Product Overview

Grundfos 11 SQF-2 Submersible Pump

The SQFlex system is a reliable water supply system based on renewable energy sources, such as solar and wind energy. The SQFlex system incorporates an SQF submersible pump. Very flexible as to its energy supply and performance, the SQFlex system can be combined and adapted to any need according to the conditions on the installation site.

  Type: Helical Rotor.
  Head: 395 ft.
  Max Flow: 13 gal/min.


  30-300 VDC and 90-240 VAC, can be used to run the pump (either DC or AC voltage supply),
  50hz or 60hz (both),
  SQFlex 3SQF through 11SQF pumps will fit into a 3" well,
  Can deliver from 82 gpm at 6 feet of head to 4 gpm at 800 feet with a 1.6 kilowatt solar array or less,
  Helical rotor pumps (models 3, 6 and 11) for high head applications,
  Centrifugal pumps (models 16, 25, 40, and 60) for low head applications assure a pump that is efficient for any use.

The SQF pump range comprises two pump technologies:-

  The helical rotor pump (3") for high heads and small flows,
  The centrifugal pump (4") for low heads and large flows.

The SQF pump complete comprises:-

  6 ft (1.8 m) cable with water level electrode and socket,
  Cable guard,

The positive displacement helical pump ends are:-

  3” in diameter and available in five models ranging,
  3 to 11 gpm (0.68 to 2.50 m3/h),

As an option we offer the product together with float switch or pressure switch reverse action. A few words about both components:

The water level float switch interfaces with the CU200 control smart box to turn off the pump when a tank is full. Since the CU200 control circuit uses only 15 milliamps, the water level switch can be located in a tank that is as far away as 1,640 feet from the pump, using a minimum 18ga two conductor wire. In order to use the level switch you have to buy CU200 smart box and the level switch as a combo. Two year warranty. The level switch or CU200 smart box can be separately purchase as an alternative.

A pressure switch reverse action will control the pump’s on/off operation via the pressure in the storage tank. The pressure switch is in  normally-open configuration, where the contacts within the switch are in the open position when the pressure is below the maximum set-point. When the pressure in the system rises to the maximum desired pressure, the contacts will close, signaling the pump to shut off. The pressure switch will open and close in a reverse order of the contacts normal open normal close position. The pressure switch is mounted after the pressure tank and before the water outlet. The pressure switch works together with CU200 smart box. They must be bought together. A full system will have both of the pressure switch and float switch connected to a CU200 smart box.

Before you buy be aware of the return policy conditions and read the manufacturer warranty.
