VEVOR 4 Quart Hydraulic Power Unit, Single 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

DC 12V, 1.6 kW Motor Powers Single Acting Hydraulic Pump for Dump Trailer to 3,200 PSI Relief Pressure

The VEVOR hydraulic power unit features a 12V DC, 1.6 kW motor that lifts heavy loads without an external power source. This unit can handle heavy loads with a maximum relief pressure of 3,200 psi and a working pressure range of 16 to 20 MPa. Operators can count on it to deliver consistent, stable force output even in tough job-site conditions.

The pump moves hydraulic fluid through the circuit quickly at a flow rate of 0.91 GPM. It ensures that actuators respond quickly and that there is minimal pressure drop during long-term operation. This level of performance gives operators precise control over dump-trailer cylinders and scissor lifts while maintaining the pressure headroom needed for safe, repeatable heavy-duty lifting cycles.

4-Quart Metal Reservoir Supports Extended Operation

The 4-quart hydraulic reservoir holds enough fluid to keep the pump running without overheating or cavitating for extended periods. The tank is made of strong metal that can withstand daily bumps, vibrations, and the physical stress of being in a mobile dump trailer or liftgate, where equipment is always getting beaten up.

A larger reservoir also helps the heat spread more evenly, keeping the fluid temperature stable during multiple lift-and-lower cycles. It helps extend the seals’ service life, protects the pump’s internal components, and reduces maintenance requirements. These are all very important benefits when equipment has to work on a tight schedule and can’t afford to be down.

Built-In Relief Valve Keeps Pressure Auto-Regulated at 3,200 PSI

The built-in relief valve is an important safety and performance feature that releases excess pressure when the system exceeds the set 3,200 psi limit. It prevents pressure spikes caused by sudden load shifts or operator mistakes in high-demand situations from damaging pumps, blowing hoses, or breaking cylinder seals.

The relief valve also protects downstream components such as cylinders, fittings, and control valves by keeping pressure within the calibrated working range of 16–20 MPa. There is no need to manually check pressure at each lift cycle, which is a big plus for single-operator dump-trailer setups.

Pre-Assembled Design with SAE #6 Fittings, Cuts Single Acting Hydraulic Pump For Dump Trailer Install Time

This single acting hydraulic pump for dump trailer comes fully assembled, with the pump, motor, valve block, and reservoir ready for mounting. To install, all you have to do is add hydraulic oil, connect the two power leads, and attach the hydraulic hoses. It is a simple process that operators without specialized hydraulic system training can perform.

The SAE #6 standard fittings are compatible with the most common hydraulic hose sizes in the industry. Most standard dump-trailer setups often don’t require additional adapters or custom fittings. It lowers parts costs, eliminates leak points at adapter joints, and gets the hydraulic circuit up and running much faster than systems that require custom plumbing.

Gravity-Return Single-Acting Operation Delivers Reliable Raise and Controlled Lower Cycles

In single-acting hydraulic operation, the pump actively moves the cylinder in one direction, the raise stroke, while gravity controls the return on the lower stroke. This design simplifies the valve, reduces the number of potential failure points, and is a common industry choice for dump trailer beds, liftgates, and tipping bodies.

The gravity-return mechanism also reduces pump runtime and electrical draw because the motor runs only during the pressurized rise cycle. For DC 12V vehicle-mounted systems where battery load management is important, this efficiency means each operation uses less current and puts less stress on the truck or trailer’s charging system throughout a full workday.

Versatile 12V Hydraulic Pump Rated for Dump Trailers, Scissor Lifts, and Small Press Applications

This single acting hydraulic pump for dump trailer can be used for more than just dump trailers. It can also be used for liftgates, scissor lift platforms, lift tables, small shop presses, and bucket conveyors. This feature makes it a truly multi-purpose investment for contractors and workshop owners. The maximum pressure of 3,200 psi and the flow rate of 0.91 GPM are enough for most of these types of equipment to work.

This flexibility means that you don’t have to buy separate hydraulic power sources for each machine in a shop or fleet. You can move a single VEVOR unit from one job to another as needed, and it will work the same whether it’s permanently mounted on a trailer or temporarily attached to a press for batch production work.

Leak-Resistant Seals and Durable Tank Construction Ensure Long-Term Hydraulic System Reliability

The single acting hydraulic pump for dump trailer assembly has precision-fitted seals at all valve blocks and cylinder connections. These seals are designed to keep the hydraulic circuit tight even when the pressure and temperature change. Leak resistance is important in mobile equipment like dump trailers because fluid loss reduces performance, pollutes the environment, and accelerates internal wear.

The tank is built to last and can withstand the bumps, vibrations, and rough handling common on job sites and during road transport. The reservoir’s long-term structural integrity helps keep the fluid clean and limit contaminants, protecting the pump internals, extending component service intervals, and keeping the hydraulic system running near its intended capacity long after it was first installed.
