Delin Machinery specializes in the production of slurry pumps, dredge pumps, desulfurization pumps in China. Description DG Series dredge pump on the basis of surveys at the pump dredge used in the country and abroad. We spent a lot of statistical analysis to drag pumps and slurry pumps. The adoption of various design techniques and promotion of computer assistant design software, is a brand new series of DG dredge pump is used for deep sea or marine dredging, including sand and gravel extraction, transporting or suspensions. These series DG dredge pumps have excellent performance, excellent structure design, easy maintenance and long service life, etc.
Features Dredge Pump
1. DG series dredge pumps from one stage, single suction horizontal structure. According discharge pressure, they are divided into two categories: one pump and the pump casing double hull.
2. The double hull design increases the reliability of protection. If the spiral liner becomes close to being worn out, or split, there will be no leakage of the water pump inside the house. Single dredge pump housing is lightweight and small volume. All of our HD Series dredging pumps can pan. The depth of immersion can meet different requirements. Bearings to use well-known domestic and foreign brands. This series dredge pump has long uninterrupted work time. 3. DV series dredge pump uses the structure of the front and easy to dismantle the stall, disassemble and repair. Various components have special disassembling tools.
4. Our pump dredge accepts standard thread for connecting the impeller and shaft, and is equipped with a removal of the piston ring for easy impeller mounting.
