Applications

  • Domestic ground water intake — Groundwater is essential for water supply. Providing a reliable, fresh supply of water for all homeowners is equally essential, particularly for those whose water source is a private groundwater well.
  • Domestic water pressure boosting — Low or varying water pressure in the home? A water pressure pump solves the very common problems of low-pressure showers and trickling taps that reduce comfort in one- or two-family homes.
  • Ground water intake — You require a cost-effective, reliable and energy-optimised submersible pumping solution for borehole installations. Our pumps and pump systems are optimised for the highest performance and reliability for groundwater installations.
  • Solar water solutions — Grundfos supplies solar-powered water pumps and complete solar water solutions that deliver unmatched flexibility for reliable water supply with no ongoing energy costs.
