Iwaki MDM Series Magnetic Drive Chemical Process Pump

The Iwaki MDM Series is a magnetic-drive, sealless chemical process pump engineered for the most demanding aggressive-chemical handling — bleach, sulphuric acid, caustics, and high-purity transfer duties. A unique non-contact system design lets the pump withstand dry running where conventional fluororesin mag drives would fail, the operating temperature range expands to 300 °F, and solids handling rises to 10% — addressing real-world process conditions other mag drives can’t.

Two materials of construction and convenient close-coupled mounting configurations adapt the MDM to a wide spectrum of chemistries, while the modular back pull-out design lets operators inspect or service the pump while the line stays pressurized. Total head reaches 350 ft (107 m) at flows to 400 GPM (1,514 LPM).

Dry-running tolerant — carbon/ceramic non-contact design protects the pump if the suction line empties
Expanded temperature range — operates up to 300 °F
10% solids handling — runs in conditions that defeat conventional fluororesin mag drives
Two materials of construction — fit a wide range of aggressive and high-purity chemistries
Compact close-coupled design — reduces installation footprint and maintenance time
Modular construction — individually replaceable parts lower long-term cost of ownership
Back pull-out design — inspect or service the pump without depressurizing the line
High-strength rare earth magnets fully encapsulated in fluororesin moldings
Small, lightweight concentric magnet capsules — optimize hydraulic efficiency
Capacity to 400 GPM (1,514 LPM); head to 350 ft (107 m)
