Dewatering Applications

Your dewatering needs are our top priority. Our electrical submersible pumps support all your dewatering application needs for drainage, slurry, and sludge. Visit our dewatering applications section to learn more about various types of dewatering needs.

These applications call for pumps designed specifically for handling corrosive and abrasive materials and their solid contents.

The non-clogging Sonora S540 Submersible Sludge Pumps are tough on handling thick, soft, wet mud or other similarly viscous mixtures of liquids and solids. Our high-chrome impellers provide higher wear resistance to move solids up to 2-inches at 370 GPM.

Applications: water containing mud, sludge or light slurry, tank clean-out, trench & pond cleaning, and mining


Get turnkey solutions that include dredge hoses, slurry flow meters, power units, and more. Choose from multiple sizes of slurry hoses for the transferring of materials, wireless flow meters for measuring the flow rate in gallons per minute of liquid, and power units for operation. Parts are always in stock and available for immediate shipping to anywhere in the US and the world.
