Features of MDW series
High Discharge Capacity and High Head
The heavy-duty MDW is capable of a maximum discharge capacity of 5,000 L/min. discharge head of 98 m, enabling applications in previously unexplored areas with a wide range of liquid specific gravities.
Highly Chemically Resistant
Fluoroplastic and fine ceramic wetted parts offer high resistance to virtually every industrial chemical, irrespective of concentration.
Use of the high strength ductile cast iron external armour is mandatory for heavy duty chemical process applications. High casing pressure resistance is achieved with a unique rear casing design preventing stress concentration and incorporating a triple-layer structure. A special metal shaft is used on the MDW to withstand high radial forces and allow continuous extended operation even under harsh service conditions.
The MDW is dimensionally compliant with the international standard (ISO2858, 3661) and is interchangeable with conventional sealed centrifugal pumps.
The back pullout system allows easy maintenance and inspection without removing pipework. Integrated components and a sealed rear casing support structure enable motor removal safely without chemical leakage.
A New Lineup Has Flange-Connection Type
Flange-connection type has been adopted while maintaining high durability for chemical process applications. Contributes to reducing installation space and improving maintainability.
Application example
- Chemical transfer between supply tanks and through chemical process equipment.
- Chemical recirculation for filtration and heat exchange applications.
- Scrubber liquid recirculation.
- Replacements for conventional sealed pumps.
