12 V Volt VDC 12V DC Electric Hydraulic Pump Dump Trailer Truck Liftgate
Monarch M-500 12 volt hydraulic pump. This pump has a valve on top with 3 fittings and 2 control levers. It looks to me like this one will control a single cylinder in one direction like a lift cylinder up, then gravity down. Then the other lever will control a double acting cylinder in both directions. I put 12 volts to the motor and it just sparks, so it either needs brushes, a field, etc.. If you don't work on motors, a new 12 or 24 volt motor can be purchased online for 75.00 plus shipping. This is an abnormal pump, I usually do not get pumps with a control valve of this caliber. With this valve, the pump is very adaptable to many applications. Thanks for looking.
