DSC Marlin Dredges Deeper


The Marlin Class underwater pump mining dredge manufactured by DSC Dredge LLC is designed to meet the needs of deep mining and aggregate deposits by providing a more efficient tool for material excavation. Every Marlin Class dredge is specifically designed to handle a particular deposit – from sand and gravel to industrial minerals – to ensure maximum efficiency.

Deep digging capability is made possible by the use of an underwater pump system with a high torque cutter drive assembly to complement the rigorous demands of the deep mining industry. Digging depths range from 35 ft. (10 m) to more than 200 ft. (61 m), an achievement unmatched in the dredging industry. Discharge sizes range from 8 in. (203 mm) to more than 24 in. (610 mm) to allow for a wide range of production and flow conditions to match specific mining operations.

DSC Marlin Class dredges are available in either a diesel- or electric-powered model to meet the customer’s specific needs. Drive systems include a Caterpillar ACERT diesel engine with inline direct marine style transmission for dredge pump reduction, or TEFC electric motor, variable frequency AC dredge pump motor drive and double helical gear reducer for dredge pump reduction.
