AUMA Actuators Limited provides underwater electric actuators engineered for permanent submersion and flood-prone environments.
Designed for critical infrastructure applications, these actuators deliver precise valve control, intelligent diagnostics, and long-term reliability even when operating fully underwater.
Actuators maintain full functionality even when submerged, ensuring uninterrupted valve control.
Integrated controls provide operational data and diagnostics for predictive maintenance.
Marine-grade materials and coatings protect against aggressive environments.
Electric actuation eliminates the need for hydraulic systems and associated maintenance.
AUMA underwater actuators are designed to maintain sealing integrity and mechanical reliability under prolonged immersion.
Core Design Features
Permanent submersion capability – tested to IP68 and beyond
Operational depth capability – up to 30 metres
Double-sealed enclosure system – protects internal components during operation and servicing
Pressure compensation system – maintains internal pressure balance at varying depths
Corrosion-resistant construction – marine-grade materials for harsh environments
ATEX-compliant protection for underwater and intermittently flooded environments with methane-producing organic matter.
Built for Critical Infrastructure Applications
These applications require reliable actuator performance in environments where maintenance access may be limited.
Replacing hydraulic or pneumatic systems with electric underwater actuators simplifies infrastructure and reduces long-term operating costs.
