The famous SP submersible pump celebrates its 50th anniversary Introduction Reports News Latest news Career be think innovate 06/22/2017 The art of combining efficiency, performance and reliability in an all stainless steel unit. The famous Grundfos SP pump is still a benchmark for submersible pumps around the world. This year we are celebrating its 50th anniversary, and although improvements and new options have been added, the original design remains the same. Hidden underground, the iconic SP submersible pump supplies hundreds of millions of people around the world every day. It has been on the market for half a century and its continuous technological development has ensured its evolution into the digital age. New developments in regulation, monitoring and adaptation make the SP pump a modern classic. “The SP pump remains a flagship product in our catalog, which definitely proves the innovation of the original design. The combination of design and material is always considered optimal, and through research and development we have managed to maintain our leading position in terms of energy efficiency and opportunities for improvement ”, says Søren Skjalm-Rasmussen, Director of Water Development at Grundfos. In total, four million SP pumps have been produced since Grundfos founder Poul Due Jensen introduced his first version in March 1967. It was the world's first fully stainless steel submersible pump, which quickly became famous for its reliability and performance. The SP has even won a prestigious design award for its balance between technology, functionality and form. A real component of future solutions In addition to the supply of drinking water, the SP pump is also a favored product for irrigation, where new digital solutions allow farmers to remotely control and monitor their installation. The stainless steel design provides very high strength to the SP pump. It can therefore also be used in mining operations, where environmental conditions demand rock-solid reliability. Nowadays, preserving water resources is just as important as energy efficiency. « Nous devons nous assurer que nous utilisons les eaux souterraines disponibles aussi judicieusement que possible. Le potentiel de la numérisation des installations d'irrigation est considérable et comme la pompe SP peut jouer un rôle évident au sein de ces solutions, elle peut largement contribuer à la résolution des défis liés à l’eau auxquels le monde est confronté », explique Søren Skjalm-Rasmussen. Jalon de la technologie de pointe Depuis 1967, la pompe immergée SP a énormément évolué. En 1982, l'introduction de l'arbre cannelé dans les pompes pour forages de particuliers a considérablement réduit le temps de production et la consommation de matériaux, et en 1992, les moteurs équipés de convertisseurs de fréquence intégrés ont été lancés. Lorsque la dernière génération de pompes SP (dénommées SP7/9/11/14) a été mise sur le marché en 2014, le rendement hydraulique a atteint un niveau exceptionnel, supérieur même aux exigences des normes européennes applicables aux constructeurs de pompes à eaux. De nombreuses options sont également disponibles. Grâce au Grundfos Solar Inverter (RSI), il est aujourd’hui possible de connecter la pompe SP à des panneaux solaires et d'utiliser ainsi une énergie durable, notamment dans les zones où l’accès au réseau électrique est difficile. It is estimated that around 1.3 million SP pumps are currently installed worldwide. The many improvements made to the SP pump make it a classic and state-of-the-art product, which has now proven its reliability for 50 years and which will undoubtedly remain one of the foundations of the Grundfos pump range for years to come. come.
