ChangJia piston pumps present a versatile array of capabilities, catering to both open-and closed-circuit systems in medium-to heavy-duty industrial scenarios. The fixed-displacement variants boast outstanding volumetric and mechanical efficiencies. Meanwhile, the variable - displacement models afford you the flexibility to select control options, precisely aligning with specific pressure and flow requirements.

ChangJia hydraulic steering unit is a critical component in agricultural machinery, enabling precise control of direction through pressurized hydraulic fluid. It converts mechanical input from the steering wheel into hydraulic force, reducing manual effort and providing smooth, responsive maneuverability. This system is widely used in agricultural machinery due to its reliability, durability, and ability to handle high loads. Hydraulic steering ensures safety and efficiency, even in demanding conditions, by delivering consistent performance and reducing operator fatigue.
