Abstract
A multistage centrifugal pump includes an upstream housing and a downstream housing. The upstream housing and the downstream housing each have a first end, a second end and a plurality of turbomachinery stages. Each of the plurality of turbomachinery stages includes a diffuser and an impeller. A compression bulkhead is connected between the second end of the upstream housing and the first end of the downstream housing. The compression bulkhead applies a compressive force to the diffusers within the upstream housing.
