Abstract: An electrical submersible pumping system (“ESP”) for use in a wellbore includes an electrical motor, a pump, a shaft coupled between the motor and pump, and a lubricant pump for circulating lubricant within the ESP. The lubricant pump includes a diffuser and an impeller that mounts onto and rotates with shaft rotation. A portion of the impeller has a frusto-conical outer surface, which is circumscribed by a portion of the diffuser profiled complementary to the frusto-conical portion of the impeller. The pump directs lubricant flow in a single direction irrespective of the rotational direction of the shaft.
