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, White

VEVOR Hydraulic Dump Trailer Pump Delivers 3,200 PSI at 0.91 GPM with 1.6 kW Motor

The VEVOR hydraulic dump trailer pump operates at 16-20 MPa and can relieve up to 3,200 PSI. This feature gives it the power to lift heavy dump-trailer cylinders, liftgates, and scissor lifts when fully loaded. The pump moves hydraulic fluid steadily through the circuit at a flow rate of 0.91 GPM, without any pressure drops or cavitation, when running continuously. This combination of pressure and flow provides double-acting cylinders with smooth, controlled actuation throughout the stroke.

The unit is powered by a 1.6 kW DC motor that runs on a standard 12-volt electrical system. It draws power directly from the vehicle or trailer battery, so it doesn't need an external power source or generator. This 12-volt compatibility means it can be used right away on trucks, work vehicles, and trailer rigs already at the job site. 

Double-Acting Dump Trailer Pump Controls Powered Raise and Lower with Built-In Relief Valve

Instead of relying on gravity or spring return to pull the cylinder back, the double-acting configuration gives powered hydraulic control in both directions, up and down. This bidirectional force delivery lets you place the load exactly where you want it at any point in the cylinder's travel. It is important for dump trailers that need to unload on uneven ground or scissor lifts that need to stop in the middle of a stroke. 

When loads exceed 3,200 PSI, the built-in relief valve automatically releases excess circuit pressure. It sends fluid back to the reservoir before the hose breaks, the fitting blows out, or the cylinder seal gets damaged. This passive overpressure protection operates automatically during every work cycle, keeping the system safe even when loads exceed expectations. 

Hydraulic Dump Trailer Pump 4-Quart Durable Plastic Reservoir Withstands Daily Bumps on Trailers and Job Sites

The 4-quart hydraulic reservoir holds enough fluid for normal dump-trailer raise-and-lower cycles, while keeping the whole unit small and light so it can be moved easily. The plastic tank is built to resist the rust and corrosion that steel tanks experience when exposed to road moisture, pool water, and chemicals in farming and building settings. 

Tight seals on all reservoir joints and port connections keep hydraulic fluid from leaking out when mobile applications vibrate and change temperature. Fluid loss in hydraulic circuits slowly lowers system pressure, causing pump cavitation and accelerating wear and tear on internal parts. The sealed plastic reservoir keeps the pump running at the correct pressure without adding fluid between jobs. 

Pre-Assembled Hydraulic Pump with SAE #6 Fittings Installs in Three Steps

This hydraulic dump trailer pump comes fully assembled, so you don't have to spend time putting it together like with hydraulic power unit kits that come in parts. To install it, you need to fill the reservoir with hydraulic oil, connect the power leads to the 12-volt source, and attach hydraulic hoses to the SAE #6 port fittings. 

SAE #6 fittings work with the most common standard for connecting hydraulic hoses in the agricultural, automotive, and industrial supply channels. Most places that sell equipment have replacement hoses and adapters in stock, so you don't have to order them or make them yourself. Operators who want to add this pump to an existing dump-trailer hydraulic circuit can do so without any extra adapters, as the SAE #6 ports connect directly to standard line sizes already in most trailer plumbing setups.

16–20 MPa Working Pressure Powers Dump Trailers, Scissor Lifts, and Liftgates

Dump trailers, liftgates, scissor lifts, lift tables, small shop presses, and bucket conveyors all need between 16 and 20 MPa of working pressure. This power unit can provide all of these needs. Because this pump can be used with many different types of equipment in a shop or on a job site, it reduces the cost of maintaining separate hydraulic power sources for each machine.

For dump trailers, the pressure and flow combination works with both single-ram and twin-cylinder setups common on 5- to 14-foot-long trailer beds. The 1.6 kW motor can run on a 12-volt battery without upgrading the alternator to handle more power. Because this hydraulic dump trailer pump is compatible with existing trailer power systems, it can be plugged right in without needing any extra electrical hardware or wiring changes.

Leak-Resistant Seals and Relief Valve Protect the Hydraulic System Under Continuous Load

The pump body and reservoir connections are sealed with leak-resistant seals to keep fluid from leaking out when the pump vibrates and the temperature changes, which is common in mobile hydraulic applications. Progressive fluid loss can lower circuit pressure, cause the pump to cavitate, and accelerate wear on internal sealing surfaces. All of these things shorten the service life and increase the need for repairs. 

The built-in relief valve opens at 3,200 PSI, sending fluid to the reservoir rather than allowing the circuit pressure to rise above safe levels. This protection works automatically without requiring the operator to adjust it or check an external pressure switch. Even when the payload weight changes from job to job or the load shifts unexpectedly during unloading, the equipment lasts longer, and the operator stays safe.

DC 12V Electric Hydraulic Pump Serves Shop and Field Applications Year-Round

This hydraulic dump trailer pump requires 12 volts of DC power, which is the same as most vehicles and trailers use on construction sites, farms, landscaping jobs, and municipal fleet operations. It connects directly to the 12-volt source on any compatible work vehicle or trailer rig. This plug-and-play compatibility means that the unit can be used right away at remote job sites without any power infrastructure.

The pump can handle both light-precision tasks on lift tables and full-load actuation on commercial dump-trailer cylinders. It has a flow rate of 0.91 GPM and a maximum pressure of 3,200 PSI. The 4-quart reservoir is perfect for small-trailer installations where space is limited, and equipment can't be too large.
