Description

Solar Pumping System

SQFlex

Renewable-energy-based water supply systems 50/60 Hz



Applications

Being designed for continuous as well as intermittent operation, the SQFlex system is especially suitable for water supply applications in remote locations, such as:

• villages, schools, hospitals, single-family houses, etc.

• farms

– watering of cattle

– irrigation of fields and greenhouses

• game parks and game farms

– watering applications

• conservation areas

– pumping of surface water

• floating pump installations for pumping of water from ponds and lakes.



SQFlex system

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.

The system components are:

• SQF submersible pump

• CU 200 SQFlex control unit

• CIU 273 SQFlex GRM control unit

• IO 50 SQFlex switch box

• IO 101 SQFlex switch box

• IO 102 SQFlex breaker box

• charge controller

• energy supply system:

– solar panels

– wind turbine

– generator

– batteries.



Pump

The SQF pump range comprises two pump technologies:

• helical rotor pump (3") for high heads and small flow rates

• centrifugal pump (4") for low heads and large flow rates.

The performance curves below illustrate the pump performance of the two pump models. All pump types are available in two material variants:

• SQF is the standard version made of stainless steel DIN W.-Nr. 1.4301

• SQF-N is made of stainless steel DIN W.-Nr. 1.4401.
