AUMA - modular actuators from engineering experts

Paul Boughton

Established in 1964, AUMA has expanded to gain a presence in all continents and the international organisation includes 20 subsidiary companies. The AUMA group has 1,700 members of staff. 900 people are employed at the company’s prestigious German R&D and production headquarters, which is over 12,000 sq ft.

Typical applications are water and wastewater treatment plants, conventional and nuclear power plants, tank farms and gas transfer stations as well as civil and military vessels

AUMA is a competent partner offering expertise for local applications in any location around the globe.

The AUMA portfolio of modular actuation products includes:


  • multi-turn actuators
  • part-turn actuators
  • linear actuators
  • lever actuators
  • controls
  • multi-turn gearboxes
  • part-turn gearboxes
  • linear gearboxes
  • lever gearboxes
  • test equipment


AUMA Launches Generation .2

The new Generation .2 multi-turn actuator range SA 07.2 – 16.2 and new actuator controls AC 01.2 have been launched by AUMA: the products will be ready for order and delivery from first quarter 2010. Designed to cater for existing market needs, and next generation requirements, capabilities include the integration of field devices into Asset Management Systems. AUMA has introduced a number of enhanced features and expanded the functionality of its range, while retaining proven design principles.


The devices, both actuators and controls, are fully compatible with AUMA’s previous products: this ensures low-risk investment and guarantees that the company will always be at the forefront of technological development. Mechanical enhancements include:

  • improved positioning accuracy
  • the output speed range of modulating actuators
  • extension of the expected actuator lifetime
  • enhanced corrosion protection


AUMA’s innovative product developments are the result of an intensive exchange between valve manufacturers, consultants, plant operators and control/communication system manufacturers. It was recognised that standards should be followed as closely as possible for all developments outside of the products’ new intelligent functions. For example, the status signals of the AC 01.2 are classified in compliance with NAMUR recommendation NE 107. Consequently, the plant operator receives clearly interpretable signals from the actuators and all other field devices and new diagnostic features of the actuators are supported.


Temperature/vibration sensors and applied torque recording are used to continuously monitor all parameters which contribute positively to the actuator’s life. If an actuator is operated outside the specified operation conditions, for example with an impermissible high number of starts, the plant operator receives advance information enabling appropriate action to avoid malfunction.


In line with AUMA’s previous products, the new controls are available with different fieldbus interfaces, including the Profibus DP interface with V2 services.
