“ Dewatering Pump are centrifugal pumps installed in a building that is situated below the groundwater level, to reduce the water level and then maintain it at this level. One example is in underground mining in which water penetrating into the adits is pumped up to the surface.

A dewatering pump is a centrifugal pump that is used wherever you need to remove water. You can use the pump at construction sites, in tunnels and mines and also in buildings where you need to remove unwanted water.

The type of dewatering pump used depends on what media you are going to pump. If you need to remove water with abrasives, then you use a drainage pump with a strainer that prevents bigger stones to enter the pump.

One of the most common dewatering methods is using dewatering bags. They are made of durable geotextile fabric which can filter water by removing sediments. Usually, dewatering bags are used on construction sites, dredging operations or areas with high water table near the shoreline. The dewatering bag should be sized relying on the type of sediment and the pump flow rate.” For more info, check out Tftpumps.com.
