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 (Re 62) tool steel "working parts" in the safety elements, "0" 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. 

Three types of safety elements; standard, disconnectable, and externally adjustable are available and are interchangeable on the base unit.

Safety Element Torque Limiters completely disengage on overload thus preventing damage and down time to the equipment. 

When applied on red ucer output shafts in rectangular settling tan k drive systems, the "SE" Torque Limiter protects the drive chain, drag chain and flight bars.

They can also be applied on screw conveyor drives or other sludge collection systems that have potential for jamming.
