A4FO Series Hydraulic Pump A4FO28/32R-NSC12N00 A4FO500/30R-PZH25N00 A4FO71/10R-PPB25N00 Piston Pump

Stable Constant Flow Output: Fixed displacement structure ensures linear and stable flow output matching driving speed, with minimal pressure fluctuation. It effectively eliminates system jitter and pressure drop under variable load conditions, ensuring precise and consistent operation of hydraulic actuators.
Heavy-Duty High-Pressure Resistance: All models adopt upgraded internal pressure-bearing structure and high-strength alloy core components. They support long-term stable high-pressure operation, fully meeting the power demands of light, medium and heavy-load hydraulic equipment scenarios.
High Energy Efficiency: Optimized smooth internal flow channels reduce fluid resistance and mechanical friction loss. Excellent volumetric and mechanical efficiency lowers power consumption during long-duration continuous operation, improving the overall energy utilization of hydraulic systems.
