During construction, it is impossible to predict the weather forecast for a long period. The excavated foundation pit may be flooded with rainwater and construction work may be suspended for an extended period. The site has here sufficiently powerful submersible pumps capable of operating in the harsh conditions of contaminated liquids. Pump water out of the pit quickly and efficiently, eliminating the need for builders to wait for it to naturally evaporate.
Efficiency of submersible pumps
The equipment is directly lowered into a pit with stagnant water. As soon as it is put into operation, the pump continues to function until it removes unnecessary liquid from the artificial reservoir. The main advantages of a reliable system include:
- the impeller is protected from the negative effects of abrasive;
- chop up the debris so that it does not cause the pump to break down;
- high head of liquid lifted from the depth;
- effective work for many hours;
- the sealed construction is not afraid of being completely immersed in water.
The submersible pump is compact in size. It does not need additional equipment and special conditions for operation. It only needs a stable source of electrical energy to work.
Features of the choice of pumping equipment
The range of pumps is quite large. The selection should be based on the technical and operational capabilities of the equipment. When choosing, you should be guided by the following recommendations:
1. Pumping unit weight.
2. Performance per hour.
3. Availability of automatic and manual configuration.
4. The ability to create sufficient pressure, transporting water through pipes.
The last parameter is especially important, since in many cases water is pumped into the drainage system of the city or to a neighboring open area. In this case, the length of the pipes can be up to several tens, and even hundreds of meters. The high wear resistance of the casing and impeller will allow it to be used on many projects for pumping contaminated liquids from pits.
