ZN series high efficiency new designed dredger pumps are particularly suitable for dredging, filling and other operations in rivers and lakes.
It fully meets the requirements of the dredger for mud pumps. They are composed of a pump head, reducer gear box, high elastic coupling, and marine transmission monitoring system.
ZN600 inlet diameter is 28 inches and the outlet is 24 inches.The inlet is bigger, which can increase the flow capacity and working efficiency and reduces cavitation.
