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.
Valves installed below the waterline or in flood-risk environments require specialised actuation technology. Standard actuators may suffer from water ingress, pressure imbalance, or corrosion that can compromise operation.
AUMA underwater actuators are engineered specifically to ensure:
Continuous operation in submerged conditions
Reliable sealing and pressure stability
Remote monitoring and control capability
Long-term reliability in harsh environments
This ensures critical flow control systems remain operational when they are needed most.
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.
These features ensure long-term durability and dependable performance in submerged installations.
Each actuator includes an integrated Actuator Control Unit (ACU) providing advanced automation capabilities.
Operational data can be accessed through plant control systems or remote interfaces.
These features ensure long-term durability and dependable performance in submerged installations.
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.
Operational Advantages
AUMA actuators are also modular and serviceable, extending product lifespan and supporting circular economy asset management strategies.
Underwater actuators from AUMA combine robust mechanical design with advanced automation technology developed by AUMA Riester GmbH & Co. KG.
This expertise ensures dependable actuator performance across mission-critical infrastructure projects worldwide.
