The Company Delin Machinery (Delin machine) specializes in the manufacture of mud pump, désulfurisations pump, dredging pump in China. The appointment of DG pump series is based on the use made of dredging pumps on the national and international market. We did a lot of statistical analysis on dredging pumps and the sludge pump by adopting different methods of design, IT support or software; This pump is the newest pump series DG, used for deep sea dredging, extraction of sand and gravel as well as transportation of the sludge. The DG series of dredge pump has excellent performance, a remarkable structure, easy maintenance and a long life Characteristics 1.La series dredge pump DG has a single stage (stage), a simple, horizontal suction structure According to the discharge pressure of the pump is classified into two categories: single pump housing and the pump housing double 2.La double casing design improves the safety and reliability of the pump, if the coating becomes obsolete or if there is crack, there will be no leakage of water inside the pump. The single housing to dredge pump has a light weight and small volume. All our DG series dredge pumps are submersible. The immersion depth can meet different requirements; bearing uses foreign or domestic brand. This dredge pump series have a long working time. 3. Our DG series dredge pump uses before disassembling structure, making it easy to maintain and repair; There are various special tools in place to ease disassembly
4. The standard thread standard is adopted for connecting the wheel and the shaft, with the piston rings to ease the mounting of the wheel
