Abstract
A fluid pump having at least two pump heads in series permits pumping fluid at both high pressure and high volumetric rate. Each pump head has at least two fluid conduits in fluid communication with a housing, the housing containing an impeller for drawing fluid through an inlet in the housing and moving the fluid through the fluid conduits. The at least two fluid conduits of one pump head combine fluid flow at the inlet of a neighboring pump head to provide a single flow of fluid through the inlet into the neighboring pump head. A drive structure passing through the inlets between two pump heads is configured to commonly drive the impellers in the housing of each pump head.
