| Sr. No. | Component Name | Function / Description |
|---|---|---|
| 1 | Prime Mover (Motor) | Provides rotational energy to drive the gearbox. |
| 2 | Gearbox | Reduces speed and increases torque for crank operation. |
| 3 | Crank & Counterbalance Assembly | Converts rotary motion into reciprocating motion and balances dynamic load. |
| 4 | Walking Beam | Acts as a lever transmitting motion from crank to polished rod. |
| 5 | Pitman Arm / Connecting Link | Connects crank assembly to walking beam end. |
| 6 | Bearing Housing / Samson Post | Supports and allows pivot motion of the walking beam. |
| 7 | Horse Head | Curved end of the beam connecting to the polished rod clamp. |
| 8 | Polished Rod | Connects surface unit to the subsurface pump rod string. |
| 9 | Stuffing Box | Seals the wellhead around the moving polished rod to prevent fluid leakage. |
| 10 | Baseplate / Skid Frame | Structural base supporting the entire pumping unit. |
