Diesel Engine Gravel Sand Pump is designed specifically for the continuous pumping of extremely aggressive slurries, with a wide particle size distribution. It is can be used for handling large particles at consistently high efficiencies results in low cost of ownership.Tobee only uses the best materials for our pumps' components (casing, impeller, wear plates etc.). Tobee Gravel Sand Pump is single-stage single-casing horizontal dredging pump driven by diesel engine through a gearbox, The materials of gravel pump wear parts are made from high chrome alloy with hardness is no less than 60HRC, adopting grease lubrication for bearings to ensure stable running on the strong frame, It is widely used in the river platform, barges, marine ship or dredger for pumping sands, gravels, slurries, muds, sludges, stones or other big particle solids etc.
