Many sectors of industry use mixers and agitators. The blended, mixed or combined materials can vary significantly, e.g. chemicals or minerals. The processes and ambient conditions can also be very different. Our portfolio of high-torque and robust X series industrial gear units is designed to meet your requirements.

Regardless of whether the mixer or agitator is set-up outdoors or inside a building: our gear units function flawlessly, even under extreme ambient temperatures and at high operating temperatures.

It doesn't matter whether the gear unit is installed vertically (on the tank) or horizontally (on the side of the tank), or even under the tank in special cases: we provide the required torque. We also deal with difficult installation conditions: the invertible housing makes universal mounting positions possible. It enables both left and right positions with a single industrial gear unit. This provides flexible application opportunities and the universal housing guarantees the rapid availability of this drive unit – worldwide.

Reliable drive solution for aerators: X series industrial gear units

As a leading manufacturer of industrial gear units, our distinctive modular system technology and large range of optional equipment ensures a reliable drive solution for your aerator. Aerators are used in downstream treatment of waste water in sewage treatment plants, as well as for many other applications. In this case, air circulates through the liquid or substance. In some aerator designs the load and the weight are divided between the gear unit output bearing and the support bearing. Our X series industrial gear units are also the perfect solution for these requirements.

Your benefits

  • Reliable package solution

    thanks to perfectly compatible components and other options that can be combined for your specific application.
  • Reduced expenses

    due to the extended bearing distance concept, which means that you save on the need for a separate agitator bearing.
  • Increased operating life

    as the mechanical seal remains intact for longer due to the reduced tendency to vibrate.
