· ​High-Pressure Dual-Stage Efficiency: Features an automatic dual-stage pumping mechanism that delivers high flow at low pressure for rapid piston advance, and switches to high pressure for precise, heavy-load tensioning.
· ​Precision Pressure Regulation: Equipped with fine-adjustment relief valves and a high-accuracy glycerin-filled pressure gauge, ensuring exact control over hydraulic output and anchor seating forces.
· ​Heavy-Duty Thermal Endurance: Built with an oversized oil reservoir and optional integrated oil cooling systems, preventing thermal overheating during continuous, high-cycle stressing operations.
· ​Full Industrial Safety & Traceability: Manufactured under strict ISO 9001 protocols, incorporating automated over-pressure bypass protection and heavy-duty electrical control boxes for maximum operator safety.
​Engineered as the primary hydraulic power source for a wide range of heavy engineering and manufacturing systems:
· ​Post-Tensioning & Bridge Construction: Powering mono-strand and multi-strand stressing jacks for bridge girders, floor slabs, and containment structures.
· ​Heavy Lifting & Structural Rigging: Driving synchronized hydraulic jacks, bridge lifting systems, and structural alignment pushes.
· ​Industrial Manufacturing & Maintenance: Heavy press machines, flange pullers, and high-pressure test bench equipment.
​Q: What is the maximum operating pressure of this electric oil pump?
A: This unit is engineered to deliver a continuous working pressure of 63 MPa to 70 MPa (9,100 to 10,000 psi), matching the exact operational requirements of standard post-tensioning jacks and heavy cylinders.
​Q: Can the pump be customized for different electrical power supplies?
A: Yes. We offer flexible motor configurations to match global standards, including standard 3-phase voltages such as 380V/50Hz, 415V/50Hz, or 440V/60Hz.
​Q: What is the standard export packaging and transport safety?
A: Each electric oil pump is securely drained, sealed, mounted onto a sturdy fumigated wooden pallet, and enclosed inside a reinforced export wooden crate to prevent any transit damage.
