Submissive sludge pump 800/40 is designed to be installed directly on the arrow of the ground intake device of the dredger. During operation, during the operation of the dredger, along with the arrow of the primitive device, it is immersed in water. The possibility of operating the pump in a diven position gives a number of positive points:
- the process of starting the pump is facilitated, because The running part of the submersible sludge pump itself is filled with water;
- When the pump is operating in a immersed state, a bearing node is cooled several times more intensively;
- The most important and main positive effect is that when the pump is operating in a immersed state, a certain excess pressure appears in the absorption pipeline, depending on the depth of immersion. The presence of excess pressure in the absorption pipeline reduces the likelihood of a harmful cavitation phenomenon and, as a result of the premature wear of the details of the prototype part of the submersible sludge pump. Also, in the presence of excess pressure, hydraulic losses in the absorption pipeline are reduced, the conditions of absorption are improved, which allows the soil fence from the bottom of the quarry more efficiently, reduce energy consumption and ultimately receive an economic effect.
As a drive, an electric motor (electric submersible sludge pump) is used through a drive shaft. Recommended degree of protection of the electric motor IP55.
Details of the prototype part of the submersible sludge pump are completely interchangeable with the details of the flow of the GRU pump 800/40. The design of a bearing submersible sludge pump provides reliable operation for a long time in a immersed state.
