AUMA is a global manufacturer of electric actuators used in the automation of industrial valves. The global company currently employs more than 2,300 people. Its long-term growth strategy, as well as its well-established financial position, allows it to continuously develop and lead with innovations among manufacturers.

Polinski AMT has been working with AUMA for many years, thanks to the

AUMA actuators are typically used by us for the valves, butterfly valves and gate valves we offer to our customers. We chose this brand of electric actuators because it provides a wide range of applications even in the harshest conditions, and the manufacturer develops its offerings in line with customer needs. AUMA is constantly expanding and entering new market segments and acquiring new brands that produce top-quality equipment:

  • Getriebefabrik Coswig (GFC) joins the AUMA group – subsequently transformed into AUMA Drives – completes the product range with gearboxes for actuators.
  • In 2000. AUMA welcomes into its circle the SIPOS brand, which has more than 100 years of experience in actuators – AUMA SIPOS Aktorik
  • Haselhofer Feinmechanik is also a member of the AUMA group – actuators with special design for industry and marine – AUMA Industry + Marine
  • Since 2008. Since 2008, AUMA DREHMO, a high-quality actuator series also suitable for use in potentially explosive atmospheres, such as the DREHMO i-matic.
  • HALM – Motors + Systems was acquired and the name changed to AUMA Motors + Systems . The business profile remained the same targeting users who need actuators with individual requirements, and made in the highest quality using the latest technology.

The most popular AUMA electric actuators are multi-turn actuators in the basic SA version. These are devices with which we can control various types of valves. Control of the operation of valves responsible for the flow can consist of open-close with casual operation S2 -15 min or versions adapted to S2-30min operation. SA actuators can be controlled by simple controllers or via fieldbus, microcontroller or HART communication protocol.
