The Piston Pump is a component that provides the primary hydraulic power for operating various systems and functions in the vehicle. It has a variable displacement pump designed to deliver high-pressure hydraulic fluid to different hydraulic system parts. The pump is usually driven by an engine or a power take-off unit, which transfers mechanical power to the pump drive shaft. As the drive shaft rotates, it causes the cylinder block and pistons to reciprocate. This reciprocating motion creates suction and compression strokes, allowing the pump to draw in hydraulic fluid and deliver it at high pressure.

Attributes:
• Built to handle heavy loads, vibrations, and shocks.
• Designed to deliver high-pressure hydraulic fluid.
• Displacement: 71 cc/rev.

Applications:
The Piston Pump is used in the hydraulic fan system. It is designed to control the cooling airflow.
