ZN 26inch marine dredging pump

1,Production Overview:    ZN dredging pump is a new type of gravel pump researched & manufactured by our company,aiming at rivers and seas out of repair.ZN pump is a single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistan, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc.. It throughout meets requirements of the dredge to dredging pumps.       2,Main Features:    a) Advanced hydraulic model, CAD 3D design, high efficiency and obvious energy-savingb) Large dredging depth, high density of dredging mud, good NPSH and strong suction lift abilityc) Strong through-put. The pump can presistently discharge gravel, high plastic soil lump,etc.d) The pump can be directly matched with either motor or diesel enginee) Wide application. It can be used in various kinds of soil quality. 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 diameters and vane types to suit kinds of working condition.f) Little hydraulic loss, high efficiency and low oil-consumptiong) Little volume, light weighth) Steady operating, little vibration, low noisei) Simple & reliable constrution, easily disassembly & assembly,convenient maintaincej) Reliable sealing without leakagek) Long operating life of partsl) Long operating life of parts

3,Main Usages    ZN dredge pumps are widely used to dredge and dam in the rivers, ports and wharf over our country, such as Changjiang River, Huanghe River, Liao River, and Zhujiang Delta. Besides, sold to Europe, Middle East and Southeast Asia. CCS(China Classification Society) has inspected each set.
