MARCH magnetic-drive chemical centrifugal pumps work entirely without a mechanical shaft seal. Power is transmitted without contact and with a positive fit to the hydraulic part by strong permanent magnets. MARCH magnetic-drive chemical centrifugal pumps meet the highest demands for quality, economy and reliability when pumping aggressive, toxic and environmentally hazardous liquids.
Centrifugal pump M2
Normal-suction, magnetic-drive, leak-free chemical centrifugal pump with wetted pump parts made of non-metallic materials in close-coupled design, to CE directives.
