A typical hydraulic pump consists of the following key parts:

  • Housing/Casing – Protects internal components and maintains structural integrity.

  • Drive Shaft – Transmits power from the engine to the pump mechanism.

  • Rotating Group (Gears, Pistons, or Vanes) – Generates fluid flow and pressure.

  • Inlet & Outlet Ports – Allow hydraulic fluid to enter and exit the pump.

  • Pressure Relief Valve – Prevents system overload by diverting excess fluid.

  • Seals & Bearings – Ensure leak-free operation and reduce friction.
