The Grundfos 10SQ07-200-230V is a 3 inch stainless steel submersible well pump rated for 10 GPM, 3/4 HP, and 230V single-phase power. Its 2-wire design supports straightforward installation, and no control box is required.
The SQ motor uses permanent-magnet technology with an integrated micro-frequency converter for efficient operation across a wide load range. Soft start helps reduce starting current, while floating impellers and tungsten carbide/ceramic bearings provide wear resistance in sandy conditions. Built-in protection features include overvoltage, undervoltage, overload, overtemperature, and upthrust protection.
This Grundfos SQ submersible well pump is designed for 230V single-phase operation and uses a simple 2-wire configuration.
Confirm the well is suitable for a 3 inch submersible pump.
Install the pump following the manufacturer literature for this model.
Connect the pump to the specified 230V single-phase power supply.
If the well has a high static water level, use a Dole flow restriction valve to keep flow within the recommended operating range and help prevent upthrust damage.
Start the pump and verify operation stays within the recommended range.
