The S4SHR-LP 4-inch hydraulic submersible shredder pumps from Hydra-Tech Pump continuously rip and shear solids with a 360-degree shredding action. The carbide-tipped impeller and hardened macerator suction plate work together to produce a violent shredding action that keeps the discharge open. This 4-inch pump is great for municipal, industrial, agricultural and institutional waste applications. Its narrow 21.5-inch size allows it to fit through most manholes. Depending on the application, there is a version for portable or fixed installations. A guide rail assembly is available for stationary applications. Combined with HT15 to HT35 power units, it is capable of flows up to 810 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.
