MARCH magnetic-drive gear pumps of the MARCH MASTER GEAR series are externally toothed gear pumps in close-coupled design with magnetic coupling and work entirely without a mechanical shaft seal. Power is transmitted without contact to the hydraulic part by strong NdFeB permanent magnets. MARCH magnetic-drive gear pumps meet the highest demands for quality, economy and reliability when pumping a wide variety of media.
