MCH series
MAGNETICALLY DRIVEN CENTRIFUGAL CHEMICAL PUMPS
Horizontal, normal suction, single-stage, magnetic driven chemical standard pumps in close-coupled or process design made of stainless steel or wetted pump parts made of non-metallic materials also according to ATEX 2014/34/EU.
Magnetically driven centrifugal pumps of the "MCH" series are made of rugged solid block material in polypropylene or PVDF. They work completely without mechanical shaft seal and are therefore leak-free. The power is transmitted by a forced-locked connection without contact through strong permanent magnets on the hydraulic part. The sliding bearing material used is exclusively PTFEC. The pump shaft is made of high-purity oxide ceramics (99.7%) as standard. These manufacturing features ensure utmost service life and optimum corrosion resistance. Magnetically coupled centrifugal pumps of the "MCH" series meet the highest demands in terms of safety and reliability when pumping the most aggressive, toxic and environmentally hazardous liquids.
