SWECO SW ECO 414 & 518 C ENTRIFUGES H IGH S PEED, H IGH V OLUME L IQUID /S OLID S EPARATION T he Sweco® 414 and 518 Centrifuges are the premier high-speed, decanting centrifuges for fluids cleaning and solids removal and product recovery applications. Ruggedly built for industrial service, they are especially effective in environmentally sensitive areas. They deliver high recovery rates and efficient solids separation to significantly reduce disposal costs or reclaim valuable material from process streams. The Sweco 414 and 518 Centrifuges are precision-balanced for smooth operation over long periods at high RPM speeds, generating extremely high G-forces. The decanting centrifuge line is one of the focal points for the industrial treatment services now available through Sweco. The primary industries where industrial treatment services participate include (but are not limited to) Energy (Power Plants), Pulp & Paper, Agriculture, Refineries, Municipalities, Chemical, Food & Beverage, Waste Oil and Mining. ® Skid Mounted Low Profile Design Minimizes Space Requirements We Put Technology In Motion™ www.sweco.com Sweco Headquarters, P.O.

Long Service Life The heart of a Sweco Centrifuge is its high-speed, precision-balanced rotating stainless steel bowl. Inside the bowl, a double lead spiral screw conveyor rotates in the same direction as the bowl but at a slightly slower RPM. Feed slurry enters through a hollow axle at the narrow end and is distributed to the bowl. Centrifugal force as high as 712 G's at 1,900 RPM (or 2,149 G's at 3,300 RPM) holds the slurry against the bowl wall in a "pool". Trapped particles settle and spread against the bowl wall where they are scraped and conveyed to the solids under-flow discharge ports...
