Allweiler ALLMAG CNB-M
The Allweiler ALLMAG CNB-M is a volute casing centrifugal pump with a magnetic drive (MagDrive) in a compact block design, developed for applications up to PN 25. Designed for leak free operation, the pump combines proven centrifugal pump hydraulics with sealless magnetic drive technology, making it particularly fitting for handling fully desalinated water and aggressive fluids.
The magnetic coupling eliminates the need for a mechanical shaft seal, reducing maintenance requirements and preventing product leakage, which is especially important in chemical processing and marine applications.
