Dredging Gravel Pump

Sand and gravel dredging pump activities are essential in various contexts, including beach reclamation, river dredging, port and marina maintenance, or extraction of these materials.

Our dredging pump can be used as marine dredging pump for dredging purposes. Marine dredging is the process of excavating and removing material from the bottom of an ocean, river, pond etc. Dredging is mainly used for marine construction projects, mining, sediment removal, environmental remediation, canal deepening, harbor maintenance, and many more. Marine dredging requires different types of dredgers, and the dredging pump is the core equipment of the dredger, which is called the "heart" of the dredger in the industry.

Marine dredging pump features:

1). The number of vanes of the impeller is 3-5 to ensure sufficient passing capacity;

2). It must have good cavitation performance to ensure the dredging effect of the pump under the condition of large excavation depth;

3). Outlet diameter of dredging pumps of φ 600 below, bearing lubrication generally using grease lubrication structure, for φ 600 and above using thin oil lubrication or thin oil lubrication station for forced lubrication;

4). Shaft seal type: packing seal, liquidyne seal, mechanical seal with packing compound seal;

5). Small hydraulic loss, high efficiency and low energy consumption;

6). Good wear resistance, long service life of flow parts.
