Delin Machinery is specializing in manufacturing slurry pumps, desulfurization pumps and dredge pumps in China.

The designation of DG series dredge pump is based on surveys on dredge pump used domestically and abroad. We

have conducted a lot of statistic analysis on dredge pumps or sludge pumps. Adopting different advance designing

methods and computer assistant designing software, this is a brand new DG series dredge pump, applied for deep

sea or offshore dredging, including extraction of sand and gravel, or transporting slurries. These DG series dredge

pumps feature excellent performance, outstanding structure design, ease of maintenance, and long service life, etc.

Features of Dredge Pump

1. DG series dredge pumps are of single stage, single suction, horizontal structure. According to discharging pressure, they are classified into two categories: single casing pump and double casing pump.

2. Double casing design enhances the safety reliability. If volute liner is getting close to being worn out, or split, there will be no water leakage inside pump house. Single casing dredge pump is of light weight and small volume. All of our DG series dredge pumps can be sump. The submerging depth can meet different requirements. Bearings use famous domestic or foreign brands. This series of dredge pump has long trouble free working time.

3. DG series dredge pump uses front dismantling structure, and is easy to stall, disassemble and repair. Different components have special dismantling tools.

4. Our dredge pump adopts standard screw thread for the connection of impeller and shaft, and equipped with removing of piston ring for the ease of assembling the impeller.
