VEVOR 20 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

Dump Trailer Hydraulic Pump with 3,200 PSI Max Relief Pressure for Controlled Heavy Load Operation

This VEVOR dump trailer hydraulic pump can handle heavy loads of aggregate, demolition debris, and construction materials without putting excessive stress on the system. It has a working range of 16 to 20 MPa and a maximum relief pressure of 3,200 PSI. The built-in relief valve releases excess pressure as soon as the system reaches its limits, preventing damage to the parts before it occurs.

This pressure ceiling ensures that full bed raises occur consistently, without pressure drops or actuator hesitation during the cycle. The auto-venting feature means operators don’t have to check system pressure during lift cycles manually. It makes their job easier and protects cylinders, hoses, and fittings from excessive stress.

Double Acting Pump Design Controls Both Raise and Lower Strokes at 0.91 GPM Flow Rate

This double-acting dump trailer hydraulic pump actively controls both extension and retraction strokes through dedicated fluid paths. It differs from single-acting systems that rely on gravity or spring force to pull the cylinder back. The 0.91 GPM flow rate remains constant in both directions, so the cycle times are the same whether the bed is rising under a full load or lowering in a controlled manner.

This two-way control is very helpful on liftgates and scissor lifts, where an uncontrolled retraction stroke can be dangerous. The steady 0.91 GPM output also reduces the thermal load per cycle because the fluid is actively routed rather than simply returning freely. It keeps the operating temperatures stable throughout the day, even after many lift sequences.

DC 12V, 1.6 kW Motor Powers the Hydraulic Pump Directly from Standard Vehicle Battery Systems

This hydraulic power unit’s DC 12V electrical system can be plugged directly into the batteries of standard trucks, trailers, or equipment without needing inverters, generators, or other power conversion hardware. The 1.6 kW motor has enough torque to maintain full flow rate output even when the engine is cold and when the load changes during the operating cycle.

This voltage setup lets the unit be used right away on most dump trailers or service vehicles with a 12V system, without modifying the existing electrical system. The 12V motor draws cleanly from the battery without the voltage changes that affect higher-voltage pump setups in mobile applications, so operators who work at multiple job sites can count on consistent startup performance no matter the outside temperature.

20 Quart Rust-Resistant Steel Reservoir Sustains Extended Duty Cycles Without Thermal Overload

The 20-quart metal reservoir holds a lot more fluid than standard 8 or 12 quart units. It helps prevent heat buildup during high frequency lift operations and prevents the pump inlet from running dry during high demand. This larger capacity helps maintain the hydraulic fluid’s viscosity within the optimal range, enabling longer, uninterrupted run times.

The tank is made of rust-resistant steel, so it stays strong even when it gets wet, shakes on the road, or hits something, which is common in trailer mounted environments. The strong walls of the tank don’t bend or break under mechanical stress, so the reservoir stays completely sealed for years of daily use without developing the fatigue cracks or corrosion leaks that can happen with aluminum or thin-gauge steel alternatives.

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

This VEVOR dump trailer hydraulic pump comes pre-assembled. All you have to do is fill it with hydraulic fluid, connect the battery lead, and attach the hose before you can use it. No need for sub-component alignment, internal assembly, or special tools means operators can install it without specialized hydraulic system training.

SAE #6 port fittings are a standard in the industry, so most hydraulic supply stores carry hoses and adapters compatible with them. It eliminates sourcing delays and thread mismatch errors that come with proprietary port configurations. It means that first-time installations can be done correctly without needing extra fittings or trips back to the supply house.

Leak-Resistant Sealed System Design Maintains Full Hydraulic Integrity Across Vibration-Heavy Environments

Seals that fit perfectly at all internal pump connections and external connection points form a closed hydraulic circuit that prevents fluids from leaking out, even under high pressure for extended periods. Leak resistance is very important for mobile caravan applications because road vibration and thermal expansion cycles put significant stress on connection points, which weak seals can’t withstand over time.

A hydraulic circuit that keeps the seal in good condition helps maintain pressure in the system between cycles. It ensures that actuators respond immediately with full force when the next lift command is issued. Operators who fix small leaks before they cause a gradual pressure drop also prevent the gradual drop in performance that leads to incomplete bed raises, slow retraction, and, eventually, overworking the pump when the fluid volume is low.

Versatile Hydraulic Power Unit Runs Dump Trailers, Scissor Lifts, Liftgates, and Small Presses

This hydraulic power unit can be used on dump trailers, liftgates, scissor lifts, lift tables, small hydraulic presses, and bucket conveyors. It meets the pressure and directional control needs of most light- to medium-duty industrial hydraulic circuits from a single, compact unit. The double acting control logic and 3,200 PSI capacity can work with both simple caravan beds and more complex multi stage lift equipment without requiring any system changes.

For shops and contractors that use a wide range of hydraulic equipment, switching to a single pump platform reduces the number of spare parts they need to keep on hand, makes it easier to train technicians, and lowers overall maintenance costs across the entire fleet. The standardized SAE fittings and 12V power input make it easy for the unit to integrate with new equipment setups.
