Abstract

A pump assembly comprises a housing 50 and a plurality of jet pumps 52 arranged in parallel within the housing which is preferably of Tee form and includes a high pressure HP inlet 54, a low pressure LP inlet 58 on the branch of the Tee and an outlet 56 in line with the inlet. The housing is divided internally by bulkheads 68, 70 into an HP zone 62, an LP zone 64 and an outlet zone 66. Each jet pump is standardized and includes a nozzle, a mixing tube and a diffuser, and has a HP inlet located in the HP zone, a LP inlet located in the LP zone, and an outlet located in the outlet zone. Any of the jet pump inlets are pluggable by either a manually screw-in plug or a remotely operated hydraulic valve to vary the number of operating jet pumps and thus capacity. The pumps may be of different sizes or optimized for different flow conditions. Used subsea or offshore.
