G/ WS(G) /WN Wear resistant corrosion resistant river sand dredging pump
G pump is designed specifically with advantages of little volume & weight, good wear-resistant & dredging performance, perfectly suited for the dredge on the whole construction.
| Design | Single-stage single-suction cantilever horizontal centrifugalsludge pumpaiming at dredging and damming of the river and seas.Persistently discharge gravel, high plastic soil lump and so on. |
| Operation | Steady operating, little vibration, low noise, simple & reliable construction, easily disassembly & assembly, convenient maintaining, obvious economic efficiency and energy-saving. |
| Material | Strongly wear-resistant casting alloy iron, whose hardness is not less than 58HRC |
| Installation | The pump can be directly matched with either motor or diesel engine, reliable sealing without leakage, long operation life of parts & MTBF |
| Application | Wide application, large dredging depth, high density of dredging mud, good NPSH, stronger suction lift ability, Little hydraulic loss, high efficiency and low oil-consumption |
| Structure |
200WS-500WS type pumps are single-casing, which uses the mechanical sealing or stuffing sealing or mechanical stuffing compound sealing. 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. 600WSG-1000WSG type pumps are double-casing, which adopts spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and one special thread shaft sleeve. It has self-carrying bracket. Lubrication is forced thin oil lubricating. 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. |
