Feature:
The structure of 200WN-500WN type dredging pump is single-casing, single-stage, single-suction, cantilever and horizontal. According to the connection with the gear box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.
The structure of 600WN-1000WN type dredging pump is double-casing, single-stage, single suction, cantilever and horizontal. It has self-carrying bracket. Lubrication is forced thin oil lubricating. The double-casing design can ensure the liner can work till it is worn out, and if the liner crack, water can not enter into the pump.
Application:
The dredging pump is widely used in dredging, digging mud and filling harbor in rive and sea all over the country such as the Yangtze Rive Basin, the Yellow Rive Basin, the Pearl River Delta, the Huai River Basin, Liaohe River Basin, harbors and wharfs.
