4 Quart 12V DC Hydraulic Pump Single Acting 3200 PSI - Dump Trailer

In this review of the 4 Quart 12V DC Hydraulic Pump, the bottom line is simple: it is a practical replacement power unit for owners of dump trailers and small lifting platforms who need reliable, fast lifting from a compact metal reservoir. The reviewer found the pump's single-acting design, rapid-start motor and 4-quart metal tank make it especially useful when a dependable, remotely controlled 12V hydraulic solution is required; the package also includes a 15 ft remote and an extra SAE#6 connector for easier installation.

Key Features

• 12V DC motor: Provides strong, quick starts so the unit delivers hydraulic oil rapidly for faster lifts on dump trailers and beds.
• 4-quart metal reservoir: Metal construction resists cracking and damage, extending the unit's service life in rugged trailer environments.
• High relief pressure: Offers up to 3200 PSI on the A port and 1500 PSI on the B port, giving scope for heavier lifts and safe pressure control.
• Single-acting design: Power up and gravity down operation simplifies plumbing and fits common dump trailer setups.
• Built-in overflow valve: Automatically relieves overpressure for a safer, more reliable system without added components.
• Included remote and connector: The 15 ft remote control and extra SAE#6 connector make installation and remote operation straightforward.

Who It's For

This hydraulic power unit is best for DIY trailer owners, small-fleet operators and maintenance shops needing a compact, fully assembled 12V replacement pump to restore or upgrade remote hydraulic systems. It suits applications like dump trailers, small and medium lifting platforms, and movers where a single-acting, gravity-down return is acceptable.

Those who should look elsewhere include users requiring a double-acting pump, systems needing higher continuous flow than 2 GPM, or installations demanding integrated electronic controllers beyond a simple 15 ft remote. For heavy industrial rigs with bespoke controls, a different power unit would be more appropriate.

Pros & Cons

Pros

• Sturdy metal reservoir reduces the risk of tank cracking and increases durability in trailer use.
• Rapid-start 12V motor gives quick oil output for faster lift cycles on dump beds.
• High relief pressure (3200 PSI A port) and built-in overflow valve add safety when handling heavier loads.
• Comes fully assembled with a 15 ft remote and extra SAE#6 connector, simplifying installation.

Cons

• Single-acting design means down movement relies on gravity, so it is not suitable for applications needing powered down motion.
• Flow rate of 2 GPM may be limiting for larger, faster industrial lifts.
