MD series The centrifugal pump is driven by a pair of magnets which are incorporated in the impeller and motor shaft. The sealless pump structure eliminates shaft seals such as conventional mechanical seals because the pump chamber is shielded by the casings and the impeller is operated by the magnets. The combined coupling torque of the drive magnet and impeller magnet gives sufficient driving power against the motor torque. Driven magnet Operating Principle Drive magnet High corrosion-resistance Easy maintenance GFRPP(Grass fiber reinforced polypropylene) wet ends of the MD series handle...

MD series Large capacity type High-head type Construction Motor Drive magnet The 6- or 8-pole high power ferrite magnet drives the impeller through the rear casing. O ring Rear casing GFRPP single-piece rear casing has the bearing mounted at the bottom to support the spindle. Spindle Front casing Hose or threaded connections can be selected according to application. Also union joints can be installed on threaded connection models. Impeller Note: MD-6, 6Z and 10 models do not have the bearing. The ferrite magnet is encapsulated into the impeller. For rotating spindle models, an alumina...
