RAM PREMIUM Double Acting Hydraulic Pump for Dump Trailers
The RAM PREMIUM unit is a compact, double-acting hydraulic power unit designed for dump trailers and tilt-decks. It operates from a 12-volt deep-cycle RV or marine trailer battery (not supplied) and includes a 4-quart reservoir. With a 1.6 kW, 12V DC motor, this pump provides reliable performance for lifting and lowering loads. The dual-acting mechanism ensures smooth, balanced operations, with straightforward wiring for on-trailer installation.
VEVOR 8 Quart Hydraulic Power Unit
VEVOR’s hydraulic pump features a 12V, 1.6 kW motor, delivering up to 0.91 GPM. It uses an 8-quart reservoir and can generate up to 3200 psi, enabling heavy-duty lifting for dump trailers and machinery. The double-acting design ensures even force distribution, and the unit includes a built-in safety relief valve for overpressure protection. It arrives pre-assembled, with SAE #6 connectors for broad compatibility.
Mophorn 20 Quart Hydraulic Power Unit (Slaige)
The Mophorn 20 Quart hydraulic power unit is a double-acting system powered by a 12V DC motor, with a robust 20-quart reservoir. It supports up to 3200 PSI on the primary SAE#6 ports and includes ample documentation, a 15-foot remote control, and extra SAE #6 connectors. Its steel reservoir helps resist cracking and leaks, making it a solid replacement for remote hydraulic systems in dump trailers.
VAIDPRO Hydraulic Pump 12V 3 Quart
VAIDPRO offers a compact 3-quart reservoir with a 12V double-acting hydraulic pump. It features a high relief setting up to 3200 psi on port A and 1500 psi on port B, plus a simple setup with two SAE #6 connectors and a 15-foot remote control. The design emphasizes quick start and reliable performance for smaller dump trailers or auxiliary lifting tasks.
Nakkaa 12V DC Hydraulic Power Device
The Nakkaa 12V DC hydraulic power device combines an 8-quart reservoir with a 1.6 kW motor. It features a maximum relief setting of 3200 PSI (A port) and 1500 PSI (B port), plus a 15-foot remote. The unit uses a rugged metal tank for durability and aims for fast activation and reliable lifting for dump trailers and similar equipment.
Buying Guide
When selecting a hydraulic pump for a dump trailer, consider the following factors to ensure compatibility and safe operation:
- Reservoir size: Larger reservoirs (e.g., 8–20 quarts) reduce heat buildup and provide more continuous lifting cycles, which is useful for larger trailers or frequent dumps.
- Max pressure: Most dump trailers require up to 3200 PSI. Ensure the port configuration (SAE #6) and relief valves match your system’s needs.
- Power source: All listed options use 12V DC, typical for on-trailer batteries. Verify battery capacity and wiring gauge to support peak current without voltage drop.
- Double-acting design: This feature provides simultaneous control during lift and lower, improving stability and speed of operation.
- Safety and controls: Look for built-in relief valves and a remote control option for safer operation and distance control.
- Installation compatibility: SAE connectors and port configurations affect compatibility with existing hoses and manifolds. Pre-assembled units reduce install time.
- Durability: Metal reservoirs and rugged housings reduce wear and prevent leaks—especially important under heavy-duty use and outdoor conditions.
- Remote operation: A longer remote can improve control during dumps and positioning, minimizing manual handling near the load.
Comparative considerations:
- Best overall performance: Units with 8–20 quart reservoirs and >0.9 GPM flow balance power with durability for frequent dumps.
- Compact setups: Smaller reservoirs (3–4 quarts) suit lightweight trailers or spaces with tight mounting allows.
- Ease of setup: Pre-assembled units with SAE connectors and remote controls save time and reduce wiring complexity.
- Reliability: Safety relief valves and sturdy metal tanks help prevent overpressure and oil leaks during heavy operations.
In summary, the top options provide a range of reservoir capacities and power to fit different dump trailer sizes and work requirements. Assess your trailer’s payload, cycle frequency, and available mounting space to pick the most suitable hydraulic pump.
