EnglishCentrifugal Pump M7
Normal suction, magnetically driven, leak-free centrifugal chemical pump, all wetted pump parts made of non-metallic materials in modular concept, according to CE regulations.
MARCH magnetically driven centrifugal chemical pumps operate entirely without mechanical shaft sealing. The power is transmitted to the hydraulic part by a force-locking connection using powerful permanent magnets, without physical contact. MARCH magnetically driven centrifugal chemical pumps meet maximum requirements in terms of quality, economy and reliability when pumping aggressive, toxic and environmentally hazardous liquids.
Features
- Leak-free
- Magnetic driven
- Closed coupled
- Normal suction
