Nakkaa 12V DC 10 Quart Hydraulic Power Device Double Acting Hydraulic Pump

Brand: Nakkaa

Check Price on Amazon »

Ideal for those who frequently dump heavy loads and want extra thermal capacity without sacrificing reliability.

When your dump trailer handles serious weight, the Nakkaa 10 quart double acting pump gives you a larger oil reservoir that keeps the system running cooler during extended use. The motor is the same 1.6 kW unit found in the 8 quart version, so you still get 3200 PSI on port A and 1500 PSI on port B. The added volume means less frequent refilling and more consistent lifting cycles, especially helpful if you’re hauling dense materials like sand or rock.

The rugged steel tank offers the same durability as the smaller model, protecting the pump from job site abuse. Installation is identical—SAE #6 ports and a 15-foot remote make it easy to get up and running. If your trailer has a larger cylinder or you simply want the peace of mind that comes with extra hydraulic fluid capacity, this pump is a smart upgrade. It also works well as a replacement unit for older pumps that just don’t have enough power anymore.

Buyer’s Guide: What to Consider

Choosing the best 12 volt hydraulic pump for your dump trailer comes down to a few key factors that affect performance, durability, and ease of use. The table below outlines what you need to consider before making a purchase. Understanding these elements will help you match the right pump to your trailer’s size, cylinder type, and workload.

  • Tank Size (Quarts): The reservoir capacity determines how much hydraulic fluid your system holds. Larger tanks (10–13 quarts) keep oil cooler during continuous use and require less frequent refilling. Smaller tanks (4–8 quarts) are lighter and fit in tight spaces but may overheat under heavy, extended operation. Choose based on the weight you haul and how often you dump.
  • Single-Acting vs. Double-Acting: Single-acting pumps only push fluid to raise your trailer bed; gravity brings it back down. Double-acting pumps control both lifting and lowering, which is useful if you need to lower a heavy load under power. Check your trailer’s cylinder type before buying—most dump trailers use single-acting cylinders, but double-acting offers more control.
  • Maximum Pressure (PSI): Pressure determines how much weight your pump can lift. Most units in this guide offer up to 3200 PSI, which is sufficient for lifting 5 tons or more. If your trailer carries lighter loads, a pump with 2500 PSI may save money, but always verify your cylinder’s rating first.
  • Motor Power and Flow Rate: All featured pumps use 1.6 kW (2.15 HP) 12V DC motors, but flow rates vary from 0.91 to 2.0 GPM. Higher flow means faster lifting, while lower flow gives more control. Match the flow to your cylinder’s ideal speed—too fast can be jerky, too slow can be frustrating.
  • Tank Material: Steel vs. Plastic: Steel tanks are more durable and resist impact damage, making them ideal for rough job sites. Plastic tanks are lighter, won’t rust, and are less expensive, but they can crack if hit hard. Consider your working environment—steel for outdoor abuse, plastic for clean, indoor or occasional use.
  • Connector and Hose Compatibility: All pumps here use SAE #6 ports with 9/16-18 UNF threads, the industry standard for most dump trailer hoses. Before purchasing, confirm your existing hoses match this size. If not, adapters are available, but they add extra points of potential leakage.
  • Ease of Installation and Included Accessories: Many pumps come pre-assembled and include a wired remote control (15-foot or longer). Check if hydraulic oil is included—most are not. Look for clear instructions and all needed mounting hardware. A pump that arrives ready to go saves you time and frustration.

Conclusion

No matter what size or type of dump trailer you own, there’s a 12 volt hydraulic pump that fits your needs. Compact models like the generic 4-quart unit work well for small trailers and tight budgets. For heavy-duty, continuous use, the Nakkaa 13 quart single-acting pump offers unmatched capacity. Double-acting pumps from VEVOR, DC HOUSE, and TOPEMAI give you precise control over both raising and lowering.

Remember to match the pump’s pressure and flow to your cylinder, choose a tank size that suits your workload, and pick a material—steel or plastic—that can handle your job site conditions. With the right pump, you’ll save time and effort, turning a labor-intensive task into a simple push-button operation. Use this guide to compare the options, and you’ll be dumping loads with confidence in no time.
