• One Power screw and two Idler screws running in the three precision bores in the housing or liner
• Profiled Screws form a liquid tight seal between the threads
• As the screws rotate, cavities are formed, where liquid gets trapped and conveyed from suction chamber to discharge chamber
• The power rotor does not rotate the idlers. The hydraulic forces acting on screw flanks turn the idlers without torque thus reducing the friction
• The idlers simply roll over the root diameter of power screw and float freely in housing/liner bores
• A balance piston on Power rotor takes care of axial thrusts
• Ball bearing is only for axial positioning of Rotor and safer operation of mechanical seal
