摘要： A multi-stage fluid pump system can include a first stage configured to provide a first pressure and a second stage configured to provide a second pressure. The pump system can be configured to prevent output of the second stage in a first stage mode such that only the first pressure is output from the first stage and second stage and to allow output of the second stage in a multi-stage mode such that there is a combined pressure output from the first stage and the second stage.

摘要： A fluid conditioning module having a fluid inlet and a fluid outlet is provided. The fluid conditioning module includes a first pump element, a second pump element, a pressure regulator, a controller, and a prime mover to impart rotational motion in the first and second pump elements. A first pump inlet is in fluid communication with the fluid inlet. A filter inlet is in fluid communication with a first pump outlet and a second pump outlet, and a filter outlet is in fluid communication with the fluid outlet. A pressure regulator inlet and a pressure regulator outlet are in fluid communication with the filter outlet and a recirculation conduit, respectively. The control valve has a first position and a second position, which allows fluid flow through the recirculation conduit. The controller adjusts operation of one or more of the prime mover and the control valve based upon a predetermined parameter.
