Heavy duty dredging pumps are designed for continuously handing the most difficult higher abrasive slurry which contain too big solids. The Heavy duty dredging pumps 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 heavy duty dredging pumps are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.

1. The Heavy duty dredging pumps is horizontal, single pumps casing structure centrifugal pump.

2. Use special clamp clamping pump body and pump cover, the pump outlet can be adjusted in the any direction of 360 degrees, easy to install and use.

3. The bearing components with cylindrical structure, easy to adjust the gap between the impeller and the pump body to keep long working life .

4. Bearing with grease lubrication.

5.The Heavy duty dredging pumps has three kinds of shaft seal including packing seal, vice impeller seal, mechanical seal.

6. Wide flow channel , good cavitation performance, high efficiency, abrasion resistance.

7.Transmission methods are: V-shaped V-belt driven, flexible coupling driven, gearbox transmission, hydraulic coupling driven, thyristor speed control speed and so on.

8.Over-flow components Material: nickel-containing high-chromium wear-resistant alloy.

9.Using variety speed and variants, making the pump running in the best conditions .

10. Long working life and high operating efficiency can meet a variety of bad working conditions .

Heavy duty dredging pumps is suitable for dredging dredger, sand suction dredger, sand pumping, mining and metal smelting slag transportation. Because of its good passing performance, it is currently widely used in inland river dredging.

 Heavy duty dredging pumps (also known as Heavy duty dredging pumps, sand and gravel pump) is mainly used for long distance transportation of strong abrasive materials that are too large for general sand pumps to convey.

Mr. Li from Zhejiang engaged infrastructure projects in Angola, and the demand for sand and stone was relatively large. There is a local river with a width of 100 meters and a water depth of about 5m, the sand in the river is good building material because the sand resource is rich and sand quality is good. Many people pumping sand from the river. Mr. Li also wanted to pump sand for his projects, the extra can be sold.

Mr. Li contacted OCEAN Pump, after detailed communication, we recommended to make a 8 inch sand dredger hull equipped with Heavy duty dredging pumps ZS200. The dredger hull should be made according to container dimension for transporting. The Heavy duty dredging pumps inlet is 8 inch, outlet is 6 inch. The Heavy duty dredging pumps has wide flow channel so it is not easy to be blocked, and this kind of Heavy duty dredging pumps is high wear resistant because the whole pump casing is thickened. All the advantages of the Heavy duty dredging pumps can cut the maintenance cost for abroad using. Mr. Li has worked abroad for many years, he can weld and make the dredger hull according to his actual requirements in the local site, this saves transportation cost, and needn’t to be restricted by the transportation conditions. After the scheme was determined, our factory provided all the equipment except the dredger hull, such as sand suction pump, pipeline, lifting and pumping device equipped with the hull. OCEAN Pump started to produce after receive the deposit.

Ocean Pump engineers guided the foreign workers to install the Heavy duty dredging pumps into the dredger hull by on-site video and pictures, ensured the workers operated the sand pump machine successfully. At the same time, OCEAN Pump prepared one more set of Heavy duty dredging pumps assembly and wearing parts, several more sets connecting elbows and butt flanges for replacement. The customer highly appreciated the high quality Heavy duty dredging pumps and our professional service.
