Grundfos 4″ SP submersible pump range

Grundfos has launched an extended range of high-efficiency, medium-sized SP submersible groundwater pumps. The 4″ SP pump range has been expanded from two to three sizes (with one more to follow) and is built in stainless steel with three different material grades available, covering liquids from drinking water to seawater.

The European Ecodesign Directive Ecodesign requirements for rotodynamic water pumps are established using the Minimum Efficiency Index (MEI). The extended range of groundwater pumps surpasses the required MEI value of 0.40.

The range meets drinking water approvals wherever it is sold. The pump is CE labelled and is said to have increased wear resistance.

Built to deliver optimum efficiency during periods of high demand, the pumps are claimed to provide low long-term costs and high operating reliability regardless of the application. Made entirely of corrosion-resistant stainless steel, they are suitable for a wide variety of applications, such as groundwater supply to waterworks, irrigation, pressure boosting and in industry.

The range offers high efficiency, high resistance to abrasives and easy maintenance. In addition to dedicated motor protection devices, a complete monitoring and control system is available for constant optimisation of the pumping system.
