6 Inch Centrifugal River Sand Dredging High Chrome Hard Alloy Anti-Wear Sand Dredge Pump
Introduction
1. Gravel Sand pump (dredge pump) is designed as single casing connected by means of clamp
bands and wide wet-passage.
2. The wearing parts are made of ultra chromium abrasion-resistance alloys, long service life
and very low failure rate.
3.The pumps are designed for continuously transferring strong corrosive big-solid -contained
slurry which the common slurry pump cannot transfer. They are widely used in dredging,
sand excavation; mining, explosive-sludge in metal melting, etc..
4. G series gravel pump is often installed on cutter suction dredger or barge.
5. Gravel pump outlet direction can be in any position of 360· This type of pump possesses

1. Single stage, single case, metal liner, horizontal anti-abrasion centrifugal pump.
2. Advanced hydraulic model, CAD-aided design, high efficiency and remarkable energy-saving effect.
3. Strong flow capacity. The pump can pump gravel, high plastic clay lumps and so on.
4. Strong matching capacity. The diesel engine and the motor are both available.
Application:
G Series sand gravel pumps are designed to handle abrasive and large particles for gravel and dredging operations.
G sand gravel pumps are designed for the continuous handling of the most difficult higher abrasive slurries,
containing solids too large to be pumped by a standard slurry pump.Such as :
Suction Hopper Dredging / Cutter suction Dredger / Constructional Material / Sand gravel processing
