The Grundfos 15SQ15-290-230V is a 3 inch stainless steel submersible well pump rated for 15 GPM, 1 1/2 HP, 230V single-phase power, and a 2-wire configuration. Its SQ motor design uses permanent-magnet technology with an integrated electronic unit for efficient operation and soft starting.
Floating impellers with tungsten carbide/ceramic bearings provide high wear resistance in sandy conditions. Built-in overvoltage, undervoltage, overload, overtemperature, and upthrust protection help protect the pump and motor, while the 2-wire design supports straightforward installation without a control box.
This 3 inch submersible well pump uses a 2-wire design and is intended for installation in a well system.
Confirm the pump matches the system requirements, including 230V single-phase power and the 3 inch pump size.
Install the pump in the well system according to the manufacturer literature and applicable local requirements.
Make the 2-wire electrical connection and complete the system piping as specified for the installation.
If the well has a high static water level, follow the manufacturer recommendation to restrict maximum flow within the pump's recommended operating range to help prevent upthrust damage.
