- The S Series Triple-Screw Pump manufactured by Blackmer is a type of positive displacement rotatory pump for handling clear, lubricating liquid without solid content. The internal structure of the Triple-Screw Pump includes a male drive spindle, two female secondary spindles and the case that holds the three screws. The sealed chamber moving at a uniform speed is formed between the case and the three rotating screws along the axial direction. During the male drive screw rotation, liquid moves in the sealed chamber along the axial direction continuously and smoothly from suction to discharge.
