Three-Phase Continuous Duty Industrial Hydraulic Power Unit
Engineered for fixed industrial equipment requiring stable, around-the-clock operation. This AC hydraulic power unit combines a three-phase TEFC motor with an external gear pump to deliver reliable hydraulic power for presses, machine tools, and automation systems.
Key Selling Points
Continuous-Duty Motor - The TEFC AC induction motor is available in continuous-duty configuration, ensuring sustained operation without overheating for critical production processes.
High-Pressure Capability - Maximum working pressure of 230 bar (3,335 PSI) allows the unit to power demanding hydraulic actuators in industrial machinery.
Flexible Control Interfaces - Compatible with PLC, HMI, remote control, and manual controls for seamless integration into automated production lines.
Customizable Configurations - Custom reservoirs, mounting frames, manifolds, and electrical cabinets are available to match machine-specific requirements.
Rigorous Testing - Each unit undergoes pressure, leakage, electrical, and full-function testing before shipment to ensure reliability.
