E Q U I P M E N T G A L L E RY Conveyor Covers • Victaulic connections allow for flexibility and ease of maintenance. • "Duck Bills" can be attached to the cyclone apex with siphon control to accommodate variable feed solids conditions. • The sump is constructed with heavily reinforced ¼-in. walls and wide flange beam vertical columns. • A sloped bottom plate promotes even solids flow to the pump inlet and an automatically adjusted make-up water valve protects the pump. • A sturdy hand railed stairway and platform on both sides and back of the screen allow for safe access. • Several pump configurations are available mounted on a steel frame base pad. www.deistermachine.com www.e-mj.com Superior Industries' new belt covers are rigid and strong. Each cover is built standard with 22-gauge steel, which is folded at the edges to nearly double the strength at this crucial point of stress. The corrugated design also benefits installation and maintenance efforts, removing a requirement for additional supports, socovers are self-supporting. Also, installation is not dependent on the location of an idler frame. Instead, owners can attach the covers with self-tapping screws at any point along the length of a conveyor's structure. They are available in standard sizes up to 60 in. width (1,524mm) in 42-in. (1,066-mm) lengths and various coverage styles. www.superior-ind.com Knuckle Buster Channellock has introduced a 30-in. (762mm) 830 adjustable wrench. The crescent wrench complements the existing adjustable wrench line and is a full 6 in. longer than what was previously offered. The 830 provides added power and leverage, as well as a jaw capacity up to 3 in. These improvements coupled with the fact that the wrench is forged from chrome vanadium steel for durability and performance makes it capable of handling the biggest and most demanding jobs. www.channellock.com Diesel Exhaust Fluid Prestone now offers the Command line of Diesel Exhaust Fluid (DEF). Command DEF is a liquid reducing agent that has been developed for use in all diesel engines equipped with a Selective Catalytic Reduction (SCR) system. SCR is an emissions-control technology that injects a precise amount of DEF into a diesel-powered vehicle's exhaust stream, which in turn converts any nitrogen oxide present into harmless nitrogen and water vapor that is subsequently released safely into the atmosphere. Some estimate that DEF de- JUNE 2013 • E&MJ 163
