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 (PAT). A special metal shaft is used on the MDW to withstand high radial forces and allow con- tinuous extended operation even under harsh service conditions.

The back pullout system allows easy maintenance and inspection without removing pipework. Integrated com- ponents and a sealed rear casing support structure enable motor re- moval safely without chemical leakage.
