Grundfos submersible wastewater and groundwater pumps are designed as sealed units combining a pump and integrated motor that can operate below the surface of the pumped fluid. These pumps represent advanced hydraulic design and offer high efficiency, high resistance to sand and other abrasives, motor burnout protection and easy maintenance. Made entirely of corrosion-resistant stainless steel, Grundfos submersible pumps are ideal for applications including groundwater supply, irrigation, groundwater lowering and pressure boosting.
