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.

Goulds 1DW Series

The 1DW “Ditch Wizard” pumps are expressly built for handling dirty waters in dewatering applications. These pumps can be used in draining ditches and pits, industrial water drainage and general excavation in the building trades. To that end, each 1DW pump can handle up to ⅜” spherical solids. The pumps can be submerged in up to 23 ft. of water.''

Goulds 2DW Series


Like it’s cousin the 1DW series, the 2DW “Ditch Wizard” pumps are designed to move water from drainage ditches, as well as trenches, basements and manholes. 2DW pumps are constructed with durability and corrosion-resistance as the priority. Each pump features a polyurethane impeller and diffuser (with a rubber lining around the impeller), a bottom strainer made of EPDM impact-absorbing rubber and dual seals. The strainer can handle any size incoming solids.
 
In addition, the 2” NPSM threaded hose coupling discharge can be configured for either vertical or horizontal discharge depending on the piping. 2DW pumps come with single phase motors built with automatic full overload and temperature protection. Can be submerged up to 16.5 ft.
