SQFlex
Application
Designed for continuous as well as intermittent opera-
tion, 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
- surface water pumping
• Floating pump installations for pumping of water
from ponds and lakes.
The 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 is equipped with the
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 control unit
• IO 100 and IO 101 switch boxes
• IO 102 breaker box
• energy supply:
- solar panels
- wind turbine
- generator
- batteries.
Pump
The SQF pump range comprises two pump technolo-
gies:
• Helical rotor pump (3") for high heads and moderate
flows.
• Centrifugal pump (4") for lower heads and high
flows based on the Grundfos SP A pump.
The performance curves below illustrate pump perfor-
mance for the two pump technologies:
Motor
The SQFlex motor range comprises only one motor
size, the MSF 3 with max. power input (P1) of 900 W.
MSF 3 is a 3" motor.
The speed range for the motor is 500-3000 rpm
depending on the power input and the load.
The motor has been developed especially for the
SQFlex system.
The SQFlex motor has three internal limitations,
• max. power consumption (P
1
) of 900 W
• max. current of 7 A and
• max. speed of 3000 rpm.
The pump delivers its maximum performance when one
of the above limitations is reached.
The motor is available in stainless steel EN/DIN 1.4301.
The motor is designed according to the permanent-
magnet principle with built-in electronic unit.
Voltage supply
The motor can be supplied with either AC or DC
voltage.
• 30 - 300 VDC, PE
• 1 x 90 - 240 V –10%/+6%, 50/60 Hz, PE.
