Grundfos SQ Pump: The 3 inch submersible well pump with advanced electonic protection!

The 3 inch SQ pump is the basic model of the 3" pump line. Grundfos SQ pumps are lightweight and their unique features offer protection from problems like low voltage, lightening, and dry-run (low water). Grundfos SQ pumps are available in flow ranges from 5 to 30 gallons per minute and depths to 600 feet.

Because they are lightweight, Grundfos SQ well pumps are easy to install. All SQ pumps come with an advanced two wire electronic motor and offer years of reliabe service. Perfect for home-water supply or a small business, the permanent magnet motor provides lower energy usage as compared to standard 4 inch motors. SQ motors are available in 240 volts in various horsepower options or 115 volt only in one-half horsepower, both in single phase.  Grundfos SQ pumps operate a single speed much like conventional pumps.  The difference is the SQ pump motor provides the benefits of electronic control that cannot be achieved with a conventional motor..
