The S3SHR 3-inch hydraulic-drive submersible shredder pump from Hydra-Tech Pumps continuously rips and shears solids with 360-degree shredding action. It uses an open-vane shredder impeller with tungsten carbide cutting tip. Compact size allows it to fit in tight spaces. A guide rail assembly is available for stationary applications. Combined with HT11 to HT20 power units, it handles flows up to 450 gpm. The safe and variable-speed hydraulic drive can be used where electric power is hazardous or impractical. 570-645-3779; www.hydra-tech.com.
