Electric actuators for continuous underwater use
A new version of AUMA’s SA and SAEx multi-turn actuators is suitable for continuous underwater use, including water supply systems, hydropower plants, and civil engineering constructions for water applications. A universal sealing system combined with comprehensive corrosion protection qualifies these actuators for underwater use. Double-sealed cable glands at the electrical connection, inner seals - some in pairs - on all housing covers, and a one-piece solid shaft effectively prevent the ingress of water. The actuators are qualified for up to 15 m head of water, with higher heads of water available on request. Torques from 10 Nm to 1,000 Nm are covered.
