The Grundfos 22SQ07-120-230V is a 3 inch stainless steel submersible well pump rated for 22 GPM, 3/4 HP, and 230V single-phase power. Its 2-wire design simplifies installation, and the SQ motor uses permanent-magnet technology with an integrated micro-frequency converter.
This pump is built for efficient operation with soft start, high motor efficiency, and hydraulic components designed for low energy consumption. Wear-resistant floating impellers with tungsten carbide/ceramic bearings help improve sand resistance, while integrated protection features help guard against overvoltage, undervoltage, overload, overtemperature, and upthrust during startup.
This 3 inch Grundfos SQ submersible well pump uses a 2-wire design and 230V single-phase power for straightforward setup.
Confirm the well is suitable for a 3 inch submersible pump.
Install the pump according to 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.
After startup, verify the pump is operating within its recommended range.
