Dredger Pumps

As one of professional dredge pump manufacturers, SGB provide sand dredge pumps with high quality. A dredge pump is a horizontal centrifugal pump and is the heartbeat of a dredge. The dredge pump is designed to take in sediment, debris, and other harmful materials from the surface floor into a suction pipe, carrying the material to a discharge site through a pipeline.

Pump Features

- Advanced hydraulic model, CAD-aided design, high efficiency and remarkable energy-saving effect.

- Strong flow capacity. The pump can pump gravel, high plastic clay lumps and so on. Dredge pump is generally equipped with three vanes or five vanes, used to handle different particle size respectively.

- Strong matching capacity. The diesel engine and the motor are both available.

- Small size, light weight.The whole machine and every component of the dredge pump all adopt optimization design and strength analysis, this can greatly reduce  the pump weight by minimizing unnecessary auxiliary structure and process structure on the premise of satisfying the performance and  application requirements.

- Stable running. small vibration and low noise. The dredge pump uses high-level static balance , optimum speed and auxiliary support structure of pump head to ensure  stable operation during the production process of impeller. The pump has good cavitation performance to ensure strong suction capacity. greater dredged depth and higher concentration of inhalation medium.

- Simple structure, easy to dismantle and maintain.As a whole, the Sand dredge pump is single-stage, single-suction horizontal and cantilever structure. It can also be disassembled from the front  part. So the pump is easy to dismantle and maintain, the parts of the pump are good in exchangeability.

- The parts have long service life.The parts are made of high chromium wear-resistant alloy whose maximum hardness is more than 60HRC, and they have long service life.

- Reliable seal, no leakage.The O-rings are used on all static seal surfaces, such as between casing and front liner plate, casing and rear liner plate, rear liner plate and  stuffing box, ; the shaft seal uses mechanical seal with water or packing seal to ensure normal operation for a long time.

- The whole machine has high reliability and remarkable economic benefits.In the design process of the whole machine, every problem-prone part needs full consideration and optimization design to greatly raise  trouble-free working time. The pump has advantages of simple structure and easy to dismantle and maintain. This can reduce lahor  intensity and workload, and increase economic benefits. 

- The steep drop type of performance curve. The head and capacity curves of N series dredge pump drop steeply, so the pump has strong adaptability to changes of spoiling distance.
