Both statements are correct. Most hydraulic circuits indeed use positive displacement pumps because they can efficiently maintain the flow necessary for the system's operation. Technician B is also correct in stating that pressure in a hydraulic circuit only results when there is some form of resistance to flow, which is fundamental to how hydraulic systems operate.
