SQFlex is the perfect sustainable, reliable and cost-efficient alternative to irregular, cost-intensive water supply solutions in remote locations. It provides individual solutions to water problems where conventional water supply systems fail or simply cannot reach. 

The complete SQFlex pump range consists of 10 different pump sizes: 4 helical rotor pumps for medium to high heads and low to medium flows, and 6 centrifugal pumps for shallow heads and high flows. It is available in AISI 316 stainless steel for slightly aggressive water. The pump is fitted with a high efficiency motor for DC or AC voltage. This makes pump sizing and selection extremely easy.


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
  • Watering applications
  • Conservation areas
  • Floating pump installations for pumping of water from ponds and lakes.
