean. Wet mechanical seal systems.

Mechanical seals made of graphite or silicon carbide (SiC) with integrated circulation cooling system (no additional peripherals required) also for GMP applications. Up to 50 bar.

stirrer drives | motors

the little things make the difference

Our stirrer drives are equipped with continuously variable mechanical gears or electronic speed control. The electronic version can be controlled via an automation system.

The stirrer drives can optionally be equipped with torque measurement, which provides a torque-proportional signal for the automation system. This signal is very useful for tracking the course of the reaction and detecting reaction phases in polymerizations, for determining dissipation in the reaction calorimeter and for determining rheological material properties. In addition, the torque measurement is an essential parameter for scale-up experiments.
