ELECTRIC ACTUATORS for continuous underwater use

The SA multi-turn actuator for continuous underwater use by AUMA opens new applications for electric actuators – for water supply, in hydropower plants and underwater valves in general. Easy installation, low operating costs and maintenance requirements as well as the comprehensive functions of the integral actuator controls – to name only some advantages of electric actuators, turning them into a true solution for underwater applications. TIGHTLY SEALED  A sophisticated sealing system combined with excellent corrosion protection properties qualify AUMA actuators for underwater use. Double sealed...

In in run-of-the-river power plants (ROR), used to exploit the energetic potential of water courses with low gradient levels, variable speed electric actuators are deployed for starting, synchronisation and stopping of turbines installed completely under water. In screen cleaning systems, retaining twigs and other solid foreign objects from the turbine inlet, electric actuators for underwater use are installed for ecological and economic reasons. The variable speed version enables soft and gentle approaching of end positions. Applications in water management Where both supply and sewer pipes...

DESIGN Electric SA multi-turn actuator AUMA SA multi-turn actuators are available in many sizes and versions and can be tailored to the individual requirements of the application. They are characterised by easy operation, robust design, reliability and a long service life. These properties are indispensable for continuous underwater use. In addition, actuators for continuous underwater use are subject to a comprehensive sealing scheme, preventing the ingress of water efficiently for several years. A handwheel is available as option for sizes 07.2 – 16.2. 1 MWG electronic control unit for non-intrusive...

SERVICE CONDITIONS AC integral actuators controls AC actuator controls are mounted separately outside the water while cables connect them to the actuator. The state-of-the-art actuator controls assume communication control between DCS and actuator. Actuator controls are available with various interfaces to the DCS – allowing both parallel signal transmission and fieldbus communication. Supported are among others Profibus DP and Profinet, Modbus RTU and TCP/IP, Foundation Fieldbus as well as HART and WirelessHART. Integral local controls also allow for direct actuator operation. Advanced diagnostic...
