We design and manufacture advanced Direct Current (DC) motor hydraulic power units, engineered to deliver reliable, efficient hydraulic power in mobile, remote, or off-grid applications where AC mains are unavailable or impractical. Our DC hydraulic power units are precision-built for compactness, portability, and robust duty cycles—making them the ideal solution for material handling, vehicle-mounted systems, lifts, emergency equipment, and industrial automation.
What is a DC Motor Hydraulic Power Unit?
A DC motor hydraulic power unit consists of a high-efficiency, low-voltage electric motor (most commonly 12VDC or 24VDC), a hydraulic pump (gear, vane, or piston type), reservoir, control valves, and all relevant hydraulic, electrical, and electronic components, integrated into a compact assembly. Unlike AC-driven systems, DC units offer true independence from fixed electrical infrastructure, enabling operation from batteries, vehicle power, or renewable energy sources.
Key Technical Features
- DC Electric Motor Options
- Available in 12V, 24V, and sometimes 48V DC configurations.
- Power outputs typically range from 0.35 kW up to 2.2 kW per motor, or higher for custom designs.
- Options for permanent magnet or series wound motors, with CCW/CW rotation as required.
- Motors are rated for intermittent (S2/S3 duty) with startup surges, optimized for use in automotive, industrial, or mobile equipment.
- Hydraulic Pump Specifications
- Gear pumps provide flows from approx. 0.2 to 7.8 cc/rev, supporting typical output flows from 0.3 L/min to 10+ L/min.
- System pressure capabilities up to 207–300 bar (3,000–4,350 psi), with adjustable relief valves to protect the circuit.
- Tank and Reservoir
- Integral or remote reservoirs sized to match required duty cycle and flow—typically 2 to 7.5 liters, but available up to 180 liters for large custom units.
- Integrated oil filters, breathers/fill caps, and oil level/temperature gauges for clean and reliable operation.
- Controls & Valves
- Manual or solenoid-operated directional valves for single/double-acting cylinder operation.
- Optional remote pendant or wireless control, timed run logic, load holding valves, and proportional flow/pressure control.
- Electrical Protection & Safety
- IP54 or higher protection for all electrical components.
- Overload, over-temperature, and short circuit protection built-in.
- Suitable for safe vehicle, trailer, or field mounting.
- Construction & Integration
- Compact and ruggedized steel, aluminum, or ABS enclosures; corrosion protection as required.
- Mounting flexibility (base, side, upright) for integration within machinery, vehicles, or mobile power packs.
Manufacturing Process Overview
- Application Engineering & Sizing
- Duty cycle, load, flow, and pressure requirements specified; battery sizing and charge cycle analysis.
- 3D CAD modeling for space optimization and specification compliance.
- Component Sourcing
- Selection of branded high-torque DC motors, sealed hydraulic pumps, and top-grade valves and electronic control solutions, ensuring safety and lifetime reliability.
- Precision Assembly/Integration
- CNC machining of motor brackets, pump adapters, and tank flanges for warping resistance and alignment.
- Assembly in cleanroom conditions, with careful torque control, crimped terminals, and full hose/pipeline leak testing.
- Functional Testing
- Hydraulic performance (flow, pressure, response time) is validated under simulated real-world loads.
- Electrical testing for start/run current, protection trip, and temperature rise.
- Final QC & Documentation
- Units supplied with connection diagrams, safety warnings, duty limits, and performance certification.
