SQFlex 6SQF-3 Submersible Helical Rotor Pump 5.8 GPM 820 ft
The Grundfos SQFlex 6SQF-3 is a submersible helical rotor pump designed for high-head water pumping applications. It supports power input from 30–300V DC or 90–240V AC and can operate from solar, wind, battery, inverter, generator, or utility power sources. With a 2.9-inch diameter body, it fits wells 3 inches or larger. Built-in protection helps guard against dry running, overload, and overheating.
KEY FEATURES
- Helical rotor design is intended for high-head water pumping applications.
- Provides flow rates up to 5.8 gallons per minute.
- Supports pumping lifts up to 820 feet.
- Accepts 30–300V DC or 90–240V AC power input.
- Can operate with solar, wind, battery, inverter, generator, or utility power sources.
- Requires a solar array with an operating voltage above 30V for direct solar operation.
- Can operate from a solar array starting at 129W under specified operating conditions.
- Built-in protection helps prevent damage from dry running, overload, and overheating.
- 2.9-inch diameter pump body fits wells measuring 3 inches or larger.
- Compatible with optional CU200, IO50, IO100, IO101, and float switch contr
Optional Controls:
- The CU200 interface box communicates with the pump and monitors operating conditions. Built-in diagnostics indicate faults and low water shut off, display operating status, power consumption and float switch input.
- The Float Switch interfaces with the CU200 control to turn off the pump when a tank is full.
- The IO50 and IO100 are simple control boxes with cable terminations and a manual on/off switch. It is a great interface between a solar array and the pump to allow you to turn off the high voltage array when working on the pump.
- The IO101 is an interface for using AC backup on a solar pump. An automatic transfer switch disconnects the solar array when AC power from a generator, utility connection or inverter is present. When AC power stops, it automatically reconnects the array to let the sun continue pumping.
You can use several controls if you need more features than one control can provide.
