Fresh & Waste Water Applications

Brunel Safety Element Torque Limiters have been protecting industrial power transmission systems around the world since 1971.

The Waste Water Safety Element “SE” Series Torque Limiters are designed specifically for the outdoor, corrosive “waste water” environment. They are made of 316 stainless steel throughout with the exception of D-2 ( Rc 62) tool steel “ working parts” in the safety element, “O” ring seals and PTFE bearings. The internal parts are packed with grease and are externally regreaseable. Eight “O” ring seals prevent contaminants from entering the unit while a grease vent allows added grease to escape. Modular construction provides design flexibility and simple maintainability.

Safety elements are precision Belleville spring loaded, single ball detent design. A unique over-center mechanism ensures complete and bidirectional disengagement on overload and simple, fast manual re-engagement. Four types of Safety Elements: standard, disconnectable, externally adjustable and externally adjustable disconnectable are available and are interchangeable on the base unit.
