Grundfos® SQ/SQE Submersible Well Pumps

3-Inch SQ Submersibles

Grundfos 3” SQ pumps combine state-of-the-art design with rugged, quality construction. Designed to go into the same applications as standard 4” pumps, SQ’s light weight and small size make for fast, easy installation, especially in less-than ideal wells. With a host of advanced features, Grundfos’ 3” SQ pumps set a new stardard for what a submersible pump should be.

By combining advanced electronics with permanent-magnet motors, we are now able to control and communicate with pumps in ways never before possible. Some features that come out of this combination are, Soft-Start and integrated Dry-Run Protection. The SQ and SQE motors are based on a permanent-magnet rotor which produces high efficency output within a wide load range. Other benefits include reduced heat production and start-up torques comparable to 3-phase motors, in a simple-to-install 2-wire format Constant water pressure means you get the water pressure when you need it. As water consumption increases, pump performance automatically adjusts water pressure to meet the demand. The user-friendly control unit indicates how the pump is performing and warns of any faults. With a SmartFlo System, water pressure is maintained even if a family is showering, washing the car, and watering the lawn at the same time. All of your water supply needs are answered with a Grundfos SmartFlo SQE Constant Pressure System.
