Shopping for a dump trailer hydraulic pump means balancing power, speed, and how much you want to assemble yourself. You also need to think about reservoir size, because too little oil means the cylinder won't fully extend. The usual starting point is a self-contained power unit with enough reservoir capacity for your cylinder, and price and cycle time quickly become the deciding factors.
Quick verdict
If you need a 12V DC double acting power unit, this is a complete package at USD 439.00. The pump is rated at 2500 PSI with 1.25 GPM flow at that pressure, which suits many dump trailer builds.
Who it suits
The 8-quart plastic tank keeps the total weight at 17 pounds, which makes it practical for a trailer frame. This suits a builder who wants the reservoir and pump in one unit and prefers a wired remote over a manual valve on the cylinder. It's also a good fit if you're comfortable doing the basic wiring yourself.
What stands out
The SAE 6 ports are a clean fit for standard hydraulic fittings, and the pump provides powered lowering rather than relying on gravity. That gives you more control when you're placing the dump bed precisely, especially at the end of the dump cycle.
Meaningful trade-offs
The flow rate is the main limitation. At 1.25 GPM at 2500 PSI, this is not a high-speed unit, so larger cylinders will move more slowly. The plastic reservoir is lighter than some alternatives, but it's still a plastic tank to protect from damage. The manual is only available on request, so ask for it if you need a reference.
Hydraulic Pump for Dump Trailer, 12 Volt DC Power Unit Double Acting 8 Qt tank
The reason to choose this power unit is that the SAE 6 ports and a wired remote are part of the package, so you don't have to track down those extras separately. The limitation to keep in mind is that the manual is only available on request, so plan to ask for it if you need a reference.
Bottom line
At USD 439.00, this Magister Hydraulics unit is a sensible pick for a dump trailer. It gives you a straightforward hydraulic power setup.
