Grundfos 10SQ05-110-115V is a 3 inch stainless steel submersible well pump rated for 10 GPM, 1/2 HP, 115V single-phase power, and a simple 2-wire design. SQ series motor technology uses a permanent-magnet motor with integrated electronics for efficient operation, soft starting, and built-in protection features.
This pump is designed for wear resistance with floating impellers and tungsten carbide/ceramic bearings for sand handling. Integrated protection helps guard against overvoltage, undervoltage, overload, overtemperature, and upthrust during critical start-up conditions.
This 3 inch SQ series submersible well pump uses a simple 2-wire design for single-phase 115V installation.
Confirm the pump matches the application requirements for 10 GPM, 1/2 HP, 115V power, and 3 inch diameter fit.
Install the pump as a submersible well pump following the manufacturer literature and applicable local codes.
Make the 2-wire electrical connection for single-phase power as specified for this model.
If the well has a high static water level, follow the manufacturer guidance on restricting flow to keep operation within the recommended range and help prevent upthrust.
Start the pump and verify normal operation within the recommended operating range.
