12V DC Single Acting 10 Quart Hydraulic Power Unit 3200 PSI 2 GPM SAE#6 Ports

12V DC Hydraulic Power Unit for Dump Trailer Lifting

This 12V DC single acting 10 quart hydraulic power unit delivers up to 3200 PSI relief pressure and 2 GPM flow from a compact 2.5 gallon metal reservoir, so a dump trailer bed, car lift or scissor table rises smoothly on the first press of the button. SAE#6 ports match common trailer hoses, and the two button remote with a 4 meter cable keeps the operator clear of the load. Every hydraulic power unit is assembled, filled and pressure tested before packing, and ships with motor, gear pump, manifold, valve block and remote already fitted.

Why This Power Pack Holds Up in Daily Work

• Stable pressure under load: the gear hydraulic pump and adjustable relief valve keep working pressure steady at 3200 PSI, so the cylinder lifts at a constant speed instead of labouring at the top of the stroke.
• Efficient 12V DC motor: 1600 W, 2800 RPM, S3 duty motor draws on a normal vehicle battery and returns the bed to the ground without hunting for a power source on site.
• 10 quart metal reservoir: a 2.5 gallon steel tank holds enough oil for a full lift and lower cycle, which keeps oil temperature down and reduces foaming on repeated use.
• Single acting simplicity: one pressure hose to the cylinder, a release valve for controlled lowering, and no return line to route along the frame.
• Service friendly layout: SAE#6 ports, a bolt on manifold and a removable motor cover mean a pump or solenoid swap can be done in the workshop rather than at the roadside.
• Protected finish: the reservoir and motor cover are coated against rust and road spray, which matters when the pack sits behind the wheels of a trailer.

Buyer Questions

Q: Is this hydraulic power unit single acting or double acting?
It is single acting: one SAE#6 pressure port feeds the cylinder, and the solenoid release valve returns the oil to the reservoir for gravity lowering. If your cylinder has two hoses, ask us for the double acting version of the same body.

Q: Will the 12V DC motor run from a standard trailer battery?
Yes. The motor is rated 12 volt, 1600 W at 2800 RPM and works on a short duty cycle, so a normal 12V battery with a healthy charging circuit is enough. Keep cable runs short and use the supplied 4 meter remote wiring rather than extending the motor leads.

Q: How much oil does the 10 quart reservoir take?
The metal reservoir holds about 9.5 litres. Fill with ISO VG32 or VG46 hydraulic oil with the cylinder fully retracted, then cycle the unit once and top up.

Q: What can a 2 GPM power pack lift?
Lifting force comes from the cylinder bore, not from the pump alone. At full relief a 50 mm bore cylinder produces roughly 4.4 tonnes of push, and the 2 GPM flow raises that cylinder at a practical speed for trailer and lift work.

Q: Do the SAE#6 ports match my existing hoses?
SAE#6 is a 9/16-18 UNF port, the common size on trailer and lift cylinders. Send us your hose end photo and we will confirm before shipment.

Q: What is the minimum order and lead time?
Minimum order quantity is 20 units, with a 15 working day delivery time. Sample orders and mixed gear pump displacements can be arranged.

Selection and Installation Notes

Match the unit to the cylinder before ordering. A 10 quart tank suits single rod cylinders up to roughly 20 litres of swept volume; for longer stroke tipper rams or two cylinder setups, specify the 18 litre tank so the pump never runs dry at full extension. Mount the pack on a flat, reinforced plate with the reservoir level, keep the filler cap accessible, and route the pressure hose without sharp bends. Use a return line filter on the release circuit if the trailer works in dust, and check the relief setting after the first ten cycles. Ambient temperature above 40 C calls for a larger tank or an oil cooler.

Quality Control and Ordering Information

Each unit is assembled in our Ningbo workshop from a machined gear pump, a wound 12V DC motor, a machined aluminium manifold and a tested solenoid coil. Units are run on a test bench to check relief pressure, flow and leak tightness before the reservoir is drained for shipping, and the results travel with the packing list so importers can trace a batch. Bodies carry CE and ISO certification, and drawings plus schematics are available for engineers who need to confirm mounting points. Units are packed one per carton on pallets, payment terms include T/T, L/C and Western Union, and supply ability is 2000 pieces per month.

Tell us your cylinder bore, hose length and mounting position, and our team will confirm whether this unit or a larger tank variant fits your trailer or lift design. Contact us for a quotation and current lead time.
