Sonora Submersible Sludge Pumps
The DAE Pumps Sonora Submersible Sludge Pumps are designed for an extensive range of applications. Their robust design provides the performance, reliability, and ease of use you need for transporting water and solids. The Sonora Submersible Pumps are capable of pumping solids up to 2-inches at 420 GPM with up to 9.2 HP. The Sonora Series offers a range of models in 3-inch and 4-inch sizes.
Sonora pumps are made to perform. The unique sealing system and modular design make them the most flexible pumps on the market. Easy to use and maintain, Sonora pumps provide the optimum maintenance solution and can be easily fitted at the job site. These heavy-duty submersible pumps offer a motor protection system with a built-in starter and optional automatic level control. The hardened high-chrome impellers and adjustable wear-resistant rubber diffuser feature ensure durability in the toughest environments.
At DAE Pumps, we have a complete range of high-quality submersible sludge pumps made for dewatering, moving mud, clay, sludge, light slurry, tank clean-outs, trench & pond cleaning, and mining applications. The user-friendly design and easy-to-use Sonora pumps are why they are the preferred choice of sludge pumps.

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 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. Sonora sludge pumps are available in 3-inch and 4-inch sizes and able to move up to 420 GPM.
Applications: water containing mud, sludge or light slurry, tank clean-out, trench & pond cleaning, and mining
