Hydra-Tech’s S6CSL submersible 6” hydraulically driven sand slurry pump includes a built-in agitator designed to stir up heavy solids. This robust and powerful material mover has hardened wear components and is intended for use in applications where settled solids must be put into suspension and pumped away with the discharge water. The primary applications include de-silting, dredging and moving driller’s mud; other uses include filling sand bags to prevent beach erosion, tank and digester cleaning or pumping sediment from caissons. The small size allows the pump to fit through a 22 inch opening.  The S6CSL requires hydraulic inputs of up to 27 gpm @ 3000 psi and when combined with our HT50 to HT75 open and sound attenuated power units, the S6CSL is capable of output flows to 1200gpm. And, it will pump up against head pressure up to 130 feet.
