Twin Screw Pump Series
Blackmer Twin Screw Pumps are rotary, positive displacement pumps capable of handling various clean liquids that contain no solids. The pump is composed of two sets of opposed screws. During pump operation, the screws on the two shafts are engaged and form a sealed cavity with the surrounding pump casing. The pumped liquid is shifted axially as the screw shafts turn and steadily and constantly convey the liquid to the center of the pump where the discharge port is located. Since hydraulic forces on two screws are opposite and equal, the hydraulic axial stress on shafts is automatically balanced.

Blackmer Triple Screw Pump
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.
