DC HOUSE L12t160123YYDLDY3S-1 4-Quart Double-Acting Hydraulic Pump, 12V

A dump-trailer setup with a double-acting cylinder needs a power unit that can control both raising and lowering. The DC HOUSE 4-quart hydraulic pump runs on 12V DC and operates through both hydraulic ports for those two-way movements.

Need a raise-and-lower setup rather than a pump focused on lifting alone? Its included remote control switch provides a direct way to command the two directions.

With a 1.6 kW motor and pressure up to 3,200 PSI at ports A and B, this unit is designed for double-acting hydraulic applications, including dump trailers and other equipment using double-acting cylinders.

Getting the most from it

For a dump trailer, the pump sends hydraulic oil through port A or B to raise or lower the cylinder. Both ports deliver pressure, supporting controlled movement in either direction. That makes this a different approach from a single-acting power unit, which is designed around one powered direction, choose a double-acting pump when the cylinder and equipment need powered raising and lowering.

The unit arrives preassembled. Add filtered hydraulic oil with a viscosity of 22–46 mm²/s, then connect the power leads and hydraulic hoses. The stated power-wire recommendation is 20–25 mm² copper wire. The pump uses an SAE #6 (9/16-18 UNF) connector, and the outlet fitting has a 14 × 15 mm inner thread and an 18 × 1.5 mm outer thread. Matching those connections to the hydraulic line makes for a more straightforward installation. The included remote switch is used to control raising and lowering.

Beyond dump trailers, the listed applications include container-truck tailboards, hydraulic wood splitters, small presses, lifting platforms, garden tractors, forklifts, and stackers. In each case, the relevant fit is use with a double-acting cylinder.

Pros

The main advantage is two-way operation from a 12V DC power unit: the same pump supports both raising and lowering through its A and B ports. The remote switch keeps the controls at hand during operation, while the 4-quart reservoir provides a defined capacity for selecting a pump to suit a trailer or other double-acting-cylinder application. Its listed connector dimensions and recommended oil viscosity also give practical reference points when planning the hydraulic and electrical connections.

Customer feedback describes the pump as straightforward to use and install, while opinions are mixed on overall quality and load stability. Some customers report fitting mismatches, leakage, or durability concerns. The published connector details are useful when matching the pump to a particular hose and cylinder setup.

Buying verdict

For a dump-trailer owner or equipment operator who needs a 12V power unit for a double-acting cylinder, this DC HOUSE model combines remote-controlled raising and lowering with a 4-quart reservoir and pressure up to 3,200 PSI. Its stated connection details and setup requirements help define the installation, and its range of listed applications makes it relevant beyond trailers wherever double-acting hydraulic control is needed.
