VEVOR 4 Quart Double Acting Hydraulic Pump

The VEVOR Hydraulic Pump features a 12V DC, 1.6kW motor and a 4 quart metal reservoir designed for reliability and long life. Its double-acting mechanism enables both lifting and lowering actions, allowing for efficient dump trailer operation. The unit can withstand pressures up to 3200 PSI on the A port and 1500 PSI on the B port. A key convenience feature is the 15-foot remote pendant for long-distance control, enhancing usability. Made from corrosion-resistant materials, this pump offers durability and quick response times for heavy workloads.
3 Quart Plastic Hydraulic Fluid Reservoir Kit

This 3 Quart Plastic Hydraulic Fluid Reservoir is adaptable for use with hydraulic dump trailers manufactured by Load Trail and similar brands. Made from durable plastic, it serves as a fluid storage component rather than a power unit. Its compact size and compatibility provide a cost-effective solution for maintaining hydraulic fluid supply in smaller trailer systems. This reservoir is suitable where metal tanks are not required or preferred.
Johnsen’s 5594 Hydraulic Jack Oil

Johnsen’s 5594 Hydraulic Jack Oil is formulated to perform effectively across a wide temperature range, making it suitable for various hydraulic equipment, including dump trailers. It contains anti-foam additives to ensure smooth pump operation and rust inhibitors that protect system components from corrosion. With a 32 oz. bottle size, it’s ideal for topping off or small hydraulic systems and maintaining reliable fluid performance during operation.
Mophorn 8 Quart Double Acting Hydraulic Power Unit

The Mophorn Hydraulic Power Unit features an 8 quart metal reservoir paired with a 12V DC, 1.6kW motor capable of delivering up to 0.91 GPM flow rate. This double-acting pump supports both lifting and lowering hydraulic actions, with maximum pressure ratings of 3200 PSI and 1500 PSI on respective ports. It includes a 15-foot remote pendant for ease of control. The robust construction resists corrosion and wear, suitable for heavy-duty dump trailer applications requiring consistent high performance.
LOSTAR 8 Quart Poly Power Unit Reservoir for Hydraulic Systems

This LOSTAR 8 Quart Polyethylene Reservoir is designed to serve as a durable fluid tank for a range of hydraulic systems including dump trailers, boats, and RVs. Its flat bottom design stabilizes placement and the reservoir helps filter impurities that could harm hydraulic pumps or valves. Its universal application and good sealing properties make it an effective reservoir replacement or upgrade option, especially where corrosion resistance and lightweight materials are preferred.
Buying Guide for Hydraulic Oil and Power Units for Dump Trailers
When selecting hydraulic oil or power units for dump trailers, consider the following:
Hydraulic Oil Selection
- Compatibility: Ensure the hydraulic oil matches the manufacturer’s specifications regarding viscosity and additives.
- Temperature Range: Choose oil formulated to perform in your operating temperature conditions to avoid viscosity breakdown.
- Additives: Look for anti-foam and rust inhibitor additives to prolong component life and maintain efficient operation.
- Maintenance Frequency: Higher quality oils often extend change intervals, reducing downtime.
Hydraulic Power Unit Selection
- Motor Power: A 12V DC motor rated around 1.6kW delivers reliable output for typical dump trailer needs.
- Reservoir Capacity: Proper reservoir size (usually 4 to 10 quarts) ensures sufficient oil supply without excess weight.
- Material: Metal reservoirs provide durability; plastic/polyethylene reservoirs reduce weight and resist corrosion.
- Pressure Rating: Ensure the unit supports pressure requirements of your hydraulic cylinders (up to 3200 PSI common).
- Acting Mechanism: Double-acting pumps allow simultaneous lifting and lowering functions, enhancing operational control.
- Remote Control: Units with remote pendant control improve safety and convenience during operation.
- Durability: Look for corrosion resistance and protective features to extend the lifespan of the unit in harsh environments.
Additional Considerations
- Installation Compatibility: Match pump ports and reservoir dimensions to your trailer’s hydraulic system.
- Maintenance and Serviceability: Choose units and oils with accessible maintenance procedures and availability of parts.
- Environmental Factors: Consider oil spill containment and eco-friendly formulations if working in sensitive areas.
