  • BASIC HYDRAULIC SYSTEMS AND COMPONENTS

    The heart of any hydraulic system is the pump which converts mechanical energy into hydraulic energy. The source of mechanical energy may be an electric motor, the engine, or the operator's muscle. Pumps powered by muscle are called hand pumps. They are used in emergencies as backups for power pumps and for ground checks of the hydraulic system.
