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.
through GSM by connecting to CIU Flex
High-efficiency pump with a permanent magnet motor
The SQF 1-8 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.
