Wide Channel Nonblckage Sand Gravel Dredging Pump with Powerful Suction

Product DescriptionWide Channel Nonblckage Sand Gravel Dredging Pump with Powerful SuctionThe Sand Gravel Dredging Pump is designed for continuously handling the most difficult higher abrasive slurries which contain too big solids. The gravel sand pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging, and so on. The advantages of the pump are a heavy flow, easy installation, and operation, good performance of NPSH, and abrasion resistance.The Sand Gravel Dredging Pump is designed for continuously handling the most difficult higher abrasive slurries which contain too big solids. The big particle gravel sand pump is cast as a single pump casing structure with a smooth over-current channel. The overflow part is made of hard nickel and high chromium wear-resistant alloy. The outlet direction of the gravel pump can be adjusted according to the requested direction. The gravel sand pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging, and so on. The advantages of the pump are a heavy flow, easy installation, and operation, good performance of NPSH, and abrasion resistance. Product ParametersModelFlow(m³/h)Head(m)Speed(r/min)ID/OD(mm)Max.

It is mainly used in a working environment with high flow requirements and is suitable for pumping pebbles and large particles. Granular mud, domestic garbage, medium-coarse sand, and other media. Large-particle Sand Gravel Dredging pumps began to be used in industrial and mining enterprises and later developed into engineering projects such as river dredging, sand pumping, and embankment consolidation. The unique three-blade impeller of the Sand Gravel Dredging Pump has a wide flow path, a thickened pump casing impeller design, and the selection of high chromium alloy materials for the flow parts, which greatly enhances the service life and ensures long-term stable and efficient operation in sand pumping operations, The application range is very wide. Sand Gravel Dredging Pumps are not suitable for all working conditions. The disadvantages of this type of pump are first that there are fewer blades and the outer diameter of the impeller is relatively small. Therefore, the shaft power is relatively lower than that of marine sand pumps or high-lift slurry pumps. Some, the result is that under the same power ratio, the output will be lower than the other two pump types, so customers need to consider this factor in the selection process.In June 2020, a user in Cameroon, an African country, contacted the foreign trade manager of OCEAN PUMP and put forward the following construction requirements:For river sand pumping, the high chrome gravel pump made in Guangdong was previously used. The effect is good but the wear is faster. I hope to use the high chrome gravel pump of wear-resistant a
