Electric Powered Hydraulic Pump
Sustained High-Pressure Output Hub
Continuous underground tensioning operations place significant stress on hydraulic power sources. The Electric Powered Hydraulic Pump uses a large-capacity aluminum alloy oil tank paired with an efficient air-cooled radiator to manage oil temperature during extended runs. The built-in radial or axial plunger pump structure generates steady pressure for tensioning jacks. This arrangement prevents overheating from degrading the hydraulic seals.
Thermal Management and Leak Prevention
Feature 1: The large oil reservoir and forced air-cooling system maintain hydraulic oil within an optimal temperature range, even during high-frequency tensioning tasks in summer or under full load.
Feature 2: The control valve group uses a manifold design, integrating external piping connections inside the block. This configuration reduces potential leak paths under high pressure and keeps the pump station clean.
Feature 3: The pressure gauge features a shock-absorbing movement. During heavy vibration from pump operation, the pointer provides stable and accurate pressure readings.

Operational Roles
As a central hydraulic source in main roadways or mechanized chambers, the Electric Powered Hydraulic Pump supports multiple tensioning jacks or anchor removal devices. In high-frequency development headings, it replaces pneumatic pumps where rapid pressure buildup is required. On the surface, it drives standard power for prestressed component testing in manufacturing workshops.
Maintenance and Delivery
Customization spans motor power (1.5 kW to 3 kW), voltage and frequency, tank capacity, and valve types, with sample lead times of one to three months. Every unit must pass overpressure holding and continuous operation tests before dispatch. Packaging uses solid wood crates with internal shock-absorbing pads. The pump ships with a quality inspection report and operation manual. Standard models are kept in stock for quick dispatch.
Procurement Inquiries
Q1: What pre-operation checks are necessary?
A1: Verify the oil level is within the indicator range (46# anti-wear hydraulic oil recommended), check hose connections for tightness, and confirm the power supply matches the motor nameplate. Jog the motor to verify correct rotation.
Q2: Can noise be reduced further?
A2: Yes. Standard equipment operates under 85 dB. For sites requiring lower noise, custom soundproof covers or low-noise pump groups can be configured.
