Technical data M3 (2.22 MB)

Normal suction, magnetically driven, leak-free centrifugal chemical pump made of non-metallic materials in modular concept, according to CE regulations.

MARCH magnetically driven centrifugal chemical pumps operate entirely without mechanical shaft sealing. Power is transmitted to the hydraulic part by strong permanent magnets in a contactless and force-locking manner. MARCH magnetically driven centrifugal chemical pumps meet maximum requirements in terms of quality, economy and reliability when pumping aggressive, toxic and environmentally hazardous liquids.


  • Leak-free
  • Magnetic driven
  • Closed coupled
  • Normal suction
