ASK A QUESTION

 

The SQFlex 1-8 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 SQFlex 1-8 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
