The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. The discharge port of the dredge pump is located near the top of the dredge pump and is connected to a separate discharge line. The front part of the pump casing is sealed with a suction cover and connected directly to the suction pipe of the dredger. The impeller is mounted in the pump casing and connected to the drive motor via a gearbox and shaft. How does a dredge pump work? A dredge pump contains a pump casing and an impeller. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning. The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. Without a dredge pump, a stranded dredger would not be able to deliver mud. It is designed to handle suspended abrasive granular materials and solids of limited size. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.ĭredge Pump What is a dredging pump? A dredge pump is a horizontal centrifugal pump that is the heart of a dredger. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The use of underwater pumps can effectively improve the above situation.

The number of dredging pumps is also increasing.Įspecially when the dredging depth reaches 20m or more, the above situation will be more obvious. With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher.
