700WNQ Underwater Dredging Pump
• Product Introduction
700WNQ dredging pump is 700mm size horizental centrifugal slurry pump.The
structure of the pump is single stage, single suction, and centerline
suction.These series submersible slurry dredging pumps adopt single pump casing structure,in order to reduce the pump weight, easy to
lift and move.The pump is installed on a special underwater frame on the side of the ship, which can be directly connected with the submerged motor,also can be connected with the ship's motor or electormotor through the long shaft.According to the connecting way of gear box can provide two kinds of typical structures, one is connected with own bearing bracket, the other is combined with reduction gear box. The
submerge slurry pump can meet the requirement of
working in single pump and two pumps in series.The pump can realize the variable-speed performance
at multi working condition points with the fine self-priming, wear resistance,
smooth operation, low noise and convenience for
overhaul and hoisting. It is equipped with the self-supply
seal water system with sand filter and lubricating system and has a long
service life and durability.
700WNQ is suitable for dredging
and filling operations of cutter-suction
dredger and trailing suction dredger. It is also used for river sand mining and
mining vessels.

1.The structure is simple and reliable.
The sand suction dredge pump adopts single pump casing structure,in order to reduce the pump weight, easy to lift and move.According to the connecting way of gear box can provide two kinds of typical structures, one is connected with own bearing bracket, the other is combined with reduction gear box. The lubrication of pump with bearing bracket is grease lubrication or thin oil lubrication.
2. Easy to assemble and disassemble and easy to maintain. The front dismantling structure is adopted, and special disassembly tools are equipped to facilitate disassembly and assembly.
3.The performance of dredging is excellent. The flow and head curve of the pump are steep, the suction ability is strong, the ability of passing the pump is good, the change of the distance is more applicable, and the depth of digging and the higher transportation concentration can be reached.
4.Good wear resistance and long life of flow wear parts. The impeller, volute liner, throat bushing and rear plate liner (wearable liner) are made of strong wear resistant alloy cast iron whose hardness is not less than 58HRC.It has not only impact on resistance but also high anti-abrasion performance.
5.Using advanced hydraulic model, the pump has low hydraulic loss, high efficiency and low energy consumption. The service life of each part is full considered in the process of product design. The same replacement cycle reduce the maintenance and replacement costs.
6.The shaft seal is reliable and no leakage.
The pump adopts mechanical seals or packing seals or combination of mechanical and packing seals.
