The DPM is available in sizes from 1/2 pint to 750 gallons. Unit can incorporate the patented “HV” blade design. This blade configuration allows use of the mixer for materials having a viscosity up to approximately 6 million centipoise. The blade was designed to produce excellent axial and radial flow, while operating at close blade to bowl clearance. The close blade to bowl design prevents the buildup of material on the tank wall and ensures efficient heat transfer when used with a jacketed mixing vessel.
