Heavy duty centrifugal large gravel dredge pump of anti-abrasive material A05,A49,Cr26,Cr27
WN dredge pump is a new type of sludge pump researched & manufactured by our company,aiming at rivers and seas out of repair.WN dredge 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.
Application
WN 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.
Construction
200WN to 500WN dredge pumps are of single casing, single stage cantilevered horizontal centrifugal pumps. Two types of coupling with gear box: frame and pump box.
600WN to 1000WN 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.
Easy Uninstallation & Convenient Maintenance
WN 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 Performance
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.
Material
Material of wet parts is high wear resistant high chrome alloy.
Considering the maintenance, wear resistant parts are nearly of the same wear life to reduce maintenance & interchange costs.
