COMPETITIVE SOLAR WATER SUPPLY
from shallow wells with low daily flow requirements
The perfect solar-powered pump for replacement of a wind-powered or hand-pump water supply
FINALLY
The perfect match for small-scale solar water supply
The 5 SQF-8 is a solar submersible pump designed for water supply from shallow wells, with low daily flow requirements. Because of its small size, it is a perfect match as a replacement pump for a wind-powered or hand-pump water supply, and the pump also excels as part of a battery system. This makes it the most competitive solar water supply solution on the market for these small-scale applications.
The 5 SQF-8 is – like its larger siblings in the world-renowned SQFlex family – an intelligent pump with high-efficiency permanent magnet motor available with multistage centrifugal hydraulics and low starting voltage.
- Built-in Maximum Power Point Tracking (MPPT) software and motor protection
- Wide voltage range and flexibility for AC/DC power sources
- Dry running protection
- Easy to install and extremely reliable
- Tank filling system by connecting to CU200 and remote monitoring through GSM by connecting to CIU Flex
High-efficiency pump with a permanent magnet motor
The 5 SQF-8 pump comprises of a MSF motor and composite hydraulic centrifugal pump (3") for low heads and low flow rates. The permanent magnet motor speed range is 3000-10700 rpm.
The pump (5 SQF) and the motor (MSF 3) are made of stainless steel AISI 304 (DIN W.-Nr. 1.4301).
Build a complete SQFlex system
The SQFlex system ensures great reliability and efficiency for water supply based on renewable energy sources, such as solar and wind energy. In addition to the pump and renewable energy source, an SQFlex system incorporates all necessary controls, communication and ancillary units installed as one complete system.
The SQFlex system can be combined and adapted to any need, matching the conditions on the installation site. The choice of energy source and wide-ranging performance ensures extreme flexibility, and the SQFlex system can also be powered by generator and battery, if required.

Performance Curve for the 5 SQF-8
The performance curve illustrates the relationship between flow rate (Q) in m³/h and US GPM, and power input (P1) in Watts and HP. The graph displays multiple curves representing different head levels (15 ft, 35 ft, 50 ft, 65 ft, 100 ft, 130 ft).
The X-axis represents Power Input (P1) ranging from 0 to 400 W (0 to 0.40 hp). The Y-axis represents Flow Rate (Q) ranging from 0 to 10 m³/h (0 to 2.0 US GPM).
