Compact dual-section gear pump
Last updated:
Abstract:
A dual-section gear pump that enhances compactness of the design includes two pump sections separated by a divider. Each pump section includes a pump cavity and a gear set configured to convey fluid from an intake side to a discharge side of the respective pump cavities. The divider includes a fluid flow passage that enables the two pump sections to share common intake flow via the flow passage provided across the divider. The divider also is configured to enable each gear set in each pump section to provide independent pressurization of the fluid in each pump section, which is discharged from each pump cavity via separate outlets. The gear pump is configured to provide suitable sealing between each pump section and support of the respective gear sets in each pump section while enhancing compactness of the design.
