1. Simple and reliable structure

The 200WN-500WN type dredger pump adopts a single pump casing, single-stage single-suction cantilever horizontal structure as a whole. According to the connection method with the gearbox, two types can be provided

Typical structure, namely the built-in bracket type and the pump box integrated type. The self-contained bracket type lubrication method is grease lubrication or thin oil lubrication.

The 600WN-1000WN type dredger pump adopts a double-shell pump, single-stage single-suction cantilever horizontal structure as a whole, with its own bracket. The lubrication method is forced thin oil lubrication.

The safety and reliability design of the double-shell pump ensures that the sheath can be used until it is nearly worn through, and when the sheath breaks, water will not enter the pump chamber.

2. Easy to disassemble and assemble, and convenient for maintenance

The WN type dredger pump adopts a front-disassembly structure, which is simple to disassemble and assemble and easy to maintain. At the same time, in light of the structural characteristics of each component, dedicated disassembly and assembly workers are provided

It is easy to disassemble and assemble.

3. Good wear resistance, long service life of flow-through components, and excellent cavitation performance

The impeller, sheath and front and rear guard plates (wear-resistant bushings) of the WN type sludge pump's flow-through parts are made of strong anti-wear alloy cast iron with a hardness of no less than 58HRC, and have

The new material recently developed by the company not only has strong impact resistance but also a high degree of abrasion resistance. Its hardness can reach 70HRC. WN type

The dredger pump has excellent cavitation performance, which can ensure strong suction capacity of the dredger pump, and at the same time achieve greater dredging and higher suction concentration.

4. The shaft seal is reliable with no leakage

The shaft seal of the 200WN-500WN type dredger pump adopts mechanical seal, packing seal or a composite seal of mechanical seal and packing.

The shaft seal of the 600WN-1000WN type dredger pump adopts a spiral sleeve L-shaped rubber sealing device. This sealing device consists of three L-shaped sealing rings and one belt

The shaft sleeve is composed of special threads.

The WN series of dredger pumps were independently developed by our company in response to the current situation where rivers, lakes and seas have been in disrepair for a long time and the dredging and filling work is extremely urgent

A new type of mud pump developed. This series of sludge pumps adopt single-stage single-suction cantilever horizontal centrifugal pumps, featuring light weight and strong wear resistance.

It features excellent dredging performance and significant comprehensive economic benefits in use, which can fully meet the requirements of dredgers for mud pumps.

The WN series of mud pumps developed by our company using various advanced computer-aided design software have a long service life and high efficiency

High, reliable shaft seals, and remarkable comprehensive economic benefits. Excellent excavation performance can transport high-density mud. The mud pump itself is superior

The cavitation performance and super strong suction capacity can continuously pump gravel or high-plastic block clay without clogging.
