Powerful and Reliable

Grundfos SQ pumps are 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 conventional motors lack. The pump will automatically stop anytime the water supply discontinues preventing damage to the pump. This is also an energy efficient process that prevents unnecessary and damaging power. When the low voltage or low water supply is resolved, the pump will automatically restart and resume pumping. Every time the pump starts, it begins pumping softly to ensure there are no well disturbances or water hammering. These features are perfect for situations where constant supervision is not possible.

All Grundfos SQ pumps use permanent magnets in their brushless motors, providing reliability and service for years to come! All SQ pumps come with a standard two year warranty. Call us to order your Grundfos SQ pump today!
