How the THM A4VG Pump Works:-

The pump achieves precise hydraulic control without ever needing to stop the system:

• Swash Plate Mechanism: A rotating cylinder block houses multiple pistons. The swash plate dictates the stroke length of these pistons—steep angles increase fluid output, flat angles decrease it, and a zero-degree angle halts flow completely.
• Suction & Compression: As pistons retract, they draw hydraulic fluid into the chambers. As they push forward, they compress the fluid and force it through the high-pressure outlet, enabling flawless hydrostatic drive performance.

Ideal Industry Applications:-

Thanks to its self-priming capabilities, built-in charge pump compatibility, and through-drive coupling, the A4VG is the ultimate power source for:

• Excavators, Cranes, and Loaders
• Road Construction Machinery
• Agricultural Harvesters
• Heavy-Duty Hydraulic Power Units
