In hydraulics pneumatics, the first decision is power source. One unit is designed around a 220V AC supply and the other around a 12V supply. Their prices are $221.83 and $160.00, so the cost difference is easy to see. The harder part is deciding which pump action and reservoir size fit your equipment.
Quick verdict
The 3450RPM unit suits a vehicle-lift application where gravity returns the load. The 12V Double Acting Pump suits a compact hydraulic system where you want the lower price.

Where each product wins
The 3450RPM unit has the edge if the max relief pressure of 2950 psi matters most for your job. The 12V unit has the edge if a compact design and a lower price fit your hydraulic system better.
Product notes
3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor
The strongest case for this unit is its 2HP motor and 2950 psi relief valve setting. The 2.2KW motor draws 18A at 230V, and a 1-year manufacturer warranty is included. The description targets vehicle lifts and gravity-down operation, and the unit is sold fully assembled with operating instructions and extra connectors. The trade-off is the single-acting pump action: it extends under pressure and returns by gravity, so it is not built to push and pull a double-acting cylinder. If your application uses gravity return, this is the more substantial option.
Hydraulic Power Unit 12V Double Acting Pump 6 Quart
This pump appeals to anyone who wants a double-acting hydraulic gear pump without spending more than needed. The double-acting action lets fluid move the cylinder in both directions, and the 6-quart reservoir keeps the package compact. The gear pump design contributes to that compact size. It is listed as New - Open box, so you are getting an unused unit but not a factory-sealed one. The limitation to weigh is the 12V power requirement, so be sure your system is set up for it. If your equipment uses a 12V supply, this is the practical pick.
Final choice by use case
Choose the 3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor for vehicle-lift work. Choose the Hydraulic Power Unit 12V Double Acting Pump 6 Quart for a compact hydraulic system.
