If you're shopping for a hydraulic power unit, the first decision is where the lifting happens. One pump is built for a stationary car lift that runs on shop power. The other is made for a dump trailer or truck, where the pump has to ride along with the vehicle. These two units are close in price, but they solve very different jobs, so choosing the right one comes down to power source and portability.
Quick Verdict
For a fixed shop with 110V power, go with the 110V car lift power unit. For mobile dumping work, go with the 12V dump trailer pump. The price gap is small enough that the real deciding factor is where and how you need to lift.

Consider Your Setup
Think about how often the pump moves. A stationary shop lift puts the pump in one place, so a larger reservoir and higher pressure rating matter more for repeated heavy lifts. A dump trailer needs a pump that can travel with the vehicle and be controlled without walking over to it. Matching the power source to the job site matters more than the narrow price gap between these two.
Where Each Product Wins
The car lift unit wins for stationary work because its 2.2 kW motor is rated to reach 3,200 psi. The dump trailer unit wins for mobile convenience because it includes a remote-control system and is compact enough to ride on a trailer or truck.
Product Notes
Returned 110V Car Lift Hydraulic Power Unit 2.5 Gal /10 Qt Post Hydraulic Pump
This is the stationary choice among the two. Its 2.2 kW motor is rated for a maximum pressure of 3,200 psi and flows at 1.7 GPM, giving it a clear role for heavier shop lifting. A 2-year manufacturer warranty covers the unit, even though it is listed as used and returned. That used condition is the main limitation: you are not getting a new part, and the returned status is right in the title. If you are running a car lift in a shop and want more hydraulic capacity for heavier vehicles, this unit is the stronger fit. If new condition matters more to you, the dump trailer pump is the one to pick.
Hydraulic Power Unit 12V, Single Acting Dump Hydraulic Pump for Dump Trailer
This is the mobile choice. It's built around an 800W copper-wire motor and can serve as a direct replacement for a remote-control hydraulic system on a dump trailer or truck. The unit is listed as new, which is a clear advantage after looking at a returned option. The limitation is setup: assembly is required, and hydraulic oil is not included. You'll need to add oil and put the pieces together before it can lift a dump bed. For a vehicle-powered dumping system where convenience and portability matter, this new pump is the practical pick, especially if you prefer a brand-new power unit over a returned one.
Final Choice by Use Case
Choose the Car Lift Hydraulic Power Unit at $155.99 when your lift stays in one place and shop power is available. It is built for stationary heavy lifting.
Choose the Dump Trailer Hydraulic Pump at $143.99 when you need to lift a dump bed away from a wall outlet. It costs 8% less and is the mobile option.
