A dewatering pump is one of the many types of speciality pumps offered by Crompton. It is a pump which is used to remove water from places.  A centrifugal pump uses rotational kinetic energy to move liquids from one place to another. It can be used to extract water which is situated below ground level.

Depending on the requirements, there are several ways in which dewatering pumps can be used. If you need to pump out groundwater using a submersible pump, then a deep hole may be dug which allows groundwater to seep into the hole. A round liner with slots along the edges should be inserted. Once this is done, a dewatering submersible pump can be placed at the bottom of the hole, which will pump the water out.

Another way to use it is by placing the dewatering pump above ground. Then a series of small tubes may be inserted into the ground. The dewatering pump can then draw water out through these tubes.
