AUMA manufactures a complete range of actuators suitable for installation in hazardous locations. Explosionproof actuators are designed in such a way that a flame or spark cannot reach the outside of the actuator enclosure. AUMA explosionproof actuators are available for applications requiring multiturn, quarterturn (part-turn) and linear actuation.

Hazardous location requirements

AUMA offers actuators in accordance with several international standards including ATEX, CSA and FM. The FM version meets the following criteria:

  • Class I, Division 1, Groups C & D
  • Class II / III, Division 1, Groups E, F & G

  • Suitable for requirements up to 103,000 lb thrust / 2960 ft lb torque direct mount and 309,000 lb thrust / 11,800 ft lb torque in multiturn actuator / bevel gear combinations.

Quarterturn actuators

  • Single-phase quarterturn actuators up to 880 ft lb torque
  • Three phase actuators of both the SGExC and SAExC / GS types are capable of 265,000 ft lb torque.

Linear actuators

  • Appropriate for applications requiring up to 48,825 lb thrust at strokes up to 19.6 in.

Broad range of features

  • A wide range of operating speeds and closing times is available.
  • Versions are available for both open/close and modulating service.
  • Enhanced submersion and corrosion protection options are available to deal with unusual or adverse environmental conditions.
