The range has been expanded from two to three sizes and is built in stainless steel, with three different material grades available, covering liquids from drinking water to seawater.
"We have invested substantially in extending the SP range and in new production facilities in Denmark, showing our commitment to the market for medium-sized submersible groundwater pumps," says global product manager Jakob Overgaard.
As well as exceeding the demands of the new European Ecodesign Directive, the 4" SP range meets drinking water regulations worldwide.
Grundfos says it offers high efficiency, high resistance to sand and other abrasives, reliable motors and easy maintenance. A complete monitoring and control system is available.
"In addition to meeting the new Ecodesign Directive requirements, the potential for energy saving is substantial,” added Mr Overgaard.
