The Iwaki MDW magnetic drive pump increases the capacity range of their market-leading process pumps with the introduction of the new MDW series. The MDW series is dimensionally compliant with ISO2858 & 3661 to enable easy replacement of conventional sealed pumps. The unique sealed back pullout design allows complete withdrawal of the bearing housing, while keeping the pump casing fully intact and pipework in place.

Materials
Virgin and carbonfibre reinforced ETFE, or PFA fluoropolymer wetted parts with SiC shaft sleeves, bearings and thrust rings provide maximum resistance to virtually all corrosive industrial chemicals.

Connections
All models have ANSI flanged connections as standard, with ISO flanges optional.

Capacities
Three basic models operating at either 2900 or 1450rpm are available with a range of impellers sizes..Magnetic couplings for motors from 11 to 75kW cover flows to 300m3/hr and heads to 106m, making MDW amongst the largest non-metallic pumps available in the world.

Motors
All models are fitted as standard with IP55 outdoor rated foot mounted industrial motors.

Iwaki MDW Magnetic Drive Pump — Overview

The Iwaki MDW magnetic drive pump is a high-capacity industrial sealless centrifugal pump specifically engineered as a drop-in replacement for conventional mechanically sealed process pumps. Its ISO 2858 and ISO 3661 dimensional compliance means the MDW can be installed directly into existing pipework without modification, dramatically reducing changeover time and cost.

Key Features

• ISO 2858 & 3661 Compliant — The MDW magnetic drive pump meets international dimensional standards, enabling direct replacement of sealed end-suction process pumps with zero pipework changes.
• Sealed Back Pull-Out Design — The unique bearing housing can be fully withdrawn while the pump casing and pipework remain intact, minimising maintenance downtime.
• CFRETFE, Virgin ETFE & PFA Wetted Parts — Maximum chemical resistance to virtually all corrosive industrial chemicals, including strong acids, alkalis, and solvents.
• SiC Shaft Sleeves, Bearings & Thrust Rings — Silicon carbide throughout wetted rotating components for maximum wear and chemical resistance.
• ANSI & ISO Flanged Connections — Standard ANSI flanges with optional ISO configuration for flexible installation.

Technical Specifications

Three basic MDW models cover a wide capacity range suitable for large industrial processes. The back pull-out feature and standardised dimensions make the MDW the preferred choice for plant engineers retrofitting sealless technology into existing pump systems.

Applications

The Iwaki MDW magnetic drive pump is ideal for chemical manufacturing, mining acid transfer, pharmaceutical production, water treatment, and any industrial process currently using ISO-standard sealed pumps where leakage elimination is required.
