  • Modular thrust-compensating rotor assembly
    Patent number: 10641264
    Abstract: A modular rotor assembly for a screw pump including a power rotor and an idler rotor having respective first ends adapted to be disposed in a suction side of the screw pump and respective second ends adapted to be disposed in a discharge side of the screw pump, the power rotor including a balance piston adapted to be disposed within a pump housing of the screw pump with a radial clearance between an entire circumference of the balance piston and the pump housing is in a range between 1 micron and 200 microns, wherein the power rotor is provided with a tapered bearing surface configured to define a wedge-shaped, radial gap axially intermediate the power rotor and the idler rotor.
