Choosing a 12V hydraulic power unit for a dump trailer comes down to two questions: how much control do you need, and how much reservoir capacity fits your trailer? The four units here span from $143.99 to $439, with single-acting and double-acting designs. Single-acting systems lift the cylinder and then let gravity lower it; double-acting systems use hydraulic pressure for both raise and lower, which gives you more control on uneven ground or with heavy loads.
Quick take
For most dump trailers, the double-acting unit at $240 is the middle ground to measure against: it has a large metal tank, SAE #6 ports, and a 3200 psi rating. If you want the highest price in the group and a branded listing, the Magister Hydraulics unit is the one to look at. The compact double-acting unit at $160 is the floor for double-acting control, and the single-acting pump at $143.99 is the easiest entry point.

- If you want the least expensive single-acting setup: the single-acting pump.
Product notes
Magister Hydraulics 12V Power Unit
The highest-price unit in this group is the only one that pairs a 1.6 kW motor with a listed 1.25 GPM at 2500 PSI, so it's designed for faster cylinder movement. It comes with a wired remote for powered raise and lower, and the 17-pound total weight includes a plastic reservoir. The listing also includes a one-year warranty and a US country of origin, which may matter if you want support after the sale. The main limitation is cost: this unit costs substantially more than the other double-acting options, and the plastic tank contrasts with the metal tank on the mid-price unit.
Double Acting Unit with Remote Pendant
This mid-price option uses a metal tank and a 15-foot remote pendant, so you can stand away from the trailer while raising or lowering. It's rated at 3200 psi for port A, which gives it more pressure headroom than the 2500 psi rating on the Magister unit. That makes it a good fit for trailers that occasionally carry heavier loads. The trade-off is flow: at 0.91 GPM, it moves oil more slowly than the 1.25 GPM of the higher-price unit, so the dump bed will cycle at a more deliberate pace. If you want a sturdy tank and a remote without paying the top price, this is the strongest match.
Compact Double Acting Power Unit
This is the only new open-box listing in the group, and it's priced between the single-acting unit and the larger double-acting pump. It uses a hydraulic gear pump and an electric motor, and the double-acting function lets you control both directions. For someone with a smaller trailer or limited mounting space, this unit offers double-acting capability without the bulk of a large tank. The open-box condition is the main caveat, so this pick is best for buyers who are comfortable checking a unit before installing it. It's a reasonable way to get double-acting control while keeping the purchase price down.
Single Acting Dump Pump
The least expensive unit in the group is also the only single-acting model, which means it powers the cylinder up and lets gravity bring it back down. It uses an 800W copper-wire motor and a remote control system, and the listing includes a 10-year manufacturer warranty. This makes it a straightforward choice if your dump trailer is a standard gravity-lower setup and you want to spend as little as possible. The limitation is control: you can't apply hydraulic pressure to force the bed down, so if you work on uneven terrain or with materials that stick, a double-acting unit will serve you better.
Final recommendation by use case
- For most trailers that need powered raise and lower without the top price: the mid-price double-acting unit with the metal tank.
- For the highest listed flow, if price is secondary: the Magister Hydraulics unit.
- For a compact double-acting unit on a tighter budget, if open-box condition is acceptable: the 6-quart unit.
- For a simple gravity-lower trailer on a strict budget: the single-acting pump.
