8 Quart Double Acting Hydraulic Pump
8 Quart Metal Reservoir & Double Acting & 12V DC & 2 Additional SAE#6 Connectors 

Our power units are some of the most reliable and durable units in the industry for use with dump trailers, dump trucks, RV's, boat lifts, lift gates, tow trucks, wreckers, car haulers, agriculture equipment, snow plow equipment and a variety of other applications that require a powerful and compact hydraulic pump.

About the item:

【One Force Lifts a Thousand Pounds】The hydraulic pump is equipped with a 12V DC motor (rated at 1.6KW) and an 8 quart/8 liter oil tank. The maximum pressure at the outlet can reach 3200PSI/22MPa with your double-acting cylinder can easily lift at least 5 tons of weight.
【Double Acting Hydraulic Power Units】This double-acting hydraulic pump must be used with a double-acting cylinder. The hydraulic pump will have an outlet and return port when controlling your cylinder up and down (for up: A2 for outlet and A1 for return; for down: A2 for return and A1 for outlet), so your cylinder must also have two ports to work.
【The King of Cost Performance】This brand new hydraulic pump is perfect for replacing your dump trailer pump, and you get a great performing hydraulic power unit for half the cost of a dump truck pump store. And it can also be used as a power unit for other hydraulic systems such as garden tractors, forklifts, stackers, small or medium-sized lifting platforms, etc.
【Easy to Use】This hydraulic power unit can be used directly with the controller (included) after connecting your cylinder with the oil pipe (not included) and connecting the 12V DC power supply (not included) according to the instructions. The interface type of the oil port is (9/16")SAE#6, and the suitable hydraulic oil viscosity range is 22-46mm²/s.
【Friendly Service】This product provides 30 days quality assurance, if there are any quality problems can be unconditionally replaced. Please leave us a message if you have any questions during use.

NOTE

Pictured is a double acting pump, the double acting pump can be purchased with a 4, 6, 8, 10 or 15 qt reservoir.

Precautions:

The factory production of a hydraulic power unit when leaving the factory, the system pressure has been set. If  you want to change, the user according to the actual situation on their own through the knob to adjust the system pressure regualting valve, but no more than nominal pressure of the system.
Carefully check the motor and the electromagnetic valve connection. It is strictly prohibited to pick up.
In the installation and debugging for  the first  time, we must  keep the internal fuel tank oil level, after a work cycle, oil tank should be made up, but not be too full.
Electrical and electromagnetic valve connection should pay special attention to the supply characteristics( ac, dc voltage and has the same sign. Ac power motor shell must be reliable grounding, forbidden ground operation. The motor terminal box note waterprrof, moistureproof. Connection for the first time, inching motor check direction, from the motor back end, spin to counterclockwise. Absolutely forbidden motor reverse reverse rotation and oil-free idling.
When the gas tank hydraulic oil must be filtered, filtration precision is not lower than 25 microns.
Power unit can't filter the impurities inside the hydraulic cylinder. So the hydraulic cylinder internal must clean. Lest cause valve failure. Tubing must also be clean.

Operation Method :
1. According to hydraulic principle diagrams, with clean connecting hydraulic powe unit and oil cylinder tubing.
2. According to the motor and the power of the electromagnetic valve marked characteristics( ac, dc voltage is properly connected. )
3. Inching motor observe any abnormal phenomenon. In actuators,without load, start the electric, short run test, check whether all the parts run smooothly, determine and correct after loading step by step to normal operation.
 Hydraulic Pump for Dump Trailers
8 Quart Metal Reservoir & Double Acting & 12V DC 
This hydraulic pump is a double-acting power unit for both lifting and lowering. It has an 8-quart sturdy metal reservoir and is designed with a 12V DC motor that can provide strong power for hydraulic systems like dump trailers, forklifts, lifting platforms, etc. 

Maintenance:

We must keep the actuators, and pipeline cleaning, prevent dirt from entering the system.
We must keep the tank oil level, after a work cycle, proper fill oil. Such as pump suction air will cause the damage of pump and the damage of the seal.
100 hours after the running of hydraulic oil for the first time to join, change the new oil. after a year(1500 hours) to replace a new oil.
Hydraulic iol viscosity for 22 and 46 was commonly/s.
Working environment temperature high use hydraulic oil of high viscosity, low working environment with low viscosity hydraulic oil.
