But because of the capacity and discharge requests, only one pump couldn’t finish the project. And according to the other requests, such as flow capacity, particle size, we recommend the large capacity dredge pump 300 GN – 50 pump set for him. The dredging depth is 15m, the discharge distance is 2000 m. There was 5 dredger sets in his working site. If not, when the pump is working, the discharge distance won’t meet the requirements.įor example, there was one of our customer from Lebanon, he wanted to dredge sand for the river. The booster pump requests that the pump head should be enough, especially in a project with two booster pumps or more. To be as the booster pump, the most importable thing is the position of the pump, or we can call it head. The inlet connects with the discharge pipe from the dredge pump, booster pump or other equipments, and then, discharges the sand, mud and other mixture to the next booster pump set or the stock pile. Second, as the booster pump, the large capacity dredge pump will be setup on the land or others platform. If the pump position is higher than the water level, it will need a water pump to fill the sand pump with water from the river or the other water source. When the water in the pump case is high than the half of the pump impeller, the pump can start to work smoothly. Because if the water level is higher, the water can backflow to the pump. For these types, the position of the pump is better to be lower than the water level. discharge distance can get to 700 – 1000 meters.įirst, as the main suction pump, the large capacity dredge pump will be setup on the dredger hull or a working platform, connected with the suction hose directly to dredge. This dredge pump is usually used as the booster to do the long discharge. And in China, the GN series is the most popular. The total discharge distance will be about 300 – 500m according to the different working condition and sand source. In Africa, PNS series of this large capacity dredge pump is widely used on the sand dredger for sand suction and river dredging. There is the same flow capacity of these two series, the difference is the pump head. OCEAN brand sand dredge pump have two series, one is PNS series and another one is GN series. This sand pump is always used as main dredge pump on the dredger or as the booster pump for long distance discharge on the land. Large capacity dredge pump is a kind of heavy duty sand suction pump for river cleaning, sand dredging and mining.
