200AWN to 500AWN Dredging Pumps are of single casing, single stage cantilevered horizontal centrifugal pumps. Two types of coupling with gear box: frame and pump box.


600AWN to 1000AWN dredge pumps are of double casings, single stage cantilevered centrifugal pumps. These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.


AWN dredge pump is of front uninstallation construction to make uninstall easily and convenient maintenance. And special tools are equipped for uninstalling the parts. Standard four-head trapezoid thread connection between impeller and shaft can transfer powerful torsion and be convenient to uninstall. Impeller uninstall ring at shaft sleeve side also make the impeller uninstallation much easier.


Good NPSH can not only guarantee suction but also make deep dredge and high allowable suction density. 

Minimum NPSH: 4m. 

With wide impeller passage, pump can continuously pump gravel or high plastic clay without clogging. 

Max allow particle size: 350mm. 

Performance curves descend obviously to make pumps adopt pipeline distance changes. 

By changing the impeller diameter or impeller rotating speed, it can easily change the discharge with the same flow rate.
