Spin-resistant diffuser for electric submersible pump

Abstract

A diffuser stack for a centrifugal pump includes a first diffuser including a first rim having a first inner circumferential surface, a first outer circumferential surface, and protrusions extending radially inward from the first inner circumferential surface. The diffuser stack further includes a second diffuser including a second rim having a second inner circumferential surface and a second outer circumferential surface. Recesses are formed in the second diffuser. The recesses extend radially inward from the second outer circumferential surface. The second diffuser is configured to engage the first diffuser such that the second outer circumferential surface engages the first inner circumferential surface and the protrusions engage the recesses.
