11 sqf 2

SQFlex pumps can be directly powered by solar or wind or can be run on an inverter, 11 sqf 2, generator, battery, utility grid, or any combination of these sources. Its motor is designed to draw a maximum of 8.

The Grundfos SQFlex solar pumps can be directly powered by solar or wind power or can be run on an inverter, a generator, a battery or the utility grid, or any combination of these sources. They can operate on a series string of PV modules with a total peak power voltage over 30 volts, but the pumps efficiency will be much higher at voltages over VDC. SQFlex 3 and 6 pumps will fit into a 3" well. Seven pump models can deliver from 2 gpm at feet to 65 gpm at 20 feet of head with a 1 kilowatt solar array or less. Helical rotor pumps models 3, 6 and 11 for high head applications and centrifugal pumps for low head applications assure a pump that is efficient for any use.

Model 11 SQF-2 is designed for flow up to 12 gallons per minute and lifts of up to feet. Maximum power used is watts. It can be directly powered by solar or wind or can be run on an inverter, a generator, a battery bank or the utility grid, or any combination of these sources. Virtually any source of power, VDC and VAC can be used to run the pump, and with the name Grundfos on it, you know it is built to last and is maintenance-free. The 2. Helical rotor pump for the most efficient high head applications. Will not tolerate sandy water due to the tight internal tolerances of the helical rotor. The SQFlex has built-in protection from dry-running, overload and overheating. The SQFlex pump can run on a solar array starting at watts. The array must have an operating voltage over 30 volts. The array can be made with any combination of 3 or more 12 volt nominal modules in series. Higher voltages will optimize pump performance and minimize wire size needed. A 24 month from start-up, 30 month from date of manufacture warranty is standard. You can use several controls if you need more features than one control can provide.

The SQFlex has built-in protection from dry-running, overload and overheating. The connection to the pump would be done with an underwater splice kit. Microhydro Turbines.

Solar Water Pumping. 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 SQFlex pump can run on a solar array starting at watts. The array must have an operating voltage over 30 volts. Please Sign in or create an account. You can use several controls if you need more features than one control can provide. Product no A reverse action pressure switch is used in situations were a float valve i s required in most cases this is due to the feet max distance between the cu and the float switch. An automatic transfer switch disconnects the solar array when AC power from a generator, utility connection or inverter is present. The connection to the pump would be done with an underwater splice kit. Call Us! Add to Project.

Quick Find. Solar Water Pumping. Model Number. Pump Motor Specifications. Thanks so much. They can operate on a series string of PV modules with a total peak power voltage over 30 volts, but the pumps efficiency will be much higher at voltages over VDC. Advanced Search. Skip to the beginning of the images gallery. When AC power stops, it automatically reconnects the array to let the sun continue pumping. Seven pump models can deliver from 2 gpm at feet to 65 gpm at 20 feet of head with a 1 kilowatt solar array or less.
