VEVOR 4 Quart Hydraulic Power Unit, Double Acting Dump Trailer Pump, 3200 PSI Max Relief Pressure & 0.91 GPM Flow Rate, DC 12V Hydraulic Pump with Metal Reservoir for Dump Trailer Car Lifting, Black

DC 12V, 1.6 kW Motor Drives Double Acting Hydraulic Power Unit to 3,200 PSI Relief Pressure

The VEVOR double acting hydraulic power unit features a DC 12V, 1.6 kW motor designed to deliver steady, high-force output during tough lift and lower cycles. This unit works at a pressure range of 16 to 20 MPa and has a maximum relief pressure of 3,200 psi. It gives heavy-lift equipment the steady, confident force it needs to handle heavy loads on job sites and in workshops with minimal pressure fluctuation.

At a flow rate of 0.91 GPM, hydraulic fluid moves quickly through the entire circuit, enabling the actuators to respond quickly and experience minimal lag during both the extend and retract strokes. The pump is great for jobs where both load control accuracy and cycle speed are important, such as dump trailer beds and scissor lift platforms that handle different weights.

Double Acting Hydraulic Power Unit Controls Both Raise and Lower Strokes with Pinpoint Precision

This double acting hydraulic power unit powers both extension and retraction of the cylinder, unlike single-acting systems that rely on gravity for the return stroke. It gives operators precise, predictable control over the entire range of cylinder movement. This is especially important in situations like car lifting, liftgates, and tipping bodies, where controlled lowering is just as important as the raise stroke.

Active control in both directions also reduces cycle time compared to gravity-return systems. This is especially true when the load alone isn’t enough to achieve a fast, steady retract stroke. The result is smoother operation, less mechanical shock on cylinder seals at the end of the stroke, and more consistent positioning accuracy across all operating cycles during the workday.

Built-In Relief Valve Auto-Regulates Double-Acting Dump Trailer Pump Pressure at 3,200 PSI

The built-in relief valve monitors system pressure continuously and releases excess pressure as soon as it exceeds 3,200 psi. This real-time pressure management helps prevent pump damage, hose bursts, and cylinder seal failure when there are sudden changes in load, blocked cylinder travel, or operator mistakes during high-demand lifting sequences.

For a double acting hydraulic power unit, it is very important to have overpressure protection on both the extend and retract circuits. It is because an active force is applied in both directions. The relief valve architecture works in both stroke directions, keeping the whole hydraulic circuit within the rated 16–20 MPa working range. This significantly lowers the chance of parts failing during long, back-to-back operating cycles.

Rust-Resistant Steel Tank and 4-Quart Capacity Support Long-Run Double Acting Pump Reliability

The 4-quart steel reservoir holds enough fluid to keep double acting pump cycles running for a long time without the risk of cavitation or thermal buildup. This rust-resistant steel construction stays strong even when it vibrates, gets hit, and experiences the temperature changes common in mobile dump trailers and job sites. Plastic tanks can be more prone to warping under heat or impact.

A larger amount of fluid also helps with thermal management by making the hydraulic fluid itself a better heat sink. It helps maintain a stable operating temperature across multiple consecutive lift-and-lower cycles. It extends the life of seal and pump components while also shortening maintenance intervals, saving valuable working hours on busy commercial schedules.

Pre-Assembled Design with SAE #6 Fittings Simplifies Installation

This hydraulic power unit comes fully assembled, with the pump, motor, valve block, and reservoir all in one ready-to-mount unit. Setting up is easy: fill the reservoir with hydraulic oil, connect two power leads to the DC 12V source, and attach the hydraulic hoses. No specialized skills or tools are typically needed for this installation.

SAE #6 standard fittings work with the most common sizes of hydraulic hoses used in dump trailers, liftgates, and shop equipment. Reducing the need for adapters reduces potential leak points, speeds up part delivery, and makes it easier to access for future maintenance. This plug-and-go design means that operators with tight installation schedules can get things up and running faster and get back to work sooner.

Efficient Oil Usage in Double-Acting Configuration Reduces Fluid Consumption Per Cycle

One benefit of double acting hydraulic operation over single-acting systems is that it uses less hydraulic oil per work cycle. The system uses only the exact amount of fluid needed for each stroke because the cylinder bore is actively driven in both directions through controlled fluid displacement. This means the circuit isn’t typically flooded to compensate for inconsistencies in the return direction caused by gravity.

By using less fluid per cycle, you may not have to fill up the reservoir as often, the fluid doesn’t break down as quickly from heat and contamination cycling, and the hydraulic system’s total operating cost stays lower over its lifetime. This efficiency advantage can add up to meaningful savings over weeks and months of continuous use for operators who run multiple shifts or applications with many cycles, such as bucket conveyors and small-press operations.

Versatile for Dump Trailers, Lifts, Presses, and Conveyors

This VEVOR double acting hydraulic power unit can meet the needs of dump trailers, liftgates, scissor lift platforms, lift tables, small shop presses, and bucket conveyors, all in one compact unit. It has a maximum pressure of 3,200 psi and a flow rate of 0.91 GPM. The double-acting valve design means it can be used in many situations where you need to control a cylinder in both directions without adding additional valve hardware.

Because it works with many types of compatible hydraulic equipment, this unit can be a good investment for contractors, fleet operators, and workshop owners who use a wide range of hydraulic tools. Instead of buying separate power units for each machine, you can install or move a single compatible VEVOR unit between applications as needed. It is designed to operate at its rated level, whether mounted on a trailer chassis or bolted to a shop-floor press frame.
