In the hydraulic power unit world, the biggest decision is not brand-it's where and how you'll use the pump. One is built for a dump trailer running off a 12V battery. The other is a 220V single-phase unit meant for a shop lift that lowers by gravity. Between the Magister Hydraulics 12V DC dump trailer pump and the findmall 3450RPM single-phase power unit, your choice depends on whether you need mobile power or fixed shop pressure.
Quick verdict: The Magister Hydraulics 12V DC pump is the clear pick for mobile dump trailer work because it operates from a 12V battery and gives you power up and power down with a wired remote. The findmall 3450RPM single-phase unit is the better value for a shop lift with gravity return, offering a larger 4-gallon reservoir and a higher 2950 PSI relief setting for $221.83.
Listed price and spec comparison:
| Product | Price | Operation | Reservoir | Max Pressure | Motor |
|---|---|---|---|---|---|
| Hydraulic Pump for Dump Trailer, 12 Volt DC Power Unit Double Acting 8 Qt tank | USD 439.00 | Double acting (power up/down) | 8 quarts | 2500 PSI | 1.6kW, 12V DC |
| 3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor | USD 221.83 | Single acting (gravity down) | 16 quarts (4 gal) | 2950 PSI | 2.2kW, 220V AC |
Where each product wins:
- The Magister Hydraulics 12V pump wins for mobility: it runs from a 12V battery, includes a wired remote controller, and has a double-acting cylinder for controlling descent.
- The findmall 3450RPM unit wins on price, reservoir size, and pressure: it costs $217.17 less, holds twice as much fluid (16 quarts vs. 8 quarts), and its relief valve is set higher at 2950 PSI.
Hydraulic Pump for Dump Trailer, 12 Volt DC Power Unit Double Acting 8 Qt tank
The Magister Hydraulics pump is a 12V DC power pack with an 8-quart plastic reservoir, so you can install it directly on a dump trailer and power it from the truck battery. Because it is double acting, the cylinder extends and retracts under pressure-no gravity or spring return is needed. The system includes a wired remote controller, which is a handy feature when you don't want to climb out of the cab. Its 1.6kW motor delivers 1.25 GPM at 2500 PSI, and the unit weighs just 17 pounds. The tradeoff is cost: at $439.00, it is almost double the findmall unit. Also, the 8-quart tank is smaller, so if you need more oil volume for a large cylinder, the findmall's 4-gallon reservoir gives you more capacity.
3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor
The findmall power unit is a 220V AC single-phase motor rated at 2.2kW (2HP) with a 16-quart (4-gallon) reservoir. It runs at 3450 RPM and draws 18A at 230V, giving it a max relief valve setting of 2950 PSI. That pressure and tank capacity make it well-suited for a vehicle lift that uses a gravity-return cylinder. Since it is a single-acting unit, it pushes fluid in one direction and relies on gravity to bring the load down-so it won't give you powered lowering like the Magister. The big win is price: at $221.83, it sits well below the $439 Magister pump. The tradeoff is that it's designed for a fixed 220V AC connection rather than mobile 12V trailer use, and the single-acting operation means you need a gravity return in your application.
Final choice by use case: If you're building or upgrading a dump trailer and want to raise and lower it from the cab, the Magister Hydraulics 12V DC pump with its remote and double-acting operation is worth the extra money. If you're assembling a shop lift where the cylinder returns by gravity, and you have 220V single-phase power available, the findmall 3450RPM unit gives you more reservoir capacity and pressure at a considerably lower price.
