ABSTRACT:
A constant pressure system for pumping a coal slurry includes a slurry pump mechanically driven by a hydraulic motor which, in turn, is driven by a hydraulic pump. The output of the hydraulic pump is controlled by a pressure sensitive flow control valve that maintains the hydraulic fluid pressure drop as a constant across the hydraulic motor. The system assures a constant hydraulic motor output torque, driving the slurry pump at a constant delivery pressure.
