Dewatering pumps are designed specifically to evacuate and move water from certain areas. These pumps are built with a lightweight construction that allows for portability and insertion/installation in tight spaces. Typical installation areas include pits, basins, storage tanks, reservoirs and drainage ditches. Of course, as dewatering pumps are submerged in water, it is also important for the casing, shaft and seal materials to be corrosion and abrasion resistant.
Here is a diagram of some typical installations:
Goulds Water Technology dewatering pumps are some of the finest on the market, combining versatility, precision engineering and consistent performance. Pump Products currently carries three series of dewatering pumps from Goulds: the 1SC series, the 1DW series and the 2DW series.

| Goulds 1SC Series |
Goulds 1SC series pumps are drainage booster pumps for high pressure dewatering applications. They are mainly used for pumping water out of reservoirs and storage tanks and can often be found in houses, farms, mobile home parks and motels. Each pump contains multiple stages (3, 4 or 5) for increased pressure applications. 1SC pumps can handle up ⅛” suspended solids and can be submerged in water up to 65 ft. Single- and three-phase models available.
