Iwaki MXM Series Magnetic Drive Chemical Process Pump

The Iwaki MXM Series is a magnetic-drive, sealless chemical process pump designed for a wide range of chemical process duties — bleach, sulphuric acid, and other aggressive transfer applications. A patented self-radiating bearing-lubrication circuit and strategically placed heat-dispersion holes give the MXM proven dry-run capability and steady performance under process-upset or poor-suction conditions.

A two-piece rear casing improves pressure handling and adds a second containment barrier, while the front casing combines an injection-molded liner of guaranteed uniform thickness with a ductile cast-iron cover — pairing chemical resistance with mechanical integrity. All MXM designs ship with ANSI 150# flanged connections and use Samarium Cobalt magnet capsules for balanced torque transmission and efficient hydraulic operation, scaling to 146 GPM.

Patented dry-run capability — self-radiating bearing lubrication circuit withstands process-upset conditions
Heat-dispersion design — strategically placed holes behind the impeller remove frictional bearing heat under dry-run or poor-suction conditions
Two-piece rear casing — improved pressure handling and a second containment barrier
Injection-molded liner with uniform thickness, ductile cast-iron cover — chemical resistance + mechanical integrity
ANSI 150# flanged connections standard on every model
Dual-end-supported precision-ground shafts — balanced rotating assembly
Samarium Cobalt magnet capsules — lightweight, balanced inner magnet for efficient torque transmission
Rare earth magnets fully encapsulated in fluororesin moldings
Close-coupled back pull-out design — inspect the pump while leaving the line pressurized
Capacity to 146 GPM
