Description
Grundfos 5SQE05-90 1/2HP 200–240V 60Hz Deep Well Submersible Pump – is a compact, high-efficiency deep well pump designed to provide Constant Pressure for residential, agricultural, and light commercial groundwater applications. Part of the proven Grundfos SQE series, this model combines durable stainless-steel construction with advanced motor control to deliver reliable water supply from narrow boreholes and deep wells.
The 5SQE05-90 is equipped with a 1/2 horsepower submersible motor optimized for 200–240 VAC, 60 Hz operation. Its high-speed motor and multi-stage hydraulic design allow it to deliver consistent flow and pressure from significant depths while maintaining efficient energy use. The pump is suitable for domestic water supply, irrigation systems, livestock watering, and pressure boosting applications where dependable long-term performance is required.
Designed for installation in 3-inch and larger well casings, the pump features corrosion-resistant stainless-steel components and an IP68-rated submersible enclosure for continuous underwater operation. Integrated motor protection functions, including thermal overload protection and soft-start behavior, help reduce electrical stress and extend service life. The compact form factor and standardized discharge connection make integration into new or existing well systems straightforward.
NOTE: Must be used with either of the following controllers: CU301 or CU302 Constant Pressure Kit with Transducer to be able to provide constant pressure
