Centrifugal Pumps

The unique design of the Doda centrifugal pump housing and patented chopper blades makes the Doda pump a true leader in the field of pumping highly fibrous sludge and slurry. The high-speed open design impeller combined with the two static and one rotating chopper blade handles the most challenging solids.


Solids dewatering focuses on liquid reduction while providing safe handling and disposal of residuals. Slurries contain free liquid and bound liquid. Sedimentation, stationary and moving screens can only remove some of the free liquid, none of the bonded liquid and are only effective with extremely diluted wastes. Doda screw and roller separators accomplish solids separation by squeezing out all of the free liquid plus some of the bound liquid.
