  1. Hydraulic Components Advanced Hydraulics Don Gilliland

  2. Hydraulic Components • Reservoirs • Accumulators • Pumps • Valves • Actuators • Conductors

  3. Hydraulic Components • Pump Functions • Create Flow • Maintain Flow against Load • Load  Flow = Pressure • Volume Under Pressure Per Unit of Time  GPM@PSI

  4. Hydraulic Components • Pump Construction Types • Gear • Piston • Vane • Rotor • Lobe

  5. Pump Construction Types • Gear Pump Types • External Gear w/o glands • External Gear w/ glands • Internal Gear (Crescent) • Maybe w/ or w/o glands • Gerotor (Modified Int. Gear/Rotor) Note 1: 2nd ½ of this video is Gerotor Note 2: Click on each brown type above for demos

  6. Pump Construction Types • Gear Pump Types • External Gear w/ glands

  7. Hydraulic Components • Pump Construction Types • Gear • Piston • Vane • Rotor • Lobe

  8. Pump Construction Types • Piston Pump Types • Radial (John Deere and Massey) • Radial (Push In) • Axial (Bent Axis) • Axial (Swash Plate) • Axial (Wobble Plate) Note: Click on each brown type above for demos

  9. Pump Construction Types • Piston Pump Types • Radial (John Deere and Massey) High Capacity (GPM) Double Pump for: Construction Equipment

  10. Pump Construction Types • Piston Pump Types • Axial (Pressure Compensated) • Axial (Cylindrical Energy Module) (Scroll down for live animation) • Axial (Wolfhart Principle) Notes: • Click on each brown type above for demos • Click On: Animated Pump Glossary for reference
