High pressure submersible pump

Abstract

The invention relates to a high-pressure submersible pump with multiple working stages. The pump comprises a fluid inlet and outlet, and an electric motor with a stator and rotor, axially traversed by a shaft extending between a first and second end of the motor. At least one working stage is arranged at each end, each with an impeller fixed to the shaft to increase fluid pressure, and a diffuser that guides the fluid from the impeller. The working stages are connected by at least one conduit that allows fluid to pass between them, ensuring a continuous transfer of hydraulic energy. This configuration improves the hydraulic performance, energy efficiency, and mechanical stability of the system, optimizing its operation under demanding conditions.
