Grundfos CRN MAGdrive Leak-free pumps for hazardous media Need to pump dangerous, aggressive, volatile or precious media? Then what you really want is a completely leak-free pump. Grundfos designed the CRN MAGdrive to be exactly that. Its pump shaft is rotated from the outside by the forces of magnetism, so the liquid cannot escape its closed circuit. Everything stays put – which is good news for your processes, your working environment, and the environment in general. Rated power up to 22 kW The advantages of the hermetically sealed magnetic drive are available on CRN pumps with a rated power up to 22 kW. No matter how powerful a motor you need, you get a pump which combines high speed and compactness – and the benefits of patented technologies you won’t find anywhere else. Naturally, the MAGdrive series has the superior reliability and performance you expect from a CR soluti

Being responsible is our foundation Thinking ahead makes it possible Innovation is the essence How it works A magnetic coupling uses the force of magnetism to transmit power from the drive to the shaft. As the illustration shows, the magnets are located inside completely separate parts – only the force of magnetism connects the two. When the drive moves the magnets marked “A”, it makes the magnets marked “B” turn as well, causing the shaft in the liquid to rotate and create the required pumping action. In contrast to traditional pumps, the shaft does not penetrate through the two parts. This...
