The AFI pump is a high-pressure chopper pump which can be mounted on a tractor or connect to direct power source. Vanadium and manganese alloy chopper blades chop the slurry prior to pumping, allowing for fuel efficient, block free operation. An oil cooling system keeps the gearbox cool even in heavy and prolonged conditions resulting in the most efficient, low maintenance agricultural pressure pump on the market.
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.
Doda manufactures a variety of propeller mixers for the most challenging applications. The unique self-cleaning propeller is designed for where the treated mass must be kept in a homogeneous state without dispersing the characteristic gasses used for biogas.
