VEVOR 12 Volt Dump Trailer Hydraulic Pump Delivers 3,200 PSI at 0.91 GPM Flow Rate

The VEVOR 12 volt dump trailer hydraulic pump can operate at pressures between 16 and 20 MPa, with a maximum relief pressure of 3,200 PSI. This feature gives it the power to lift and lower heavy loads on dump trailers, scissor lifts, and liftgates. The pump moves hydraulic fluid through the circuit quickly at a flow rate of 0.91 GPM without cavitation or a pressure drop when the load is on. 

The unit runs on a standard 12-volt vehicle electrical system and has a 1.6 kW DC motor. It gets its power from the same source as trucks, work vehicles, and trailer rigs. This pump can be used in the field right away because it doesn't need an external power source or generator. The fact that it works with 12 volts means it can be used with a wide range of commercial and residential dump-trailer setups.

Double-Acting Hydraulic Dump Trailer Pump Controls Both Raise and Lower Functions

This dump trailer hydraulic pump has a double-acting design that lets you control the pump in both directions, up and down, rather than relying on gravity or spring return for the retraction stroke. This bidirectional control lets you position the cylinder exactly where you want it, which is important for dump trailers that need to unload on uneven ground or scissor lifts that need to stop at different heights. 

When the system load exceeds 3,200 PSI, the built-in relief valve automatically releases excess pressure. It stops hose failure, fitting blowout, and cylinder seal damage when the system is overloaded. This automatic over-pressure protection eliminates a common failure point in double-acting hydraulic circuits operating close to their maximum rated capacity. 

8-Quart Steel Reservoir Sustains Thermal Stability Across Multiple Raise-Lower Cycles

The 8-quart hydraulic reservoir holds enough fluid to keep the pump running for a long time without overheating or running dry at the inlet. A larger reservoir can hold more fluid, allowing the heat from the pumping cycles to spread over a larger volume. It lowers operating temperature and extends the life of the seal and fluid. This thermal buffer is important for dump trailer applications that require multiple raise-lower cycles per shift.

The reservoir is made of rust-resistant steel to withstand dirt, moisture, and mechanical impacts common on trailers and job sites. The tight seals on all reservoir joints and port connections prevent hydraulic fluid from leaking out during system vibration, which is the main reason mobile hydraulic systems lose fluid. The steel construction also maintains its shape when mounted and moved over rough ground.

Pre-Assembled Dump Trailer Hydraulic Pump with SAE #6 Fittings for Fast Installation

This 12 volt dump trailer hydraulic pump comes fully assembled, so you don't have to spend time putting it together on a bench as you do with most component-level hydraulic power unit kits. You only need to do three things to install it: fill the reservoir with hydraulic oil, connect the power leads to the 12-volt source, and attach the hydraulic hoses to the SAE #6 fittings. 

SAE #6 fittings are a common size for hydraulic connections and are compatible with most commercial hydraulic hose assemblies sold at agricultural, industrial, and automotive supply stores. For operators who want to add this pump to an existing trailer hydraulic circuit, the SAE #6 ports connect directly to standard line sizes already in place in most dump-trailer plumbing setups.

12V Hydraulic Power Unit Rated for Dump Trailers, Scissor Lifts, and Liftgates

The 12 volt dump trailer hydraulic pump can handle a maximum pressure of 3,200 PSI, a flow rate of 0.91 GPM, and double-acting cylinder control. These are the same as the hydraulic needs of dump trailers, liftgates, scissor lifts, lift tables, small shop presses, and bucket conveyors. With this range of applications, a single power unit can power multiple pieces of equipment in a shop or on a job site.

The combination of pressure and flow is ideal for dump trailer operators because it works with the cylinders commonly used in 5-14 foot single-ram and twin-cylinder dump configurations. The 1.6 kW motor can run on a 12-volt battery system without needing high-output alternator upgrades on most work trucks.

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

When the circuit pressure reaches 3,200 PSI, the built-in relief valve in this dump trailer hydraulic pump automatically opens, sending fluid back to the reservoir rather than allowing pressure to build to unsafe levels. This passive protection system operates independently, providing consistent overpressure protection throughout every work cycle without the need for manual valve adjustments or external pressure switches.

The pump body and reservoir connections feature leak-resistant seals that prevent fluid leakage during the vibration and thermal cycling that occur when mobile hydraulic applications are used on dump trailers and job site equipment. When hydraulic fluid leaks, the system's performance deteriorates over time. It lowers pressure, causes pump cavitation, and accelerates wear on the inside. 

DC 12 Volt Dump Trailer Hydraulic Pump with 16–20 MPa Working Pressure for Shop and Field Use

This DC 12V electric hydraulic pump can handle the needs of both light shop tools and heavy field machinery without changing pressure between uses. It has a working pressure range of 16 to 20 MPa. At the lower end of its working range, the pump performs precise work on lift tables and small presses, where controlled force is more important than maximum output. At an upper working pressure of 20 MPa, the unit provides the force levels required to move loaded dump-trailer cylinders and commercial liftgates.

The pump's pre-assembled design and standard SAE fitting sizes make it easy to service in the field. It means hoses can be replaced and small repairs can be made without sending the unit back to a shop. The 8-quart reservoir capacity gives operators a practical window for scheduling maintenance, providing enough fluid reserve to find and fix small leaks before they affect system pressure.
