KIT SUBMERS. SOLAR PUMP (Grundfos SQF5A-7) + solar module

The following kit is a versatile Submersible Solar Pump kit that includes a Grundfos submersible pump (AQFlex 5A-7) with the controller and electrical equipment (KWATZFR0221), the borehole fittings (KWATZFR0222) and the solar module with the solar panels and structure (KWATZFR0223). It is designed to give maximum flexibility according to the expected yield available, daily water demand, solar energy (irradiation) and context (with the additional capabilities to make it hybrid and to work with surface water).

The present item includes all the three module components. But the individual components (or modules) of the kit can be purchased individually.

Technical specifications for the pump and the panels can be found in the specific modules description as well as in this item description.

Grundfos SQF 5A-7 – is a 4” diameter pump. It is fitted with an MSF 3 permanent magnet motor with an inbuilt electronic unit that converts incoming DC power to AC power. The pump is flexible as regards of power supply, so you can directly branch DC or AC power. The motor also features a built-in dry-run sensor electrode that automatically shuts the motor down if the water level drops below the sensor. The pump is fitted to a non-return valve on its outlet to prevent water from flowing back into the pump when switched off.

A simple IO 101 control unit allows for switching on/off, monitoring pump status as well as connection of a back-up AC single phase power supply. This pump is suitable for clean water, chemically non aggressive liquids without solids and fibres. So, if a surface water application is forecast, a proper strainer should be fitted to the pump, as showed in the documents annexed (contact your technical referent). The life time of the pump might decrease given the wear down due to sediments.

There is the option (recommended) to add the CU200 controler device to facilitate the automatization of the pump, if a floter is added. The floter is included in pump and electrical components module.

The system includes also 4 solar modules of 325 W each, and the structure to build the panels.

This kit should be used in different context:

1) As a first emergency context for groundwater or surface water supply. When used in surface water bodies, please contact the technical referent for adapting a strainer so the solids / vegetation is filtered before pumping.

2) Depending on the solar radiation and the characteristics of the borehole, the volume this pump will provide will change. Please, check the table below to have a guidance on the number of pumps and the flow rate you might expect from this system.

3) Remember that when used in a borehole, it would be great to know the safe yield of the borehole.
