Two hydraulic power units, two very different jobs. One is built for stationary lifting, the other for mobile trailer work. The right choice depends on your power source, the lifting action you need, and the reservoir capacity that matches your equipment. This head-to-head shows where each unit excels and which one belongs on your lift or trailer.
Quick Verdict
For a stationary shop lift, go with the 3450RPM Single Phase Hydraulic Power Unit. For a dump trailer, go with the 20 Quart Double Acting Hydraulic Pump.

What the Specs Mean for You
One unit is meant to be plugged into a workshop electrical supply. Its motor drives a pump that pushes hydraulic fluid to lift a load, and the return happens as the load comes back down. That setup is common for shop lifts.
The other unit is a self-contained mobile system. Its motor is designed to run off a vehicle's electrical system, and its valve routes fluid in both directions. That means the cylinder can push the trailer bed up and pull it down under power, which is exactly what a trailer needs.
Both units come ready to connect with their respective fittings, so the choice comes down to the environment where you'll use them.
Where Each Product Wins
The single-phase unit fits a shop environment. It's built for vehicle lifts and suits a fixed installation where a constant power supply is available.
The double-acting pump fits a mobile setup. It's built for dump trailer work and handles the start-and-stop cycle of a trailer load.
Product Notes
3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor
This power unit is designed for stationary lifting jobs. It uses a 2.2kW 220V AC motor spinning at 3450 rpm, with a 16-quart (4-gallon) reservoir. The max relief valve setting is 2950 psi, which suits vehicle lifts that lower by gravity. It arrives fully assembled, with simple wiring, operating instructions, and extra connectors. At $221.83, it's about $18 less than the DC unit, and it includes a 1-year manufacturer warranty. The limitation is its single-acting action: it powers the lift up, but you need gravity or another mechanism to bring the load down.
20 Quart Double Acting Hydraulic Pump 12V DC Dump Trailer Hydraulic Power Unit
This unit is built for mobile hydraulic work. It runs on 12V DC with a 1.6kW motor and a 20-quart metal tank. The double-acting design powers both up and down, making it a natural fit for dump trailers. It has a rated pressure of 3200 psi on port A and a flow rate up to 0.91 GPM, connecting through an SAE #6 port. The included 15-foot remote pendant lets you operate the trailer from a distance, and you get two extra SAE #6 fittings. At $240.00, it costs about $18 more than the AC unit, but it adds portability, remote control, and powered lowering for a trailer.
Final Choice by Use Case
Choose the 3450RPM Single Phase Hydraulic Power Unit for a shop vehicle lift. Choose the 20 Quart Double Acting Hydraulic Pump for a dump trailer. If you're still deciding, match the unit to your power source: one needs a wall outlet, the other needs a vehicle electrical system.
