1. A pump comprising:

  • a reservoir configured to receive a fluid pressurized at a first pressure by a boost pump;

    at least one pumping mechanism including a drive mechanism and an outlet check valve, the at least one pumping mechanism being configured to receive a first flow of fluid from the reservoir and direct the first flow of fluid into a discharge passage of the pump without pressurizing the first flow of fluid above the first pressure when priming the pump, the at least one pumping mechanism being disposed in the reservoir such that the fluid in the reservoir surrounds at least a portion of the at least one pumping mechanism, the discharge passage being configured to output the first flow of fluid from the pump, the outlet check valve being configured to close preventing the first flow of fluid when a pressure in the discharge passage is substantially equal to the first pressure;

    a bypass passage configured to communicate a second flow of fluid from the reservoir to a storage tank; and

    a sensor configured to determine a temperature associated with the pump, the sensor being in communication with a controller, when the determined temperature is equal to or below a threshold temperature the controller is configured to stop riming the pump by starting the drive mechanism so that the at least one pumping mechanism begins pressurizing the first flow of fluid from the reservoir into the discharge passage at a second pressure greater than the first pressure.
