ZN250 type dredge pump is constructed by a pump head, reducer gear box, high elastic coupling, and marine transmission monitoring system. Grease lubrication or thin oil lubrication is optional.

It has the features of good wear-resistance, large dredging depth, high density of dredging mud, good NPSH, strong suction lift ability, easy maintenance and strong through-put.

And the pump can be directly matched with either motor or diesel engine.

Generally, the pump is matched with an impeller with 3 or 5 pieces of vane. At the same time, the impellers can be provided with various diameter and vane types to suit kinds of working condition.

The pump is applicated for heavy duty conditions such as mining, power sector, dredging river, and tailings as well as specialty applications, which are used for continuous pumping of high abrasive, high density sand and gravels.
