A centrifugal charge pump is upstream from the gas separator. The charge pump has charge pump stages and a discharge that leads to an intake of the gas separator. Each of the production pump stages has a higher lifting capacity than each of the charge pump stages. The impellers of the production pump stages have vane exit angles greater than vane exit angles of the impellers of the charge pump stages.
