Features
√ Advanced hydraulic model, CAD 3D design, high efficiency and obvious energy-saving . √ Large dredging depth, high density of dredging mud, good NPSH and strong suction lift ability. √ Strong through-put. The pump can persistently discharge gravel, high plastic soil lump,etc. √ The dredge pump can be directly matched with either motor or diesel engine. √ Wide application. It can be used in various kinds of soil quality. Generally, the dredge pump is matched with an impeller with 3 or 5 pieces of vane. √ Little hydraulic loss, high efficiency and low oil-consumption, Little volume, light weight, Steady operating, little vibration, low noise. √ Simple & reliable construction, easily disassembly & assembly, convenient maintenance, Reliable sealing without leakage, Long operating life of parts.
