SUBMERSIBLE - DEM

The DEM series offers all the advantages of a recessed impeller pump in a submersible package. The high chrome
recessed impeller allows for an unobstructed passage through the pump casing (also made of high chrome
construction) which allows solids, up to the full diameter of the discharge, to pass through without the danger of
clogging. Long fiberous materials are handled without difficulty. As one of the most efficient recessed impeller pumps
on the market today, the DEM boasts operational efficiencies once only achievable by its ‘closed’ and ‘semi-open’
impeller cousins. The DEM’s axial spiral casing design ensures that flowing solids are discharged quickly, reducing
internal recirculation that can be detrimental to the hydraulic efficiencies and pump wear life. Due to the natural flow
of the fluid through the pump casing and the fact that the flow is virtually isolated from the impeller, (only 15% of
pumped liquid is in contact with the impeller) fragile solids can be passed through the pump with very little damage.
This pump is ideally suited for low shear applications.

The best news is that because the Toyo recessed impeller wet ends are standard across all our lines of recessed
impeller pumps, from cantilevers to line-shafts to submersibles, any critical parts stocking costs can be reduced
to an absolute minimum even if you are operating a number of different Toyo recessed impeller pump
configurations.
