Allweiler ALLMAG CNH-M Centrifugal Pump

The Allweiler ALLMAG CNH-M is a volute casing centrifugal pump with magnetic drive (MagDrive) in a baseplate-mounted design, developed for applications up to PN 25. Combining proven centrifugal pump hydraulics with sealless magnetic coupling technology, the CNH-M provides reliable and leak free handling of fully desalinated water and aggressive fluids.

By eliminating the need for a mechanical shaft seal, the magnetic drive minimizes maintenance requirements and virtually eliminates product leakage, making the pump particularly fitting for chemical processing and marine applications where safety and environmental protection are critical.
