The HA2F/1~5 Series Axial Piston Pump is a high-performance closed-loop swashplate pump/motor designed exclusively for metallurgical equipment. With a maximum speed of 7500 rpm and advanced spherical oil distribution, it ensures high efficiency, strong impact resistance, and long service life. This series is widely applied in rolling mills, continuous casting machines, and hydraulic drive devices, providing reliable hydraulic power under extreme pressure conditions.
Rolling Mills: Stable hydraulic power for precise control of rolling processes.
Continuous Casting Machines: Ensures reliable flow and pressure for continuous steel casting.
Hydraulic Drive Devices: Powers heavy-duty metallurgical machinery requiring high torque and efficiency.
High Speed Capability: Maximum speed up to 7500 rpm for dynamic metallurgical operations.
Variable Displacement: Stepless flow adjustment through swashplate angle control.
Durable Design: Engineered with high-strength materials for long service life.
High Efficiency: Spherical oil distribution with automatic alignment minimizes leakage.
Bidirectional Energy Conversion: Operates as both pump and motor for versatile system design.
Impact Resistance: Drive shaft supports radial loads, ensuring stable performance in heavy-duty conditions.
