Application: Overload Clutches for Wastewater Applications The drive on wastewater speed (usually less than 1 RPM) and consequently produce massive amounts of unnecessary torque. This torque can destroy drive components, increase maintenance costs and create unplanned downtime if a jam were to occur. torque without breaking drive components or creating an undesirable repair situation. WOR clutches are stainless and nickel plated to withstand these tough wastewater processing applications. Model WOR overload clutches are designed for use on clarifers, scrapers, bar screens, cross collectors or settling tanks. • Stainless steel and nickel plated for superior corrosion resistance • Available in automatic or manual reset styles • Torque range from 850 to 30,000 in. lbs. • Jaw style adapter is available or an H78 plastic sprocket can be supplied mounted to the clutch • Adjustable torque setting with a limit switch plate notifies operator if a jam occurs

Altra Industrial Motion Rectangular or circular clarifiers are frequently used as a primary step in wastewater processing and will remove 20% to 60% of the solids. These clarifiers are essentially large tanks of dirty water that typically have a flocculant added to help the heavy solids settle to the bottom of the tank or float to the top. At the bottom of rectangular clarifiers you will normally have a scraper system that is chain driven and removes the sludge for further processing. The circular clarifiers will similarly have a rake or scraper arrangement at the bottom to remove the sludge,...
