Abstract

A thrust module and a seal module for use in an electric submersible pump assembly is provided. The thrust module provides increased lubrication and heat dissipation while increasing sealing redundancies within the module. The thrust module includes a thrust bearing that absorbs thrust from the primary pump. A circulation pump assembly is coupled to the thrust bearing to circulate fluid through the thrust bearing and dissipate heat generated in the thrust bearing through a plurality of fins formed on an exterior surface of the circulation pump assembly. The seal module has labyrinth discs positioned within the seal module that inhibit fluid flow through the seal module. The seal module also includes check valves that release fluid from and allow fluid into the seal module at predetermined pressures. The sealing assembly is interposed between the thrust bearing and a primary pump of the electric submersible pump.
