  • Hydraulic Power Pack System
    Publication number: 20220074437
    Abstract: A hydraulic power pack for use in a hydraulic system includes a reservoir configured to receive hydraulic fluid. A pump is in communication with the reservoir and is fluidly connectable to the hydraulic system. The pump is configured to pump hydraulic fluid from the reservoir into the hydraulic system when connected thereto. A hydraulic fluid sensor is fluidly connectable to the hydraulic system to sense a fluid characteristic of the hydraulic fluid within the hydraulic system. A variable speed drive is operatively coupled to the pump and the hydraulic fluid sensor to receive sensor data therefrom, with the variable speed drive being configured to generate a pump control signal based on the received sensor data. The pump is configured to operate at various speeds based on the pump control signal received from the variable speed drive.
